1. Can't do, can simply do a sta (tube agglutination); If 1:100 + +
the equipment and reagents for brucellosis examination are very professional, and there are few in southern China. The results are not authoritative. In addition, when you give gifts at your work place, you don't have them. The inspection results won't be easy to tell you
if you suspect that you have brucellosis, come to Beijing infectious disease hospital or more professional Inner Mongolia Institute of endemic diseases for examination (the result here is a positive place for the treatment of brucellosis)

2. Hello, from the situation you
described, it's not a big problem. It's not very serious. You don't need to worry too much about it. From the antibody point of view, it belongs to the previous infection. Just pay attention to improving the immunity. If you feel uncomfortable, you can do the test again. At present, it's not a problem.

3. Actually, they are the same place. In the countryside, they are called epidemic prevention stations, but in the city, they are called centers for disease control, which makes no difference
4. At this time, we have to go to the field to mine, that is, there will be mines on the strange map, so we can mine them.
5. No matter what form you use to access the Internet, you will encounter slow computer access (card, network access failure, poor signal, instability, packet loss, high bit error rate, network access failure, offline, crash, unexplained interruption, etc.) wait; In order to make your computer run stably and have a good user interface, you must do the following work: otherwise, it will affect your use:
1: environmental conditions:
A: stable power supply voltage (if necessary, add auxiliary UPS power supply), effective and safe power line section; And comply with the relevant insulation regulations for safe use of electricity; Most of it is the low voltage caused by the small diameter of the user line. After the transformation of two power networks (urban and rural) in China, through the monitoring of users (including remote mountainous areas), the qualified rate of user voltage is 99.98%, and the voltage entering users meets the legal value of national standard. Power grid at any time to use a variety of voltage adjustment means to ensure that the voltage qualified
b: the drying and ventilation temperature is appropriate (fan or air conditioning system should be installed if necessary),
C: the st particle size is small, and the wall and roof should be painted
D: appropriate signal to clutter ratio of transmission line: (ADSL) the noise level of user line should be as small as possible to avoid interference clutter, so that the equipment can work reliably even at a small level
e: network card problem: select a better quality network card.
F: system software configuration: the user does not need to set the IP address, and the system will assign it automatically. If you set DNS, be sure to set it correctly. The operating system is Win98 or me. In the DOS window, type winipcfg to get the DNS region. In the WinXP system, type ipconfig
G: TCP / IP protocol: if users find that browsing is abnormal, they can try to delete TCP / IP protocol and add it again
H: influence of humidity: in rainy season or rainy days and high humidity areas, e to the large conctivity, the conctivity between lines is strengthened, the signal leakage is increased, the signal attenuation is also increased, the line insulation is reced and the line grounding probability is increased, which will make the user signal level of ADSL drop, resulting in line dropping or unstable operation. Humidity will also accelerate the oxidation of the contact surface, repeated oxidation will increase the contact resistance, the increase of contact resistance will lead to transmission interruption
I: the influence of temperature: especially in summer, cats are most afraid of heat, so it is recommended that you:
I-A: put the cat in a ventilated and dry place for natural heat dissipation
I-B: place the cat in a safe place for people, open the cover of the cat box, and use air convection to strengthen the contact surface with the air for heat dissipation
I-C: forced cooling: the cat is equipped with a micro fan to increase the air convection and conct forced cooling
I-D: if you are in it, I suggest you: after the power is cut off, add heat sink to the cat's heating parts
I-E: after the cat is disconnected from the power supply, use a 3mm drill bit to drill a lot of holes in the cat to enhance air circulation and improve heat dissipation conditions;

6. Causes of network instability | friends who often surf the Internet may encounter network instability. Network instability is mainly manifested in that sometimes the network speed is normal, sometimes the network speed is very slow, we can't open the web page or even cut off the network, which seriously affects our work, study, entertainment and so on. So what causes the network instability<
tools / raw materials
computer network
methods / steps
1
network operator problem
at present, the shared bandwidth is used in the home network. When the network is in low peak period, your network speed can be guaranteed, but when the network is in peak period, it can't guarantee the normal network speed. Especially at 8-10 p.m., everyone likes to surf the Internet and watch movies after dinner. At this time, the Internet speed will be quite slow
step reading
2
router reason
when the router works for a long time, it is easy to cause the network state to be unstable, or even to be disconnected. At this time, you just need to power off and restart the router, and wait for a period of time to recover. For this kind of situation, we should develop a good habit of surfing the Internet, and turn off the router power in time when we don't need to surf the Internet<
3
reasons for modem (CAT)
for users using ADSL mode to access the Internet, long-time working of modem (CAT) will also lead to network problems or even network disconnection, which can be recovered after power failure and restart. The solution is the same as the router solution. Develop a good habit of surfing the Internet and turn off the power in time when not in use
4
network card performance
with the continuous upgrading of network bandwidth, the requirements for network card performance will be higher and higher. If the network card performance is too low, it will also cause network instability<
5
wireless stability
with the development of wireless technology, notebook, smartphone, iPad, even desktop computer can be connected to the network through wireless technology. If the stability of wireless procts is not good, it will also lead to network instability
6
multiple computers share a network
when multiple computers share a network, one computer is downloading data at high speed, and the other computer will have network instability, especially when the bandwidth is relatively small. This problem can be solved by limiting the speed of the route
7
Trojan horse or virus
when the computer is infected with Trojan horse or virus, the computer will also run slowly and the network is unstable. At this time, it has nothing to do with the network and routing. Anti virus software should be used to kill the computer virus in time to avoid unnecessary losses
8
there are many reasons for network instability, so network instability often occurs when surfing the Internet. But if you install the real-time monitoring tool of network speed measurement, you can also minimize the impact
end
precautions
there are many reasons for network instability, so we should develop good online habits, understand the most basic network maintenance methods, and minimize the impact

7. There are many reasons for the instability of network speed.
the broadband we connect to, for example, is the water transmission line of the water supply company. One person will use it very quickly. If it is the Olympic Games recently, many people will use it... Naturally, everyone will get less traffic, and the network speed will be very slow.
again, you say you use the wireless network card.
if the network itself is not good, it is in the peak, If you use wireless, the speed is very slow.
another wireless itself is affected by the external environment, such as temperature, humidity, and electromagnetic interference, which will cause network instability. It is recommended that you do not use wireless
2 virus, which is a very big possibility
in addition, try connecting two ADSL cables to a notebook, Then we will see if there will be delay in the notebook. If there is, it is the line problem. On the contrary, there is a great possibility of virus in the network
in addition, we will make a suggestion on switch cascading. Excessive cascading is easy to cause broadcast storm, leading to delay or other problems The network itself has problems
the server where you want to connect to the target website has insufficient bandwidth or excessive load. The solution is very simple, please change the time period or change the target website< As we know, twisted pair is made up of four pairs of wires tightly twisted together according to strict regulations to rece the influence of crosstalk and background noise. At the same time, in t568a standard and t568b standard, only 1, 2 and 3, 6 wires of twisted pair are used. Among them, 1 and 2 are used for transmitting, 3 and 6 are used for receiving, and 1 and 2 must come from a winding pair, 3 and 6 must come from a winding pair. Only in this way can crosstalk be avoided and data transmission be guaranteed. In practice, I found that there are great hidden dangers in the network cable which is not made according to the correct standard (t586a, t586b). One is that the network speed is very slow at the beginning; The other is that the network speed is normal at first, but after a period of time, the network speed becomes slower. The latter situation is very obvious on desktop computers, but the network speed is normal when checking with laptop computers. For this problem, I have found that the network speed slows down e to the network cable not made according to the correct standard, which is also related to the quality of the network card. Generally, the performance of network card of desktop computer is not as good as that of notebook computer. Therefore, when troubleshooting with switching method, using notebook computer to check the network speed is normal can not rule out the problem that the network cable is not made according to the standard. We now require that all network cables should be pressed according to t586a and t586b standards, and laptops should not be used to replace desktop computers when detecting faults< Third, there are loops in the network, which lead to slow network speed
when the number of nodes involved in the network is not many and the structure is not very complex, this phenomenon rarely occurs. But in some more complex networks, there are often rendant spare lines, such as inadvertently connected will form a loop. For example, the network cable from the network center to the computer room 1, and then from the computer room 1 to the computer room 2. At the same time, there is another standby line from the network center directly connected to the computer room 2. If these lines are connected at the same time, it will form a loop, and the data packets will be sent and checked continuously, thus affecting the overall network speed. In this case, it is difficult to find. In order to avoid this situation, we are required to form a good habit when laying the network cable: the network cable should be clearly labeled, and the place where there are spare lines should be recorded. When this kind of fault is suspected, the method of partition and subsection is generally adopted< Fourth, the network speed slows down e to the broadcast storm caused by the hardware failure of network equipment
as the main means of discovering unknown equipment, broadcast plays a very important role in the network. However, with the increasing number of computers in the network, the number of broadcast packets will increase dramatically. When the number of broadcast packets reaches 30%, the transmission efficiency of the network will decrease significantly. When the network card or network equipment is damaged, it will continue to send broadcast packets, which will lead to broadcast storm and paralyze the network communication. Therefore, when the network equipment hardware failure will also cause slow network speed. When such a fault is suspected, the replacement method can be used to replace the hub or switch to eliminate the fault of the hub equipment. If there is no fault in these devices, turn off the power supply of the hub or switch, test the involved computers one by one with the "Ping" command under DOS, find the computer with the faulty network card, and replace it with a new network card to restore the normal network speed. Network card, hub and switch are the devices that are most prone to failure and slow down the network speed< In fact, router WAN port and LAN port, switch port, hub port and server network card may become network bottlenecks. When the network speed becomes slow, we can use the network management software to check the data flow of routers, switches and server ports ring the peak hours of network use; You can also use the netstat command to count the data traffic of each port. According to this, we can confirm the location of network data flow bottleneck and try to increase its bandwidth. There are many specific methods, such as changing the server network card to 100m or 1000m, installing multiple network cards, dividing multiple VLANs, changing the router configuration to increase bandwidth, etc., which can effectively alleviate the network bottleneck and maximize the data transmission speed< (6) the influence of worms slows down the network speed. This kind of virus causes the infected users to send out e-mails as soon as they surf the Internet. The virus selects the random documents in the user's personal computer and attaches them to the random address of the user's address book to send e-mails. Hundreds of such spam are sent out in line, and some are returned to the server in batches. Some backbone Internet appear obvious congestion, network speed obviously slow, make LAN nearly paralyzed. Therefore, we must upgrade the antivirus software in time; In order to improve the security and reliability of the system, the computer should also upgrade and install system patches in time, unload unnecessary services and close unnecessary ports< (7) excessive use of firewalls can also slow down the network speed. Needless to say, only one powerful firewall will be reserved after unloading< 8. System resources are insufficient. You may have loaded too many application programs to run in the background. Please load the software reasonably or delete useless programs and files to free up resources to improve the network speed
4 1. Network card problem: the network card is usually PCI network card or on-board network card. When you choose, you must choose the one with better quality, otherwise the quality of Internet access may be poor
2. Check the circuit in your home to see if the connector is connected properly and if the circuit has passed through any interference source, such as air conditioner, refrigerator, TV, etc, Try to keep a certain distance from these electrical equipment
3. The DNS address can be obtained from the local telecommunication department. In addition, TCP / IP settings can easily lead to unstable web browsing. Generally, it is set to automatically obtain the IP address, but DNS must be filled in
4. Is the firewall level too high
5. Software conflict (the possibility is not great) nowadays, there are two ways of ADSL accessing the Internet: virtual dial-up and private line access. Nowadays, most of the ADSL of indivial users are virtual dial-up. PPPoE virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability
5 if a router is used in the local area network, restart the routing. However, from what you said, it should be caused by the virus. It is recommended that ghost restore the system. If ghost backup is not done, it is better to reload
6. I hope you are satisfied
the broadband we connect to, for example, is the water transmission line of the water supply company. One person will use it very quickly. If it is the Olympic Games recently, many people will use it... Naturally, everyone will get less traffic, and the network speed will be very slow.

8. Several possibilities:
1. Your network is unstable. Either the cat or the thread quality is poor
2. The server of game manufacturer is overloaded because of too many people. instable. Or the quality of the server is not good< br />3 There is something wrong with your network settings< br />4 There's something wrong with your system< br />5 You're poisoned
first of all, check the lines at home to see if the connectors in the house are connected properly and if the lines pass through any interference sources, such as air conditioners, refrigerators, televisions, etc., so as to keep a certain distance from these electrical equipment. It can also replace the indoor lines with more anti-interference network cables. Make sure the wiring is connected correctly. After entering the home, the telephone line is connected to the junction box, and then separated to the voice separator, one line goes to the telephone, one line goes to the modem (the separator is marked). At the same time, ensure that the communication quality of the line is good without interference, and no other equipment that will cause line interference is connected. And check whether the junction box and crystal head have poor contact and whether they are wound in series with other wires. If possible, it's better to use standard telephone line and connect PC with twisted pair attached to ADSL modem. Line is one of the important factors for the quality of image access to the Internet. Signal interference sources such as radio transmitting tower, electric welding machine, tramcar or high-voltage power transformer within 100 meters from the user's cable can make the user offline receive clutter (copper clad steel wire has weak shielding and strong signal receiving ability), causing strong interference to the user's line. The interfered signal is usually the unshielded offline part, because the relay cable has a shielding layer, so the interference and influence are very small. If you use some shielded downlines in places with large interference, it will rece the speed instability or disconnection caused by interference. In addition, the power line should not be paralleled with the ADSL line, in order to avoid crosstalk, resulting in ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference, software conflict. The mobile phone, which has a large radiation, must not be placed next to the ADSL modem, because the mobile phone will automatically find the network every few minutes. At this time, the strong electromagnetic interference is enough to cause the ADSL modem to cut off the current
Second, network cards are usually PCI network cards or on-board network cards. When choosing a better quality network card, it may cause poor quality of Internet access. 10m or 10m / 100M adaptive network card can be used. In addition, many machines share the Internet and use al network cards, which also causes conflicts, which is also worthy of attention. At this time, you should pull up the network card connecting to the LAN or other computers, and only use the network card connecting to ADSL to test the Internet. If the fault returns to normal, check whether there is any conflict between the two network cards
3. ADSL modem or network card setting problem. Now modem generally has two working modes, one is the normal mode of using dialing software, the other is the routing mode of automatic dialing. In normal mode, you don't need to set modem, just use the default mode. The routing mode needs to be set. Modem has its own flash memory, which can save the account and password box settings for automatic dialing. The most common method is to set the IP address of ADSL modem or DNS server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, which can be automatically assigned. TCP / IP gateway generally does not need to be set. But set DNS must be set correctly, DNS address can be obtained from the local telecommunications department. In addition, TCP / IP settings are most likely to cause the situation of not being able to browse web pages. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Other default can be used
IV. ADSL modem synchronization abnormal problem, check whether your phone line and ADSL connection place are in poor contact, or there is a problem with the phone line, the poor quality of the phone is particularly easy to cause drop line, but such a problem is not easy to check, so be sure to use a good quality phone line. If it is suspected that the separator is broken or the ADSL modem is broken, try to directly connect the external line to the ADSL modem without using the separator. The connection between the separator and ADSL modem should not be too long, otherwise it cannot be synchronized. To eliminate the above situation, as long as the ADSL modem is restarted, the synchronization problem can be solved< In addition to the above-mentioned line conditions, there are also computer system problems. For example, the legendary killer caused the LAN to drop. This problem occurs in a large area all over the country. The virus will affect the Internet cafes (LAN) of host agent and router agent. Legend killer is a destructive software that can cheat LAN by ARP and create virtual gateway address to collect login information of Legend game in LAN and analyze it to get user information. Workflow: first of all, broadcast local Mac to LAN by ARP Cheating, so that the workstation in LAN mistakenly thinks this machine is gateway. This process will cause the connection between LAN and Internet to be interrupted, When the user restarts the game and logs in the account, the account information will not be uploaded to the proxy server directly through the gateway, but will be uploaded to the legendary killer software which is carrying out ARP deception, Attack situation: LAN and Internet link speed suddenly slows down or even breaks down. Online games break off the link, and after logging in again, the server will be prompted that there is no corresponding response. It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will. Incorrect settings will cause unstable Internet access. Some operating systems may have compatibility problems with ADSL related components, so you can go to Microsoft to upgrade the system or repair the system. If possible, it can be reassembled. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods< (6) the firewall and IE browser are not set properly. Although ADSL is less likely to be attacked by hackers and viruses, it does not rule out the possibility, especially web viruses and worms. If the virus destroys ADSL related components, there will also be a disconnection phenomenon. If it can be determined that it has been damaged and attacked by the virus, and there is a disconnection phenomenon, it is necessary to check the installed firewall, proxy server software for sharing the Internet, Internet acceleration software, etc. after stopping running such software, it is necessary to test the Internet to see if the speed returns to normal. If the Internet is not stable, you can try to turn off the firewall first, test whether it is stable or not, and then set it accordingly. In addition, firewall or IE browser failure can also lead to normal connection, but can not open the web page< Static electricity is an important factor affecting ADSL, and the power supply in the home is generally not grounded, coupled with the interference of various electrical appliances (such as refrigerators, TVS), it is easy to cause static electricity interference, resulting in frequent disconnection of ADSL in use. Please lead the grounding terminal of the three core socket out of the wire and make a good grounding, which can generally solve the problem of disconnection. General solution: add grounding wire to solve the problem of disconnection< There are two ways for ADSL to access the Internet: virtual dial-up and private line access. Nowadays, most of the ADSL of indivial users are virtual dial-up. PPPoE (point-to-point protocol over Ethernet) virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability. If you are using Windows me or 9x, you can use the following virtual dialing software -- enternet, winpoe, raspppoe. Among them, enternet is now more commonly used, and enternet 300 is suitable for Windows 9x; Enternet 500 is suitable for Windows 2000 / XP. When you have problems with one PPPoE dialing software, you may as well uninstall the software and use another PPPoE dialing software. Please be careful not to install multiple PPPoE software at the same time to avoid conflicts. Because the telephone line is the main way of broadband access, so we must set up a virtual channel. If several kinds of dial-up software are mixed, it will cause conflicts, resulting in network instability. If there is a conflict in the software, try to find out the conflict software, uninstall it or solve it by other methods. For example, some friends BT download will lead to network offline. It may take too many threads to download, resulting in disconnection. In addition, in addition to the above reasons for your own computer, the reasons for QQ and game offline may also be related to their own server restrictions and server attacks or failures.
it has also been reported that the following situations lead to:
you should consider the following possibilities:
1, When you choose, you must choose the one with better quality, otherwise it may cause poor quality of Internet access
2. Check the wiring at home to see if the connector in the house is well connected and if the wiring passes through any interference source, such as air conditioner, refrigerator, TV, etc., and try to keep a certain distance from these electrical equipment
3. The DNS address can be obtained from the local telecommunication department. In addition, TCP / IP settings can easily lead to unstable web browsing. Generally, it is set to automatically obtain the IP address, but DNS must be filled in
4. Is the firewall level too high
5. Software conflict (the possibility is not great) nowadays, there are two ways for ADSL to access the Internet: virtual dial-up and private line access. Nowadays, most of the ADSL of indivial users are virtual dial-up. PPPoE virtual dialing software has its own advantages and disadvantages. After many tests on different operating systems, if the operating system is Windows XP, it is recommended to use its own PPPoE dialing software, which has less current interruption and relatively improved stability.
1. Your network is unstable. Either the cat or the thread quality is poor
2. The server of game manufacturer is overloaded because of too many people. instable. Or the quality of the server is not good< br />3 There is something wrong with your network settings< br />4 There's something wrong with your system< br />5 You're poisoned
first of all, check the lines at home to see if the connectors in the house are connected properly and if the lines pass through any interference sources, such as air conditioners, refrigerators, televisions, etc., so as to keep a certain distance from these electrical equipment. It can also replace the indoor lines with more anti-interference network cables. Make sure the wiring is connected correctly. After entering the home, the telephone line is connected to the junction box, and then separated to the voice separator, one line goes to the telephone, one line goes to the modem (the separator is marked). At the same time, ensure that the communication quality of the line is good without interference, and no other equipment that will cause line interference is connected. And check whether the junction box and crystal head have poor contact and whether they are wound in series with other wires. If possible, it's better to use standard telephone line and connect PC with twisted pair attached to ADSL modem. Line is one of the important factors for the quality of image access to the Internet. Signal interference sources such as radio transmitting tower, electric welding machine, tramcar or high-voltage power transformer within 100 meters from the user's cable can make the user offline receive clutter (copper clad steel wire has weak shielding and strong signal receiving ability), causing strong interference to the user's line. The interfered signal is usually the unshielded offline part, because the relay cable has a shielding layer, so the interference and influence are very small. If you use some shielded downlines in places with large interference, it will rece the speed instability or disconnection caused by interference. In addition, the power line should not be paralleled with the ADSL line, in order to avoid crosstalk, resulting in ADSL failure. In addition, there are many other factors that cause network instability, such as signal interference, software conflict. The mobile phone, which has a large radiation, must not be placed next to the ADSL modem, because the mobile phone will automatically find the network every few minutes. At this time, the strong electromagnetic interference is enough to cause the ADSL modem to cut off the current
Second, network cards are usually PCI network cards or on-board network cards. When choosing a better quality network card, it may cause poor quality of Internet access. 10m or 10m / 100M adaptive network card can be used. In addition, many machines share the Internet and use al network cards, which also causes conflicts, which is also worthy of attention. At this time, you should pull up the network card connecting to the LAN or other computers, and only use the network card connecting to ADSL to test the Internet. If the fault returns to normal, check whether there is any conflict between the two network cards
3. ADSL modem or network card setting problem. Now modem generally has two working modes, one is the normal mode of using dialing software, the other is the routing mode of automatic dialing. In normal mode, you don't need to set modem, just use the default mode. The routing mode needs to be set. Modem has its own flash memory, which can save the account and password box settings for automatic dialing. The most common method is to set the IP address of ADSL modem or DNS server incorrectly. Because for ADSL virtual dial-up users, there is no need to set the IP address, which can be automatically assigned. TCP / IP gateway generally does not need to be set. But set DNS must be set correctly, DNS address can be obtained from the local telecommunications department. In addition, TCP / IP settings are most likely to cause the situation of not being able to browse web pages. Generally, it is set to automatically obtain the IP address, but DNS must be filled in. Other default can be used
IV. ADSL modem synchronization abnormal problem, check whether your phone line and ADSL connection place are in poor contact, or there is a problem with the phone line, the poor quality of the phone is particularly easy to cause drop line, but such a problem is not easy to check, so be sure to use a good quality phone line. If it is suspected that the separator is broken or the ADSL modem is broken, try to directly connect the external line to the ADSL modem without using the separator. The connection between the separator and ADSL modem should not be too long, otherwise it cannot be synchronized. To eliminate the above situation, as long as the ADSL modem is restarted, the synchronization problem can be solved< In addition to the above-mentioned line conditions, there are also computer system problems. For example, the legendary killer caused the LAN to drop. This problem occurs in a large area all over the country. The virus will affect the Internet cafes (LAN) of host agent and router agent. Legend killer is a destructive software that can cheat LAN by ARP and create virtual gateway address to collect login information of Legend game in LAN and analyze it to get user information. Workflow: first of all, broadcast local Mac to LAN by ARP Cheating, so that the workstation in LAN mistakenly thinks this machine is gateway. This process will cause the connection between LAN and Internet to be interrupted, When the user restarts the game and logs in the account, the account information will not be uploaded to the proxy server directly through the gateway, but will be uploaded to the legendary killer software which is carrying out ARP deception, Attack situation: LAN and Internet link speed suddenly slows down or even breaks down. Online games break off the link, and after logging in again, the server will be prompted that there is no corresponding response. It is suggested to check and kill the virus first; If you have the ability, re install the system; If the machine has two network cards, unload one network card; It is suggested that users who are not familiar with computers should not install all kinds of firewall software at will.
