There are many BOT projects in the standard sense, but BT projects similar to BOT projects are rare
defects of BT Investment Mode
BT project construction cost is too large. The adoption of BT mode must go through the stages of project determination, project preparation, bidding, negotiation, signing contract related to BT, and handover. It involves many links such as government permission, examination and approval, and foreign exchange guarantee. It involves a wide range, strong complexity, difficult operation, many obstacles, and difficult implementation. The most important thing is that the financing cost is also increased e to many intermediate links
BT financing regulation is difficult. Due to the particularity of BT legal nature, the complexity of legal relationship and the combination of contracts, it is difficult to supervise BT financing
the subcontracting of BT project is serious. In BT mode, the government only has direct contact with the general contractor of the project, so it is suggested that the project enterprise should be responsible for the implementation. Therefore, the implementation of the project may be refined, and the subcontracting of construction projects will become more and more serious
BT project quality cannot be guaranteed. In BT project, although the government stipulates to urge and assist investors to establish a three-level quality assurance system, apply for government quality supervision, improve various management systems, and do a good job in safety proction. However, for the benefit of investors, there are problems in the construction standards, construction content, construction progress of BT project, and the construction quality can not be guaranteed
how to solve the defects of BT Investment Mode
in the face of these defects, the control ability of local governments is relatively poor. In the process of government BT investment construction project transition from planned economy to market economy, there are still some closed operation of project management in relevant government departments to varying degrees, sometimes even in violation of construction proceres. In the process of the construction and implementation of specific projects, there are also some problems to varying degrees, such as ineffective audit of project functions and schemes, no distinction between government and enterprises, lack of professional and technical personnel, extensive management, local monopoly and local protection, lack of competition, and even "Rent-seeking" corruption. In fact, it is easy to find that BT projects of some local governments have not been handled in accordance with the existing laws and policies on bidding and government franchise
it is urgent to improve BT Investment
in addition to improving BT operation mechanism and strengthening government supervision over BT projects, it is also very important to establish BT risk response mechanism, determine risk types and formulate corresponding risk avoidance countermeasures. In addition, the government should consider the introction of independent third-party intermediary services. At present, famous investment engineering consulting and design institutions at home and abroad have strong BT investment expertise and skills, such as China International Engineering Consulting Company. In terms of financing and capital operation, securities companies or famous investment consulting companies can be employed to serve them
as BT was born in China for a short time with little experience, it is a new thing. Therefore, the most basic and important thing is to have a clear legal protection of the contract. At the same time, in terms of management, the government power should be determined by law for the determination of the project investment budget, design scheme, project quality inspection and financial audit. But at present, there is no special legislation on BT in China, so we should speed up the pace of legislation.
BT is a kind of investment mode that the government uses non-governmental funds to undertake some infrastructure projects. BT is the abbreviation of "build" and "transfer", which means that the government grants an infrastructure project to an enterprise legal person for investment through a contract, and the enterprise legal person is responsible for the investment, financing and construction of the project within a specified period of time. At the end of the construction period, the government purchases the project from the enterprise legal person according to the principle of equal compensation
BOT is the abbreviation of Build Operate Transfer, which is usually translated as "Build Operate Transfer". This translation is straightforward, but it can't reflect the essence of BOT. BOT is essentially a way of infrastructure investment, construction and operation. On the premise of an agreement between the government and the private sector, the government issues a license to the private sector to allow it to raise funds to build an infrastructure and manage and operate the infrastructure and its corresponding procts and services within a certain period of time
the biggest feature of this method is to mortgage the operation right of infrastructure for a period of time in order to obtain project financing, or privatization of infrastructure state-owned projects. In this mode, firstly, the project sponsor obtains the franchise of a project from the client through bidding, and then forms a project company, which is responsible for financing the project and organizing the construction of the project
manage the operation of the project, recover the fund to repay the loan through the development and operation of the project and other preferential treatment given by the local ZF ring the concession period, and obtain reasonable profits. After the concession period, the project shall be handed over to ZF free of charge. In BOT mode, investors generally require ZF to guarantee its minimum rate of return. If ZF fails to meet the standard ring the concession period, ZF should give special compensation
according to Article 2 of the government procurement law of the people's Republic of China, "government procurement refers to the use of financial funds by state organs, institutions and organizations at all levels to purchase goods, projects and services within the centralized procurement catalogue formulated according to law or above the quota standard."
according to Article 7 of Chapter 4 of the guiding opinions on the cultivation and development of EPC and project management enterprises [2003] No. 30 issued by the Ministry of construction of the people's Republic of China, "EPC enterprises with investment and financing capacity are encouraged to carry out construction transfer (BT), construction operation transfer (BOT), construction ownership operation (BOO) according to the requirements of owners for qualified projects It is organized and implemented by means of construction, ownership, operation and transfer. "
BT is a kind of Internet P2P transmission protocol, full name "BitTorrent", Chinese name "bitstream", has developed into an open transmission protocol with a large number of developers. BT download is realized through a P2P download software, which has the characteristics that the more people download, the faster the download speed
bit torrent protocol: commonly known as bit torrent and BT download. Program for network protocol of file sharing in peer-to-peer network. BitTorrent is specially designed for the sharing of large capacity files. It adopts a kind of MLM like working mode
extended data
BT first divides a file into many parts on the uploader side, user a downloads some of them randomly, while user B downloads others randomly
in this way, a's BT will go to B's computer to get the downloaded part according to the situation (the fastest end will be automatically selected according to the speed of network connection with different computers), and B's BT will go to a's computer to get the downloaded part according to the situation, which not only reces the load of the server, but also speeds up the download speed of both sides
in fact, every user is uploading as a source while downloading (someone else takes a part of that file from the computer). In this case, the uplink bandwidth is effectively utilized, and the bottleneck of traditional FTP is avoided. The more people join in the download, the more people actually upload, and the faster other users download. The advantages of BT are reflected here< br />

the first explanation is as follows:
BT is a popular P2P file sharing tool recently, and its core protocol is also called BT
BT is considered to be especially suitable for the sharing and downloading of large-scale media files because it adopts the multi-objective sharing and downloading mode, which makes the download speed of the client continuously improve with the increase of the number of download users. In addition, because the download protocol of BT stipulates that the download priority of the client is related to the traffic of the shared data provided by it, BT protocol can curb the free rider phenomenon widely existing in P2P system to a certain extent
"seed" is the name of the first source file, which refers to the complete file file link on the P2P platform, through which other users can automatically find the computer providing file download and download

BT related news:
the world's first criminal prosecution case of illegally distributing movie programs with BT "Point-to-point software". The defendant Chen Naiming was convicted of three counts of violating the Copyright Ordinance in Tuen Mun magistracy yesterday, The probationary defendant was released on l of 5000 yuan in cash and his sentence was postponed until November 7. The judge made no secret that he might be sentenced to imprisonment. According to the law, the maximum penalty for the offence is a fine of $50000 and four years' imprisonment for each infringing . The charges allege that Chen Naiming released films on the Internet three times on January 10 and 11 this year, including "night demon", "universe panic" and "beauty pageant undercover". The judge said that when the defendant distributed the film, 30-40 people participated in the download, and they would not buy the genuine CD after downloading. Therefore, the defendant's behavior did cause sales losses to the right owners and losses to the film rental market, which constituted the intention to benefit others from dishonesty, because the defendant has convicted three crimes against the Copyright Ordinance. It is reported that since the disclosure of the case, online infringement activities have decreased by 80%. So far, no one has released the source documents. At present, only about 10 news groups in Hong Kong allow Internet users to download files through BT

BT software uses multithreading to download and upload at the same time, resulting in a large amount of data throughput on the hard disk. When a file is downloaded by n people, the hard disk will bear one download and N-1 upload (that is, the upload action by BT), so the load of the hard disk will be greatly increased, and the probability of damage will also be greatly increased< Some tips to rece the damage are as follows:
1. Change the hard disk cache
you can rece the damage of BT download to the hard disk by modifying the cache of the hard disk. The specific operations are as follows:
1. Modify the registry, change the hard disk cache
(1) open "start → run" in turn, and enter "regedit" to open the registry, Expand to the following key values in turn: HKEY_ LOCAL_ MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Session Manager\ Memory Management
(2) here, check whether there is a key value of "iopagelocklimit". If not, you can create a new DWORD value (double byte value). You need to enter a hexadecimal number here. Windows only has 512KB cache by default, which is obviously not enough. If the memory is more than 256MB, opening up some cache can rece hard disk read-write and improve performance. Generally, 8-16mb is the best. 16m corresponds to 4000, 32m corresponds to 8000, if the memory is large, set it larger
prompt:
calculation conversion method is as follows:
1MB = 1024k,
16MB = 16384k
= 4000 (hexadecimal)
= 4 * 16 ^ 3 + 0 * 16 ^ 2 + 0 * 16 ^ 1 + 0 * 16 ^ 0 = 16384k (decimal)
(3) finally, restart the computer
2. Setting BT software to change the hard disk cache
the method of modifying the registry may be troublesome for those who are not familiar with the registry, and they dare not do it easily. In fact, we can also download software in BT, through the graphical interface to set the hard disk cache. At present, the mainstream BT download software has the setting item of adjusting the cache. Here we take BitComet as an example
in the open main interface, you can open the main menu "options → options" in turn, and click the "disk cache" option in the open main interface to set the minimum and maximum values of disk cache in the right window. If the download speed is always kept at 500kb / s, you can set the disk cache size to 40m, Of course, you can also check "automatically adjust the cache size within the maximum and minimum range" to let the program automatically adjust the disk cache. It's much easier to set in BT software. You don't need to remember the sub key of the registry, just input the value to be set directly< Second, rece the priority of BT software
BT takes up more resources, which may affect the performance of the whole system. If we are using Windows 2000 / XP system, we can use task manager to rece the priority of BT software, so that even if it occupies resources, it will not affect the performance of other applications, because the priority of preempting resources is not high enough, so as to rece the impact on hard disk and system. The specific operation is as follows:
in Windows XP operating system, you can press the "Ctrl + Alt + Del" combination key to open the "Windows Task Manager" of the system, and click the "process" tab to find the corresponding BT download program; Then right-click it and set the "set priority" on the right-click menu to "below standard" or "low"
through the above methods, we have reced the damage of BT download to "0". As long as you don't open too many download or upload windows at one time (usually 1 to 3), you can download BT safely
friendly tips
in fact, the high temperature of the hard disk is caused by the high-speed rotation of the hard disk and the friction between the hard disk and the air. In fact, the heat of reading and writing is very small. Even if you don't use BT, if you run the computer for a long time, listen to music and play 3D games, it will also be a hard disk. And the faster the speed of the hard disk, the higher the temperature. This is the operation problem of the hardware itself, and has nothing to do with the software. Therefore, instead of using BT to protect the hard disk, it is more practical to improve the ventilation state of the chassis
the problem of repeated reading and writing does exist. Some people describe BT as putting two or three times of losses together. A lot of reading and writing will greatly accelerate the consumption of hard disk and rece the life of hard disk. Although this statement is reasonable, it is too exaggerated. In fact, it's not only bt that will increase the number of repeated reads and writes. Bad habits will not consume less hard disk than BT. By increasing the read and write buffer of BT program, the read and write times of BT can be greatly reced, and the consumption of hard disk can be reced. And correcting bad habits of hard disk can increase the life of hard disk. Therefore, as long as the adjustment is appropriate, the repeated read-write operation of BT will not consume the life of the hard disk
the situation of sector fault block is similar. There is no denying that the download of BT will proce a lot of blocks, but any computer that has been operating for a period of time will have a lot of blocks. The block itself is only a record of a sector, and will not affect the hard disk. The reason that multiple blocks will damage the hard disk is that every time a program or file is executed, it is necessary to
