Go to the reproductive center When do you go

1. Through systematic examination, the reproctive medicine center will customize the exclusive fertility solution according to the situation of each couple. Specifically, couples need to register first, then go to the female or male outpatient clinic, and then provide medical history, follow the doctor's advice to do the relevant examination, so that the doctor can make a clear cause of infertility, and finally the doctor can make a correct diagnosis and give the treatment plan. If the patient's treatment plan is assisted reproctive and pregnancy treatment, then before treatment, both husband and wife need to provide the original and of ID card and marriage certificate.

2. Few news newspapers are national. People's daily and Guangming Daily are national. For example, Huashang daily, Yangzi Evening News and Yangcheng Evening News are very famous local newspapers
there are more professional newspapers nationwide, such as operator newspaper, consumer newspaper, electronic professional newspaper, military newspaper and so on.

3. bitcoin is the ancestor of all virtual currencies, with the highest price and value among all known digital currencies. But for the new people who lack experience and technology, mining is becoming more and more difficult, and simply speculation bitcoin is also a big risk. Another operation method and profit model (I personally test, extremely low risk, stable income, practical) may allow you to better control bitcoin

4. Hello, if you check now. The best is in menstruation after the end of more than five days can be. And you can't stay in the same room before the examination.

5. Check what, if it is check blood can't eat, if it is check pregnancy, can eat

PCI slot is the

PCI interface of fixed electronic devices, which is the abbreviation of peripheral component interconnect standard. It is the most widely used interface in personal computer

at present, almost all motherboard procts have this PCI interface slot, and PCI slot is also the slot type with the largest number of motherboards. At present, the popular desktop motherboard, ATX motherboard generally has 5 ~ 6 PCI slots, while the smaller mATX motherboard also has 2 ~ 3 PCI slots, which shows its wide application prospects

PCI bus is a tree structure independent of CPU bus. It can work in parallel with CPU bus. PCI devices and PCI bridges can be connected to PCI bus. Only one PCI master device is allowed on PCI bus, and all other devices are PCI slave devices. In addition, read and write operations can only be performed between master and slave devices. The data exchange between the slave devices needs to be transmitted through the master device

extended data:

main performance

1, high transmission rate, the maximum data transmission rate is 132mb / s, when the data width is upgraded to 64 bits, the data transmission rate can reach 264mb / s. This is unmatched by other buses. It greatly eases the bottleneck of data I / O, makes the function of high-performance CPU fully play, and meets the needs of high-speed device data transmission

PCI bus can make multiple buses coexist in one system and accommodate different speed devices to work together. Through the host-pci bridge mole chip, the CPU bus and PCI bus are bridged; PCI bus and ISA / EISA bus are bridged by PCI-ISA / EISA bridge mole chip to form a hierarchical multi bus system

high speed devices are removed from ISA / EISA bus and moved to PCI bus. Low speed devices can still be attached to ISA / EISA bus, inheriting the original resources and expanding the compatibility of the system

Independent of CPU, PCI bus is not attached to a specific processor, that is, PCI Bus supports a variety of processors and new processors to be developed in the future

Automatic identification and configuration of peripherals are convenient for users

5. Parallel operation ability

7. PCI slot is an expansion slot based on PCI local bus (peripheral component expansion interface). Its color is generally milky white, which is located below the AGP slot and above the ISA slot on the motherboard. Its bit width is 32-bit or 64 bit, its working frequency is 33 MHz, and its maximum data transmission rate is 133 MB / sec (32-bit) and 266 MB / sec (64 bit). It can plug in graphics card, sound card, network card, built-in modem, built-in adslmodem, USB2.0 card, IEEE1394 card, IDE interface card, raid card, TV card, video capture card and other kinds of expansion cards

PCI slot is the main expansion slot of the motherboard. By inserting different expansion cards, you can get almost all the functions that the computer can achieve. It is a veritable "universal" expansion slot

a standard introced by Intel Corporation in 1991 for defining local bus. This standard allows up to 10 PCI compliant expansion cards to be installed in a computer. PCI bus was first proposed to work at 33MHz frequency, and its transmission bandwidth reached 133mb / S (33MHz * 32bit / s), which basically met the development needs of the processor at that time. With the demand for higher performance, a 64bit PCI bus was proposed in 1993, and then the frequency of PCI bus was raised to 66MHz. The 32-bit and 33 MHz PCI bus is widely used, and the 64 bit PCI slot is more used in server procts. From the structure point of view, PCI is a primary bus inserted between CPU and original system bus. A bridge circuit is used to manage this layer and realize the interface between the upper and lower to coordinate the data transmission. The manager provides signal buffer and can maintain high performance at high clock frequency. It is suitable to provide connection interface for video card, sound card, network card, modem and other devices. The working frequency is 33MHz / 66MHz

PCI bus system requires a PCI control card, which must be installed in a PCI slot. This kind of slot is the type with the largest number of slots on the motherboard. On the current popular desktop motherboard, ATX motherboard generally has 5-6 PCI slots, while the smaller mATX motherboard also has 2-3 PCI slots. According to the different ways of implementation, PCI controller can exchange 32-bit or 64 bit data with CPU at one time. It allows intelligent PCI auxiliary adapter to perform tasks in parallel with CPU by using a bus master technology. PCI allows multiplexing technology, which allows more than one electronic signal to exist on the bus at the same time

development process

because PCI bus only has 133mb / s bandwidth, it is more than enough for most input / output devices such as sound card, network card and video card, but it can not meet the needs of increasingly powerful graphics card. Intel officially announced the third generation I / O technology to replace PCI bus on IDF in the spring of 2001. The specification is formulated by AWG (Arapahoe Working Group) supported by Intel. On April 17, 2002, AWG officially announced that the draft 3gio1.0 specification was completed and handed over to pci-sig (PCI special interest group) for review. At the beginning, we all thought it would be named serialpci (affected by serial ATA), but at the end, it was officially named pciexpress, which means high-speed, especially fast

On July 23, 2002, pci-sig officially announced pciexpress1.0 specification, and in early 2007, pciexpress2.0 specification (spec2.0) was launched, which increased the transmission rate from 2.5gb/s to 5gb/s; Mainstream graphics interfaces support pci-e2.0
