the integrated motherboard of your graphics card should have its own CD
put it into the computer and then install the driver of the graphics card.
if it's a CD-ROM, you can install it.
if you don't have a CD-ROM, you have to load it. Go to the driver's home and have a look http://www.mydrivers.com/
this is a better website in China. There are many drivers such as sound card, network card and graphics card. You'd better download a driver wizard. It's very convenient to backup and update the driver. You don't have to find it yourself. This is a better website in China. Of course, you can't use windows optimization master or other software
the curve is calibrated by Jack and pressure gauge, and calculated by interpolation method or regression equation
you take the jack and pressure gauge for tension to calibrate first (it is OK for engineering inspection institutions in general provinces and cities),
then according to the regression equation given after calibration, which is generally the equation of force and pressure, the reverse pressure is OK
if you can't calculate the calibration curve, you can put the calibration curve or table up to help you calculate.
Graphics card needs driver
by installing the driver, the system can correctly recognize the graphics display card, render 2D / 3D, and give full play to the performance of the display card
it is equivalent to the interface of hardware. The operating system can only control the work of hardware devices through this interface. If the driver of a device is not installed correctly, it will not work normally
for this reason, the driver plays a very important role in the system. Generally, after the operating system is installed, the first thing is to install the hardware device driver
extended materials:
driver is a part of hardware, when installing new hardware, driver is an indispensable important component. Whenever you install a hardware device that does not belong to your computer, the system will ask you to install the driver
the new hardware is connected with the computer system, and the driver plays the role of communication, telling the computer system the function of the hardware, and also conveying the instructions of the system to the hardware, so that it can start to work
It's not the same thing. In engineering, the bolt needs to detect the torque force, and the anchor cable needs to detect the preload
as a tension member deep into the stratum, one end of the anchor is connected with the engineering structure, and the other end is deep into the stratum. The whole anchor is divided into free section and anchorage section. The free section refers to the area where the tension at the anchor head is transmitted to the anchor solid, and its function is to impose prestress on the anchor
the anchor cable is fixed on the slope through the outer end, and the other end is anchored in the stable rock mass within the sliding surface. The prestressed steel strand passing through the sliding surface of the slope directly proces the anti sliding resistance on the sliding surface, increases the anti sliding friction resistance, and makes the structural surface in a compressed state, so as to improve the integrity of the slope rock mass
From the mechanical point of view, it mainly improves the cohesion c and internal friction angle of surrounding rock mass φ The anchor rod is located in the rock and soil body and forms a new complex with the rock and soil body. The bolt in the complex is the key to solve the problem of low tensile capacity of surrounding rock mass. So the bearing capacity of rock and soil is greatly strengthened Bolt is the most basic component of roadway support in contemporary underground mining. It binds the surrounding rock of roadway together to support itself Anchor rod is not only used in mine, but also in engineering technology to reinforce slope, tunnel and damIf you need to install the driver, the specific installation method is:
1. First, open the network, search the driver life, and click to open the official website
