We should often use neutral liquid and soft cloth to wipe the screen, and then dry with a soft dry cloth. Get into the habit of not pointing the screen with your finger.

After some toss, finally done! Finally, the keyboard, mouse, speakers, microphones, monitors, power cords, telephone lines and other external lines are inserted into the chassis back panel of the socket. Many beginners in the process of assembling a computer, facing the chassis on the back of the various interfaces feel overwhelmed. However, I believe that after reading the following article, not only can understand the various interfaces on the back
backup and fault tolerance functions to ensure that the system can run normally under any circumstances, otherwise it will cause huge losses to banks and users; high system flexibility is required because of the nature of the work in the financial industry, which makes it difficult for a single information network to meet the requirements. Different departments must have different network types depending on their work nature, in order to meet their different needs, and even the Needs of the sam

With the development of China's routing industry, we have also promoted the update and upgrade of the wireless router technology. Here we mainly analyze the wireless router setting skills. With the promotion of ISPs such as China Telecom, wireless ADSL cat is widely used in many households, SOHO and office users. Wireless ADSL cats are increasingly exposed to security factors while facilitating the establishment of users' networks. This is because many users have adopted the default factory wire
Simple reflection, simple reflection
After thinking about the simple reflection, I found some information on the Internet and some code, which is roughly as follows:
public static void PrintProperties
What are the differences between simple reflection and complex reflection?
Hand scaling reflection, blinking reflection, urination reflection, knee hop reflection, and so on are all simple reflection from life. In this type of reflection, as long as there is stimulation, the normal human body wil
Next we searched for the pitch.
The self-correlation method is used to search for the pitch period.
Calculate the number of a ^ 2 + B ^ 2> 2AB according to the number of keys.
We can know that the self-correlation value of a voice signal will reach the maximum value at its pitch.
(There is also a pitch estimation method, called the short-term average amplitude difference method. Unlike the self-correlation method, it is in the pitch, which is a valley value)

width of each pixel is small, they are much larger than the point or line width defined in mathematics. When OpenGL is used for computation, although a series of floating point values are used to define the vertex string, each vertex is still displayed in a single pixel, which is just an approximate fit.
Ii. Point)
Vertex is a vertex represented by a floating point value ). 3D coordinates (x, y, z) are used for processing all vertices in OpenGL internal computation. point defined by 2D coordi
The Design of printed circuit board is very important for the anti-interference ability of single chip microcomputer system. The printed circuit board and wiring should be designed based on the three principles of minimizing noise sources, minimizing noise propagation and coupling, and minimizing noise absorption.The printed circuit board should be reasonably partitioned. The single-chip microcomputer system can be divided into three zones, namely, the analog zone (for fear of interference), the

Magnetic beads do not match when the frequency is uncertain or unpredictable. the capacitor is separated directly, causing float. the inductance is large in size, with many stray parameters and unstable. 0 euro resistance is equivalent to a very narrow current path, which can effectively limit the Loop Current and suppress noise. Resistance degrades in all frequencies (0 euro r

The zero-euro resistance has the following functions:
A resistance with a resistance value of 0 ohm is called a 0 euro resistance.
First of all, we should understand that 0 euro resistance is only available in ideal conditions. In reality, it does not exist. Only the resistance of 0 euro is as close as possible.
0 euro resistance has the following functions:

connect the corresponding line according to the above definition. In fact, the 5pin and 6pin, 9pin, and 10pin are connected by a single wire in some chassis, and the same effect can be achieved.It seems that there are a lot of lines, but it is also very easy to remember, you may wish to follow the instructions I remember. First remember the first three, the first is the microphone input, the second is the ground, the third is the microphone voltage, then the 5pin and 6pin into the right channel
permeability of the core is high. Therefore, the inductance is large, and the electromagnetic interference is restrained by reflection, in this case, the core loss is small, and the entire device isLow-loss, high-Q-characterized inductor, which may cause resonance in the low-frequency segment, and sometimes may cause interference enhancement after the use of ferrite magnetic beads.In the high-frequency band, the impedance is composed of resistance components. As the frequency increases, the mag
simulator for this function is not very good. Therefore, jlinkv8 selects Gnd only for the target board, but not for VCC. Therefore, I think this mode is the most reasonable. Of course, there is no error in the total Gnd and VCC between the simulator and the target board.
