"Quiet meaning": The original meaning of this word is quiet, and it is extended to appease and appease. Later generations often write "quiet". From the original meaning, it also means static, calm and harmonious. Phonetic characters. From the struggle, the green voice. Group words: silence, meditation, still life, stillness, meditation, stillness, exercise, quietness, quiet garden, meditation, static electricity and so on.
In the Western Zhou Dynasty, the phonetic symbol "Qing" of the word "Jing" was only in the upper left corner of the whole word. In the spring and autumn period, it has been established as a pattern of left and right tones. However, during the Warring States period, there was still a retro layout, which was found in Chu characters, and the phonetic symbol "Qing" was decorated with the shape of "mouth". Seal script inherits the writing method of Qin characters since the Spring and Autumn Period. After the official script was changed, the claw shape on the upper part of the "Zheng" symbol could be simplified into a-shape. In addition, the claw shape on the upper part of the "Zheng" symbol or the "Japanese" symbol was wrongly written in the Qin and Han Dynasties, so the later regular script was not used. There are two forms of regular script: static and static. According to the old and new font standards, those who contend prosper and those who contend perish. The original meaning is silence. It was extended to pacify and appease, and later generations wrote classics. Zhou Bangui: "Three years of quiet east or (country)." From the original meaning, it also means static, calm and quiet.
What are the methods to keep the static characteristics of the sensor stable?
The conclusion of calibrating the accuracy level of the instrument is that the performance goal of the pressure sensor is actually to determine the measurement accuracy of the pressure sensor, so the accuracy of the measuring instrument is at least one level higher than the calibration accuracy of the pressure sensor. In this way, the static performance and accuracy of the calibrated pressure sensor are reliable.
What is the way to calibrate the pressure sensor with static characteristics? To calibrate the static characteristics of the sensor, we must first create a static standard condition. Secondly, the accuracy of the selected and calibrated pressure sensor needs to be calibrated to some extent. Then, you can start calibrating the pressure sensor.
The calibration process is as follows: Firstly, the full range (measuring scale) of the pressure sensor is divided into several equidistant points.
Step 2, according to the range of the pressure sensor, gradually input the standard value from small to large, and record the output value corresponding to the input value.
Step 3: Delete the input values bit by bit from large to small, and record the output values corresponding to each input value together; According to the procedures described in the second step and the third step, the pressure sensor is repeatedly tested in positive and negative reciprocating cycles, and the obtained output is input into the test data list or drawn into a curve; Finally, it is necessary to process the test data, and according to the processing results, the static characteristics of the pressure sensor, such as linearity, sensitivity, lag and repeatability, can be obtained.
The target program generated by the compiler must be an executable program?
Not necessarily. Before generating executable files, you need to compile and link the source code.
The general order is this: precompile, compile, assemble, link! You cannot generate an executable file without a link! The object file generated by assembler cannot be executed immediately, and there may be many problems unsolved.
The main job of linker is to connect related target files with each other, that is, to connect the symbol referenced in one file with the definition of the symbol in another file, so that all these target files become a unified whole, which can be loaded and executed by the operating system.
According to the different linking methods with library functions specified by developers, linking processing can be divided into two types:
(1) static link
In this way, the code of the function will be copied from its local static link library to the final executable program. In this way, when the program is executed, these codes will be loaded into the virtual address space of the process. Static link library is actually a collection of target files, and each target file contains the code of one or a group of related functions in the library.
(2) Dynamic link
In this way, the code of the function is put into an object file called dynamic link library or shared object. What the linker does at this time is to record the name of the * * * enjoyment object and other small amount of registration information in the final executable program. When this executable file is executed, all the contents of the dynamic link library will be mapped to the virtual address space of the corresponding process at runtime. The dynamic linking program will find the corresponding function code according to the information recorded in the executable program.
For function calls in executable files, you can use dynamic linking or static linking respectively. Using dynamic link can make the final executable file shorter, and when the * * * shared object is used by multiple processes, it can save some memory, because only one code of this * * * shared object needs to be saved in memory. However, using dynamic links is not necessarily better than using static links. In some cases, dynamic linking may bring some performance damage.

What is the goal of visualization technology?
1, faster
It is much easier for the human brain to process visual information than written information. Summarizing complex data with charts can ensure that the understanding of relationships is faster than those messy reports or spreadsheets. This provides a very clear way of communication, enabling business leaders to understand and process their information more quickly. Big data visualization tools can provide real-time information, making it easier for stakeholders to evaluate the whole enterprise. The rapid adjustment of market changes and the rapid identification of new opportunities are the competitive advantages of every industry.
2. Provide results in a constructive way.
Many business reports submitted to senior managers are standardized documents, which are often exaggerated by static tables and various chart types. It is precisely because it is too detailed that those executives can't remember these contents, so they don't need to read too detailed information. However, statistical reports from big data visualization tools enable us to reflect those complex information with some short charts, and even a single chart can do the same. Decision makers can make use of interactive elements, such as heat map, fever, etc.
Charts and other new visualization tools can easily explain various data sources. Rich but meaningful graphics help busy executives and business partners understand problems and pending plans.
3. Understand the connection between operation and result.
One of the benefits of big data visualization is that it allows users to track the relationship between operations and overall business performance. In a competitive environment, it is very important to find the correlation between business functions and market performance.
What should I do if I accidentally electrostatic the network?
1. First, turn on the WIFI switch of your mobile phone and connect the target WIFI.
2. Return to the phone desktop, and then click Settings.
3. Open the settings page and select the WLAN option.
4. At this point, display the connected WIFI name, and click the arrow on the right.
5. Static IP is turned off by default, and the lower part is also in a gray unset state. Click the switch to turn it on.
Really no, we can only restore the factory settings!
