说明：  计算6个数字的AC值，您通过键盘输入6个整数，程序将会帮你计算出AC值(Calculate the acvalue of 6 numbers)

java 结构模式，装饰模式，不断增加类的功能，而不使用继承，包括例子。-java model, decorative patterns, the growing category of functional without the use of inheritance, including examples.

这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible). The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot). The s

shearlet变换工具箱，官方网站上下载，分享给大家使用(Shearlet transformation toolbox, download from the official website, share it for everyone to use)

说明：  AUTOGRAM频带选择的原始程序，可用其进行故障频带的选择(The original program of autogram frequency band selection, which can be used to select the failure frequency band)

说明：  在Linux系统下读取惯导数据，输出姿态角（横滚角、俯仰角、偏航角）(Reading inertial navigation data under Linux system, output attitude angle (roll angle, pitch angle, yaw angle))

VSC-hvdc，基于Matlab Simulink平台搭建的电压源型高压直流输电系统，又称柔性直流输电系统，用于电路仿真，电网放着 ，MATLAB 柔性直流输电程序，可以加入风电场。单机无穷大系统。(VSC-hvdc,This procedure is based on Matlab Simulink platform to build the voltage source HVDC transmission system, also known as flexible DC transmission system.)

说明：  一、多少鸡汤文都比不上一张钞票给的安全感。少一点矫情，多一点努力。你想过的那种生活，得自己去挣。 二、考虑一千次，不如去做一次；犹豫一万次，不如实践一次；华丽的跌倒，胜过无谓的彷徨，将来的你，一定会感谢现在奋斗的你。 三、后来才明白，要赚到足够令自己安心的钱，才能过上简单、安逸、自由的生活，才能让自己活得更有底气。所以，多花时间努力，少点功夫矫情。 四、所有成功的背后，都是苦苦堆积的坚持；所有人前的风光，都是背后傻傻的不放弃。只要你愿意，并为之坚持，总有一天，你会活成自己喜欢的模样！ 五、前行的路，不怕万人阻挡，只怕自己投降；人生的帆，不怕狂风巨浪，只怕自己没胆量！有路，就大胆去走；有梦，就大胆飞翔。(First, how many chicken soups are less secure than a banknote. A little bit of love, a little more effort. The kind of life you have thought of, you have to earn yourself. Second, consider a thousand times, it is better to do it once; hesitate 10,000 times, it is better to practice once; gorgeous fall is better than unnecessary, and you will definitely thank you for your struggle in the future. Third, I later realized that to earn enough money to reassure you, you can live a simple, comfortable, and free life in order to make yourself more confident. Therefore, spend more time and effort, less effort.)

说明：  可以计算固定共振腔高度的互阻抗，超材料研究(Calculate acoustic impedance with fixed height)
