说明：  matlab生成一个随机相位屏，可以模拟大气和电离层，结果为彩色图。(Matlab generates a random phase screen, which can simulate the atmosphere and the ionosphere. The result is a color map.)

在文件qiexian.m中输入两个摩尔圆的坐标即可画出莫尔圆，并求出两圆的切线(In the file qiexian.m, enter the moire circle with the coordinates of two Moore circles, you can find the tangent of the two circle.)

说明：  双向渐进优化法（beso）在MATLAB平台的实现，编写inp文件，并运行(The realization of bidirectional progressive optimization method in MATLAB platform)

该软件是针对地下导线测量的改进方法设计的，即不必在地下对全站仪进行精确的点下对中，在全站仪上安装一个偏心测量盘，通过对实际测量结果进行归化改正，从而得到理论正确的测量结果。该软件需要用户输入指定参数，如偏心距e，实际测量角度β，实际测量距离L等，从而计算出理论测量角度α和理论测量距离S(The software is designed according to the improved method of underground traverse survey, which do not have the exact point of total station in the underground, the installation of a disc eccentricity measurement by total station, based on the actual measurement results are correct so as to obtain the measurement result of domestication, correct theory. The software requires the user to input the specified parameters, such as the eccentricity e, the actual measurement angle beta, the actual measurement distance L, etc., so as to calculate the theoretical measurement angle alpha and the theoretical measurement distance S)

Abaqus子程序，GTN孔洞损伤模型， 用于材料的损伤模拟(Abaqus subroutine, GTN hole damage model)

说明：  采用相场方法，计算合金中枝晶生长，标记为相场模型C_alloy。(Dendrite growth in the alloy was calculated by phase field method and marked as phase field model C_alloy.)

石崇老师编的PFC建立不规则边坡模型的代码(Code for establishing irregular slope model by PFC compiled by Shi Chong)

异步电机的VVVF的变频启动，含matlab仿真模型和编程M文件(AsynchronousMotor ,VVVF,including M file and SIMULINK model)

迭代计算算法，能够完成收敛分析，求解非线性方程根的一个很有效的方法。(Iterative algorithm can complete convergence analysis and solve the roots of non-linear equations.)

说明：  文件管理模块实现,还不错大家可以看看啊啊啊啊啊啊啊啊啊啊啊啊啊(啊)
