说明：  采用simulink搭建IEEE标准33节点仿真模型及.m程序(IEEE standard 33 node simulation model)

本程序是完成网络的评价路径长度和聚类系数的计算。(This program is to calculate the average path length and clustering coeffient of a network.)

说明：  针对带储能的光伏系统出力不稳定问题，基于储能变流器提出了一种带有灰色补偿的Back-stepping控制方法，以实现对并网点上层规划层面有功功率P和无功功率Q指令的跟踪控制，同时保证并网点电压的 稳定。(Aiming at the problem of output instability of photovoltaic system with energy storage, a back stepping control method with gray compensation is proposed based on energy storage converter to realize the tracking control of active power P and reactive power Q command at the upper planning level of the parallel network, and to ensure the stability of the voltage of the parallel network.)

说明：  薄壁圆柱壳轴压屈曲非线性计算，采用模态缺陷作为初始缺陷(In the nonlinear calculation of thin-walled cylindrical shells under axial compression, modal defects are used as initial defects)

说明：  MATLAB OFDM仿真代码，采用QPSK调制(MATLAB OFDM simulation code, using QPSK modulation)

说明：  3维hashin失效准则~复合材料层合板(3-D Hashin Failure Criterion ~Composite Laminates)

说明：  生成三维随机纤维的matlba程序，可以直接使用(The matlba program for generating 3D random fibers can be used directly)

通过PYTHON修改inp文件进行全局插入零厚度cohsive单元(Modify the InP file through PYTHON to insert zero thickness cohsive unit globally.)

说明：  tarjan算法求解有向图中的简单环，非常好用(Tarjan algorithm is very useful for solving simple rings in directed graphs.)
