说明：  在abaqus中可以实现零厚度的cohesive插入(Implementing cohesive insertion with zero thickness)

说明：  lm求解非线性方程组(Solving nonlinear equations by LM)

滑模变结构 刘金坤 ，很好用，很实用，特别是机器人控制方向。(sliding mode control liujinkun)

直流配网模型，非常基础的直流配网模型，便于对直流配网的基本掌握和学习(DC distribution network model, very basic DC distribution network model, easy to grasp and learn the basic DC distribution network)

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.)

粒子群算法的仿真程序，并采用典型benchmark进行演示分析； 然后，应用粒子群算法进行热工过程水轮机系统模型辨识，matlab软件可直接运行； 采用粒子群算法与PID参数整定进行联合仿真，用以提高PID控制器对热工过程水轮机的控制性能。(Particle swarm algorithm simulation program, and the use of a typical benchmark for demonstration analysis; Then, the particle swarm optimization algorithm is used to identify the turbine system model of the thermal process. The matlab software can be run directly. Particle swarm algorithm and PID parameter tuning are used to simulate the PID controller to improve the control performance of the hydraulic turbine.)

逆流套管式换热器仿真小程序，工质物性调用refprop,所以需要自行嵌套refprop(Counter flow sleeve heat exchanger simulation small program, physical properties call RefProp, so need to self nest RefProp)

说明：  abaqus经纬编织织物模型，umat子程序(ABAQUS warp and weft knitted fabric model, UMAT subroutine)
