说明：  通过设置不同的参数，生成BA无标度网络。(This progarm is to create a BA network by setting different parameters.)

说明：  这是基于蚁群算法的无人机uav巡检实例程序，平台为matlab。(This is an example program of UAV path planning based on ant colony algorithm, which contains all the source code and the platform is matlab)

说明：  非线性调频信号的产生函数，以及绘制时域频域图像(Proudce a NLFM signal,use for radar test)

abaqus 使用技巧-Inp文件中单元类型改变时，一定要注意，划分网格的时候是否，选用了一种望各类型，比如4变形和3变形的区别，如果用注意将所有的单元类型都做相应的修改。这说明单元类型由2个因素决定，1网格形状，2计算任务.(Abaqus tips-When changing the unit type in the Inp file, be sure to pay attention to whether or not to select a type, such as 4 deformation and 3 deformation, if you use the attention, all the unit types should be modified accordingly. This shows that the unit type is determined by two factors, 1 grid shape, 2 calculation tasks.)

说明：  周期边界，通过python代码实现，abaqus多尺度仿真，有效性能计算，复合材料(Periodic boundary, implemented by Python code, ABAQUS multi-scale simulation, effective performance calculation, composite materials)

matlab仿真程序，可以直接运行，是分数阶混沌研究的有效资料(Matlab simulation program, which can run directly, is an effective data of fractional chaos research)

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.)

高频高压开关电源，采用LLC软开关技术，多用于静电除尘领域(high frequency high voltage switch power supply)

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)
