说明：  基于SVPWM的电压型三相整流仿真系统，包括SVPWM模块，以及电流环和电压环的建模(The simulation system of voltage source three-phase rectifier based on SVPWM includes SVPWM module, modeling of current loop and voltage loop)

节点度是指和该节点相关联的边的条数，又称关联度。 特别地，对于有向图， 节点的入度 是指进入该节点的边的条数; 节点的出度是指从该节点出发的边的条数。(Node degree refers to the number of edges associated with the node, also known as the degree of association. In particular, for a directed graph, The ingress of a node is the number of edges entering the node; The out-degree of a node is the number of edges that start from that node.)

分别对matlab和ansys两种平台的拓扑优化结果分析比较，为学习者提供了两种不同优化设计思路，过程详细清晰，易于学习理解(The analysis and comparison of topology optimization results between MATLAB and ANSYS two platforms provide two different optimization design ideas for learners. The process is clear and clear, and easy to learn and understand.)

说明：  焊接电弧的仿真模拟的能量源项C代码，用FLUENT建模，欢迎下载！(Welding arc simulation C code, using FLUENT modeling, welcome to download!)

基于SAR-ADC的DAC模块的电容切换，所做的动态功耗仿真，比较了不同切换模式的功耗。(Capacitance switching of DAC module based on SAR-ADC is simulated and power consumption of different switching modes is compared.)

本Matlab程序对需要高速穿越大气层的返回舱进行了纵向三自由度的模拟计算，只需输入如下基本参数，初始速度，再入高度，再入角。程序中有比较详细的说明。大气模型采用了真实的1976年美国标准大气模型，内附计算标准大气模型的Matlab程序，只需输入高度和高度间隔即可求出详细的参数值。(The Matlab program calculates the longitudinal three degrees of freedom of a reentry module that requires high speed passage through the atmosphere. Only basic parameters such as initial velocity, reentry height and reentry angle are entered. There are more detailed instructions in the program. The atmospheric model uses the real 1976 American Standard atmosphere model, which contains the Matlab program for calculating the standard atmospheric model. Only the input height and height interval can be used to find the detailed parameter values.)

说明：  该程序是大型有限元ADINA的源程序代码(This program is the source code of large finite element ADINA.)

说明：  混合粒子群求解TSP问题，重新定义了离散粒子群算法DPSO的速度和位置公式,使其适宜求解离散问题.针对DPSO易早熟,收敛慢的缺陷,建立局部极小区域的扰动机制,在结合局部搜索算法PSEC后,提出了一种混合离散粒子群算法HDPSO.(Hybrid particle swarm optimization for TSP)

说明：  用C语言将相变温度-压力曲线写入udf，用于fluent中自定义函数功能，添加于物性参数。(Phase Transition Temperature-Pressure Curve)
