说明：  平面用cohesive单元模拟仿真裂纹扩展和结构失效，裂纹扩展(Plane simulation of crack growth and structure failure, crack growth with cohesive element)

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：  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!)

说明：  ABAQUS Python二次开发攻略-配书资源code(ABAQUS Python secondary development strategy - book resource code)

微电网 的仿真模型，包含了光伏，蓄电池等模块，能很好地仿真出各个模块的特性(The simulation model of the microgrid contains modules such as photovoltaics and batteries, which can simulate the characteristics of each module well.)

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)

对于非线性模型的跟踪预估问题，摒弃额对非线性函数进行线性化的做法，采用无迹变换处理均值和方差的非线性传递问题。(For the tracking and prediction problem of the nonlinear model, the linearization of the non-linear function is abandoned, and the traceless transformation is used to deal with the non-linear transfer of mean and variance.)

说明：  这是一个机器人轨迹跟踪控制的程序，应用的控制算法为滑模控制。(This is a robot trajectory tracking control program, the application of the control algorithm for sliding mode control.)
