平均路径长度&聚类系数计算

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.)

用于温度场film边界条件，算例算例算例(This text is used for temperature field in ABAQUS user-defined subroutine which is called film.)

三维比例导引法仿真，可以攻击静止/机动目标(Three dimensional proportional navigation simulation can attack stationary / maneuvering targets)

说明：  一个计算铜的热导率的in文件，基于lammps软件(An in file for calculating thermal conductivity of copper)

说明：  车辆二自由度（三种方式），三自由度，四自由度车辆模型，参数齐全，可完美运行，绝不忽悠！(Vehicle two degrees of freedom (three ways), three degrees of freedom, four degrees of freedom vehicle model, complete parameters, perfect operation, never fooling!)

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：  采用Python脚本语言二次开发ABAQUS的前处理模块创建了一个带孔平板模型，实现了参数化建模。(Parametrical model using Python in Abaqus.)

说明：  卫星姿态是指卫星星体在轨道上运行所处的空间指向状态。将直角坐标系的原点置于星体上，指向地面的Z轴反映偏航方向，Y轴反映俯仰方向，X轴反映滚动方向。星体在高空中沿局部地球铅垂方向和轨道矢量方向运行，不时地产生对三轴的偏移。姿态控制是通过姿态控制分系统（ACS）来实现，使用地平扫描仪可感应俯仰和滚动轴的姿态误差，使用速度陀螺仪和罗盘可感应偏航轴的姿态误差。(Satellite attitude refers to the spatial orientation of a satellite in orbit. The origin of the Cartesian coordinate system is placed on the star, the Z axis pointing to the ground reflects the yaw direction, the Y axis reflects the pitching direction, and the X axis reflects the rolling direction. The stars move along the direction of the earth's vertical direction and the orbit vector in the high altitude, resulting in the deviation of the three axis from time to time. Attitude control is realized by attitude control subsystem (ACS). The attitude error of pitch and rolling axis can be induced by using horizon scanner, and the attitude error of yaw axis can be induced by using speed gyroscope and compass.)

使用zernike多项式进行光学像差的拟合，从而进行光学镜面像差的分析，有助于提高光学系统的加工精度。(The Zernike polynomial is used to fit the optical aberration, and the analysis of optical mirror aberration is helpful to improve the machining precision of the optical system.)

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