说明：  该文档为ANSYS仿真开发实例，为某扁挤压筒的热结构耦合分析，格式为txt，请自行如有需要请自行修改并复制到ANSYS开发界面运行。(This document is an example of ANSYS simulation development. It is a thermal structure coupling analysis of a flat extrusion tube. The format is TXT. Please modify and copy it to the ANSYS development interface if necessary.)

粗糙表面压力摩擦力及摩擦系数之间的关系，高斯分布(Relationship between pressure and friction coefficient of rough surface and Gauss distribution)

地震数据f-k滤波效果分析，地震数据处理(Seismic data F-K filtering)

能根据时间、潮位数据，自动计算高潮位、低潮位及相应的时间和潮差值，出图并将计算结果保存在excel文件。(According to the data of time and tide level, the high tide level, low tide level, corresponding time and tide difference can be calculated automatically, and the result can be saved in Excel file.)

采用相场方法，计算合金中枝晶生长，标记为相场模型C_alloy。(Dendrite growth in the alloy was calculated by phase field method and marked as phase field model C_alloy.)

表示相空间相邻轨迹的平均指数发散率的数值特征。又称李雅普诺夫特征指数，是用于识别混沌运动若干数值的特征之一。(Denotes the numerical characteristics of the average exponential divergence of adjacent trajectories. Also known as the lyapunov characteristic index, is one of the characteristics used to identify some numerical values of chaotic motion.)

说明：  海水温盐深剖面测量设备的串口实时数据采集实现Deep-sea water temperature and salinity profiling serial devices to achieve real-time data acquisition(Deep-sea water temperature and salinity profiling serial devices to achieve real-time data acquisition)

选取四个点，自动判断是否在一个平面上。同一个平面上。则绘制一个多边形。不在一个平面，则以前三个点为底面，构成一个椎体。支持Move等转换命令，存图与开图，实现Jig交互绘制等。(Four points are selected to automatically determine whether or not they are on a plane. On the same plane. Draw a polygon. If it is not in a plane, the first three points are at the bottom, forming a vertebral body. Support Move and other conversion commands, save and open maps, Jig interactive rendering, etc.)

用于计算多普勒频移的函数，MATLAB语言，挺好用。(The function for calculating Doppler frequency shift, MATLAB language, is very useful.)

说明：  根据舰船螺旋桨噪声一书给出的计算空泡噪声的公式，简便计算各种条件下的螺旋桨噪声级的程序(According to the formula for calculating the cavitation noise given in the book "Propeller Noise of Ships", the program for calculating the propeller noise level under various conditions is simple and convenient.)
