这是大地电磁一维正演程序，只要输入电阻率和深度即可正演计算；使用的是卡尼亚视电阻率公式，有关说明已经在文件中说明。(This is a one-dimensional magnetotelluric forward the program, as long as the input resistivity and depth to forward calculation use Carney ATV resistivity formula, and instructions in the file description.)

说明：  同伦连续算法，很好得用来求解非线性方程组(Homotopy continuation method, may very well be used to solve nonlinear equations)

CFD数值模拟，经典PISO算法程序源程序代码。(CFD numerical simulation, classic PISO algorithm source code.)

说明：  采用电磁仿真软件HFSS进行雷达散射截面(RCS)计算实例.(Monostatic Radar Cross Section)

fluent模拟焊接，熔滴过渡的质量源项(Welding Simulation， mass source)

有限元计算控制加载中弧长法（arc-length）的matlab源程序(Loading FEM arc length control method (arc-length) matlab source)

用刷选法求出100之内的素数。并输出数有多少个。(100 prime number is calculated by the method of selection. And the output count how many.)

对于PID算法给予了通俗易懂的讲解，有利于初学者快速掌握PID的要领(I give the PID algorithm the understandable explanation，which will help beginners to quickly master the PID essentials)

smote过采样方法对不平衡数据集进行人工数据合成(smote oversampling and classification)

在有限元分析中的网格划分好坏直接关系到模型计算的准确性，这里是关于网格划分的一些讨论。(In in the analysis of finite element mesh is directly related to the accuracy of the calculation model, there is some discussion about grid division.)
