应用fluent进行两相流的仿真

合成孔径雷达（SAR)目标成像仿真，多姿态，多角度，有不同光照,小波包分析提取振动信号中的特征频率。( Synthetic Aperture Radar (SAR) imaging simulation target, Much posture, multi-angle, have different light, Wavelet packet analysis to extract vibration signal characteristic frequency.)

用于拓展fluent磨损模型的UDF，采用tabakoff经验公式描述磨损量。(a udf to optimize erosion model in Fluent)

通过滑动T检验时间序列的变化趋势，一般多用于气象分析(T-test time series by sliding the trend, generally used for weather analysis)

说明：  利用时域有限差分计算电磁场，采用时域算法计算(Calculation of electromagnetic field by FDTD)

替代数据方法（基于相位随机化方法），检验续写的非线性(Surrogate data method (based on random-phase method), non-linear write test)

此源码包是我本学期最优化理论课程的大作业，其中包括了我自己写的以下常用最优化算法的实现代码：最速下降法，牛顿法，非线性最小二乘法，DFP法。fun1，fun2是两个测试函数。谢谢！(This is my source packages optimization theory this semester courses in large operations, including my own to write the following commonly used optimization algorithm code: steepest descent method, Newton method, nonlinear least squares method, DFP method. fun1, fun2 are two test function. Thanks!)

同伦算法解非线性方程组，构造不动点问题,并从不同的初始点出发运行程序。(To solve nonlinear equations with homotopy algorithm，constructing a fixed foint progrem.and from the different starting point to run the program. )

先通过emd进行分解，然后求出边际谱，进行分析(First, the EMD is decomposed, and then the marginal spectrum is obtained)

一种借助lowtran7计算大气透过率和目标辐射的软件平台ART2100(A program that used for calculate air transferrate and object randience based on lowtran7)

计算多材料单元平均应力应变,用于提取计算等效弹性模量 泊松系数(Calculate the average stress-strain of multi-material elements)
