说明：  进行PQ分解，计算电力系统潮流的有效方法，应用广泛(PQ decomposition is an effective method for calculating power flow in power system.)

螺旋桨唱音信号建模，FFT变换后有明显的谐波(The propeller singing sound signal is modeled, and FFT transformation has obvious harmonic )

1） 应用C语言编写程序，计算弹道，并绘制结果曲线。 给出系统脱靶量统计结果（用蒙特卡洛法）。 (torpedo)

四阶龙格库塔法，用C++编写，很有参考价值(Fourth-order Runge-Kutta method, written in C, a good reference)

svd分解，使用qr方法，编译即可运行，需要文件输入(SVD QR method，the program can run successfully, you need a file for input)

基于Python编写的用于曲线拟合，最小二乘法(Based on Python for curve fitting, least squares method.)

灰色预测模型，对未来数据进行预测，同时还有误差检测(GM(1,1),Grey prediction model, which can forecast future data and detect errors at the same time)

ransac直线拟合：使用ransac方法剔除不好的点，留下好的点做直线拟合，这样拟合出的直线更符合实际，因为没有了错误数据的参与。(ransac linear fitting: Use ransac methods eliminate the bad points, making a good point to make fitting a straight line, so that the fitted straight line is more realistic, because there is no involvement of erroneous data.)

说明：  基于结构网格二维Euler方程的Jameson求解方法 自己写的程序，网格是现成的结构网格(Jameson solution method based on two-dimensional Euler equation of structural grid. Write their own procedures, the grid is ready - made structural grid.)

采用QR分解方法计算矩阵特征值和特征向量(computes a partial Schur decomposition of a square matrix or operator)
