飞机强度计算中的有限元与CAD_CAM一体化的讲解说明的课件，很有用的，大家下载看看吧(Aircraft strength calculation of the integration of finite element and CAD_CAM explained that the courseware, very useful, we look at it download)

电力系统两机振荡仿真分析，500kV交流线路(Two machine oscillation in power system in PSCAD.)

系统辨识作业 考虑如下模型 z(k)-1.5z(k-1)+0.7z(k-2)=u(k-1)+0.5u(k-2)+v(k) 其中v(k)是均值为0，方差为1的白噪声。根据模型生成数据，采用递推最小二乘法对模型参数进行辨识，要求绘出各参数随时间的变化曲线。 ("System identification" computer test 。Consider the following model Z (k) to 1.5 of z (k- 1)+ 0.7 z (k- 2) = u (k- 1)+ 0.5 u (k- 2)+ v (k) The v (k) is the mean to 0, the white noise variance 1. Generate data according to the model, the recursive least squares method is adopted to model parameters are identified, draw the parameters changing with time curve. )

计算两条曲线的相似度，作为判断两条曲线相似度的依据(to calculate the frechet distance of two curves)

PSCAD程序，自主搭建了同步发电机和简易的电力系统，用于实现电压和无功控制(PSCAD program, independent and easy to build a synchronous generator power system for implementing the voltage and reactive power control)
