中文说明： 数据模型归一化，模态振动，比较了软阈值，硬阈值及当今各种阈值计算方法,电力系统暂态稳定程序，可以进行暂态稳定计算,非常适合计算机视觉方面的研究使用,窗函数法设计一个数字带通FIR滤波器，仿真效果非常好。
English Description：
Data normalization model, modal vibration, soft threshold, hard threshold and the current threshold calculation method, power system transient stability program can for transient stability calculation, very suitable for computer vision research use and window function method to design a digital band pass FIR filter, simulation results very well.
