数字滤波的例子，巴特沃斯与切比雪夫的横向和纵向对比，及阶数分析(Digital filter example, Butterworth and Chebyshev comparison of horizontal and vertical, and the order of)

二维波导中计算反射系数，两边为PML，上下为PEC，波源为平面波(two-dimensional waveguide reflection coefficient calculated on both sides of the PML and bottom of the PEC, for the plane wave Boyuan)

超宽带基础的基本程序,非常不错的小程序,省不少事情啊(the basic procedures, a very good small procedures, many of the things the provincial ah)

报道了在掺钛蓝宝石环形激光器中加入非线性折射率 n2较大的 SF-57玻璃形成腔内可控 的 SPM效应 ,并引入适当的负 GVD,将脉冲宽度从 30 fs压缩至 16 fs,相应的脉冲压缩率为 47 (Join the nonlinear refractive index n2 reported greater SF-57 titanium sapphire glass ring laser cavity formed in a controlled The SPM effect, and the introduction of a suitable and negative GVD, the pulse width 30 fs compressed to 16 fs, corresponding pulse compression rate of 47 )

语音端点检测，是语音压缩时提取特征参数的一个必要的过程，这个程序主要是对这个过程的一个小的程序。希望对学语音的有帮助(Extreme point detecting is a primily process to get the eigenparameter when you compressing the speech.This program is a small one,it will help for the learner.)
