这是一种基于线性加速度假设的用于编制大型程序的算法，即威尔逊法，可用于微分方程描述的问题计算仿真(This is an assumption based on the linear acceleration of procedures for the preparation of large-scale algorithm, namely, Wilson law, can be used in differential equations to describe the problem of simulation)

说明：  时频分析方法是非平稳信号处理的一个重要分支，它是利用时间和频率的联合函数来表示非平稳信号，并对其进行分析和处理，利用时频分析法对语音信号进行去噪。(Non-stationary time-frequency analysis is an important branch of signal processing, it is the joint use of time and frequency functions to represent the non-stationary signal and its analysis and processing, using time-frequency analysis of the speech signal denoising. )

利用二维有限差分法对单脊波导TM模进行计算。通过调整网格数目观察计算结果的精度，可以设定出最优的网格数目，然后改变波导中脊的尺寸，观察最低两个TM模对应的截止频率的变化规律，最后给出对应的横截面电场、磁场分布图(The two-dimensional finite difference method to calculate the single-ridge waveguide TM mode. The optimal number of grid can be set by the accuracy of the adjustment of the calculation result of the grid number observed, and then change the size of the waveguide ridge observed the lowest two corresponding to the TM mode of the cutoff frequency of the variation, and finally to give the corresponding cross cross-section of the electric field, magnetic field maps)
