说明：  计算时滞微分方程的李雅普诺夫指数，动力学维数(Delay differential equations Lyapunov index calculation, dynamic dimension)

利用BP分类器对烟雾图像进行识别，并将结果存储到TXT文档中。(BP classifier use smoke image recognition, and stores the result TXT document.)

基于newmark法的多自由度系统瞬态分析( Transient Analysis of Multi-degree system based on Newmark method)

说明：  使用Matlab编写的逆谐波程序。该程序对于不同的参数进行了实验。当图像噪声不同时，选用不同的参数。参数的正确选择很重要。本程序给出了不同噪声比较适合的参数选择(The use of Matlab procedures for the preparation of the inverse harmonic. The program parameters for different experiments. When the image noise is not at the same time, choosing different parameters. Correct choice of parameters is very important. This procedure gives more suitable for different noise parameters)
