防雷工程是一项系统工程，要求将外部防雷装置和内部防雷装置统一考虑，着眼于全方位的雷电综合防护，把机房建筑物的防雷、雷电电磁脉冲（LEMP）防护、设备防雷、电源系统防雷、线路防雷、接地系统、保护装置等综合因素考虑在内。任何方面的遗漏带来的危害都是不能(Mine is a systems engineering project, requiring the external and internal lightning protection lightning protection devices to consider a unified, integrated focus on the full range of lightning protection, lightning protection of buildings to the engine room, lightning electromagnetic pulse (LEMP) protection, equipment, anti- Thunder, lightning protection power system, line lightning protection, grounding systems, protective devices and other comprehensive factors into account. Omission of any harm is not)

决策树的Matlab实现，实现了分类问题和回归问题，有很好的调试结果(Matlab implementation of decision trees)

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.)

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k. A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed.

在matlab中实现关于logistic映射的混沌序列的仿真(the realise of chaos sequence in matlab)

基于matlab simulink 的六连杆模型，可以对速度，加速度，位移进行仿真，不用推倒数学公式，仿真容易实现(Based on the six linkage matlab simulink model, for speed, acceleration, displacement simulation, do not tear down the mathematical formulas, easy to implement simulation)

功率谱密度估计。welch法功率谱密度估计，协方差法估计，Burg法估计。(psd estimate。welch，covariance，Burg。)
