说明：  NETEM 的预测试题(NETEM questions)

matlab编程必备，很实用的电子教程，是学习MATLAB的首选(MATLAB)

包络分析大多在原始振动加速度信号基础上进行， 受噪声干扰等因素的影响较大 通过对原始振动信号自相关函数作包络分析， 可以有效地抑制噪声， 突出反映故障调制特征(s． Most of the envelope analyses are based on original vibration accelera- tion signal，which is seriously influenced by noise interference． The noise is effectively suppressed by envelop analysis of auto correlation function of original vibration signal，and the modulation characteristics of fault are highlighted．)

说明：  简单实现了基于项目的协同过滤代码，MATLAB实现，需要解压(Simple implementation of project-based collaborative filtering code)

Joannopoulos "Photonic crystals. Molding the flow of light" - one of the best books on photonic crystals(Joannopoulos "Photonic crystals. Molding the flow of light"- one of the best books on photonic crystals)

利用matlab语言，对STL格式的数据实现图形的仿真(Use of matlab language, STL format data to achieve graphics simulation)

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标距离信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
