设计数字基带传输系统，利用MATLAB强大的仿真功能，结合其所具有的图形叠加特性，针对余弦滚降最佳接收系统、部分响应系统进行仿真，通过观察仿真眼图、频谱图、功率谱图以及误码率曲线，检测系统的码间串扰和传输质量。(This article designs the digital baseband transmission system, uses the MATLAB formidable simulation function,unifies graphsuperimposition characteristic which it has,we has simulatived optimal reception of characteristic of roll-off and the partial response system,through the observation to simulation of eye pattern,frequency spectrum,power spectrum,bit error rate,detected intersymbol crosstalk and the transmission quality to system.)

说明：  本书以MATLAB为基础，介绍了MATLAB电气系统模型库模块及其功能，并以实例介绍了电力电子和电机控制系统的建模和仿真方法。(MATLAB-based book introduces MATLAB electrical system model library modules and functions, and describes examples of power electronics and motor control systems modeling and simulation methods.)

分别使用penalty,Brige-Massart和缺省阈值对信号降噪(Respectively using penalty, Brige-Massart and default noise reduction threshold to denoise)

电力谐波带来了严重的危害，有源滤波器是抑制电力谐波的一种有效手段。在Matlab 仿真环境中搭建了有 源滤波器的系统模型，并对其进行了仿真。仿真结果表明，各仿真模块能够完成各自的功能，整个系统的滤波效果非 常好。因而，该仿真模型能对软、硬件的设计起到重要的指导作用(Power Harmonics brought serious harm, active filter is an effective means of suppressing power harmonics. In the Matlab simulation environment to build a model of the active filter system and its simulation. The simulation results showed that the simulation module to complete their respective functions, the filtering effect of the whole system is very good. Thus, the simulation model capable of hardware and software design plays an important role in guiding)

Arduino hx711库文件，在编写程序省去很大力气，很好用的头文件，大力推荐(Arduino hx711 library files, eliminating the need to write programs in a lot of effort, a good use of header files, strongly recommended)

黑油模型数值模拟入门指南 市场上有不少关于油藏数值模拟的书，但好像没有类似围棋入门指南那样从基础开始一步 一步介绍的书。我收到不下二十个问油藏数值模拟如何入门的问题。我尝试写一写油藏数值模拟 入门指南，希望对那些刚刚开始进入油藏数值模拟领域的工作者有所帮助(Numerical simulation of black oil model Start Guide on the market, many of reservoir simulation, but it seems there is no similar entry guidelines go as the beginning of step by step from basic introductory book. I have received no less than 20 reservoir simulation asked how the issue of entry. I try to write to write a reservoir simulation Start Guide, I hope for those just beginning to enter the field of reservoir simulation will help workers)
