说明：  便携式表面粗糙度仪设计与实现Portable surface roughness instrument design and implementation(Portable surface roughness instrument design and implementation)

设计了一基于现场可编程门阵列（FPGA）的低频数字式相位测量仪。该测量仪包括数字式移相信号发生器和相位测量仪两部分，分别完成移相信号的发生及其频率、相位差的预置及数字显示、发生信号的移相以及移相后信号相位差和频率的测量与显示几个功能。其中数字式移相信号发生器可以产生预置频率的正弦信号，也可产生预置相位差的两路同频正弦信号，并能显示预置频率或相位差值；相位测量仪能测量移相信号的频率、相位差的测量和显示。两个部分均采用基于FPGA的数字技术实现，使得该系统具有抗干扰能力强, 可靠性好等优点。()

两线制压力变送器设计两线制变送器的原理是利用了4~20mA信号为自身提供电能。本文档详细介绍了两线制压力变送器的特点以及参考电路图(2-wire pressure transmitter 2-wire transmitter design principle is the use of the 4 ~ 20mA signal to provide power for itself. This document details the two-wire pressure transmitter features and reference schematics)

基于SIMULINK对开关磁阻电机做的仿真工作，内容非常详细。(SIMULINK simulation of switched reluctance motor do the work, the content is very detailed.)
