说明：  只做了时间显示，和温度显示，使用一个按键切换(Only time display, and temperature display, using a button to switch)

运行于hadoop上的 MapReduce WordCount程序(Running on a MapReduce WordCount program hadoop)

基于单片机STC89C51和74LS164的多功能数字万用表(Based on microcontroller STC89C51 and 74 ls164 multi-function digital multimeter)

MSP430单片机常用模块连接原理的与操作实例(MSP430 microcontroller used to connect the module with the operating principles of instances)

msp430 g2553 和四线制的lcd1602连接，非常适合g2系列的io少的芯片使用(the msp430 g2553 and the four-wire lcd1602 connection is ideal for G2 Series fewer chips use io)

无线信道时延扩展仿真 一、仿真目的 　　　在数字通信中，无线信道所表现出的时延扩展将有可能引起接收信号的码间串扰。实验的目的是从时域角度方面对移动信道的多径环境引起的接收信号时延扩展现象进行仿真。(wireless channel delay spread simulation One, the simulation purpose In digital communication, wireless channel delay spread shown will likely cause the received signal crosstalk code. The aim of the experiment is to delay the received signal due to multipath environment of mobile channel in time domain and the phenomenon of simulation.)

说明：  使用51单片机控制某芯片，实现AD数模转换的功能。(A chip is controlled by 51 single chip computer to realize the function of AD digital-to-analog conversion.)

STM32运用PID控制DA输出电压稳定，可以设置。(STM32 using PID control DA output voltage stability, can be set.)

基于单片SST89V58RD2的I2C程序开发。用C语言描述的(I2C-based monolithic SST89V58RD2 program development. Described using C language)

1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)
