改程序适应于电力系统短路电流计算，生成节点导纳矩阵和阻抗矩阵。(Change program suitable for power system short-circuit current calculation, to generate the node admittance matrix and the impedance matrix.)

说明：  这是一个使用了8位移位寄存器HC595的电子钟程序，里面包括了仿真程序。以及HC595的操作说明。(This is a used 8-bit shift register of the electronic bell HC595 procedures, which include the simulation program. As well as instructions HC595.)

说明：  系统工作电源AC220V 根据室内光线调节遥控灵敏度。 主控室电脑负责接收由控制终端传来的遥控信号播放相应多媒体影音文件； 通过主控电脑也可直接点播各展品文件，同时控制打开对应的展品照明； 遥控终端接收激光棒控制信号，控制开灯照明正在解说的展品，并通过通信总线通知主机播放相应文件； 通信中继器负责全部终端与主机间的双向信号传递； 扩展功能：设计上位机播放操作软件，控制照明灯亮度。 (无)

说明：  本压缩包中详细介绍了电动机的单片机控制的有关方法(The compression package described in detail the single-chip motor control of the method)

在STM32F4平台上移植的ucos-ii和ucgui,很适合正在学习ucos-ii和ucgui的朋友(On STM32F4 porting ucos-ii and ucgui, very suitable for studying ucos-ii and ucgui friend)

this .rar contain source code in basic for avr microcontroller for making drifter device to measure water velocity on the sea surface

根据IAPWS-IF97和IFC67编写的水和蒸汽性质计算软件(the software for calculating the properties of water and water vapor)

使用DataAdapter对数据库进行操作 将SQL-search.aspx程序可改为使用DataAdapter对数据库进行操作. 程序使用"Dim objAdapt As New OleDbDataAdapter(strcmd,objCon)"创建了DataAdapter对象。(Use DataAdapter to operate the database The SQL-search.aspx program can be changed using the DataAdapter to operate the database. The program uses "Dim objAdapt As New OleDbDataAdapter (strcmd, objCon)" Creating a DataAdapter object. )

毕业设计时做DC600V逆变器测试系统，采用工控机为主控制器，PCL-818数据采集卡， VC++作编程工具，对25T、25k型客车使用的逆变器进行性能测试。(Graduation time to do DC600V inverter test system, IPC-based controller, PCL-818 data acquisition card, VC++ as a programming tool, 25T, 25k bus-type inverter used for performance testing.)
