隔离型DC-DC变换器降压仿真模型.使用了全桥结构,并移相控制算法实现,适用于大功率及对电气隔离有要求的电压变换系统. [boost.zip] - boost升压电路 matlab调试成功输出曲(Altar Simulink physics modeling board posted post: isolated two-way full bridge DCDC Resonant Converter... My simulation has been possible, the transformer has some problems, PWM correct phase shift generator, I have)

vcf132.ocx,我千辛万苦才从国外网站下到的最新控件,大家不要错过-vcf132.ocx, I untold hardships from overseas sites where the latest controls, we should not miss

主要完成 sip服务端任务的开发和实现 ，基于282181协议

本程序利用MFC树形工具控件实现各种形式的转换，可直接运行。(This program makes use of MFC tree tool control the conversion of various forms, can be run directly.)

可以在液晶显示两个数计算结果，只能进行两个数的计算(The results can be calculated by two numbers in the liquid crystal display)

地址薄管理器.采用MFC DAO对象和接口编程技术实现了一个地址薄数据库的管理器.主要功能包括:1,浏览数据库的内容.2,添加,删除和更新数据库的记录.(address book manager. Using MFC DAO objects and interface programming technology to achieve a one address book database manager. main features include : a browse the contents of the database .2, add, delete and update database records.)

Newton backward program using C

c#使用SOCKET进行文件传输 可大文件传输 断点续传

说明：  Bezier曲线的绘制，多项式系数的值由函数GetCnk计算，沿曲线路径的坐标位置由函数GetPointPr计算，最后由BezierCurve函数通过OpenGL画点功能实现曲线绘制。这里绘制的是一个包含4个控制点的三次Bezier曲线。(In Bezier curve drawing, the value of polynomial coefficients is calculated by function GetCnk, the coordinate position along the curve path is calculated by function GetPointPr, and finally the curve is drawn by Bezier Curve function through OpenGL point drawing function. Here we draw a cubic Bezier curve with four control points.)

说明：  AutoCA D D W G 图形文件结构，针对其复杂的数据格式提供了一种基于O penD W G T oolkit 直接访问D W G 图形文件的方法， 并给出了部分 C + + 实现代码(According to the structure of AutoCA's DWG graphics file, a kind of opendwg toolkit based on its complex data format is provided The method of accessing DWG graphic file directly, and some C + + implementation codes are given)
