根据经纬度计算子午线收敛角，便于进行收敛角改正

孙鑫老师的VC++教程的光盘源代码，数写的很好，代码也很好，值得研究！第19章源程序！-SUN Xin teachers VC++ Tutorial CD-ROM source code, written in a few very good, code is also good, worthy of study! Chapter 19 source code!

工控机需要能够可靠稳定的运行，但是由于复杂的环境及工况，工控机也会因为意外死机。利用单片机组成的硬件结构，通过监测工控机的串口，监测工控机是否在正常工作，当工控机因为意外死机后，通过将工控机的复位线接入单片机复位电路，利用硬件结构实现工控机的复位。

一个模仿Windows7桌面平台的源代码~写得好的画可以替代windows的桌面。集成了背景切换，右键换背景 目前只能换1次 （偷懒了点没写循环更换）。双击关闭。支持图标透明，其中里面有个真正的透明通道控件――存在于Arone中。Arone中每个Item都是一个单独的控件。背景是在Form中，控件跟背景是透明融合。作者vIstaswx本来打算再写写去参赛的，结果先放给了本站，呵呵，再次感谢这个对GDI+技术高超的孩子。-An imitation of the source code for desktop platform Windows7 ~ write a good painting can replace the windows desktop. Integration of the background to switch, right-for the background is currently only available for a time (a point I did not write cycles lazy replacement). Double-click Close. Support icons transparent, inside of which there is a genuine and transparent access control- exist in Arone in. Arone Each Item is a separate control. Background is in the Form, the control integration with the background is transparent. By vIstaswx originally intend to write to the competition, the results of the first release to the site, Oh, once again thank the pairs of GDI+ highly skilled children.

电力工作者常用软件，通过录入线路参数，形成导纳矩阵，用于电力潮流、仿真等基本计算-electric power admittance building program,accordind liner parameter become a linear matrix,it use for elecrtronic circuit ...etc

[[[基本计算器]]]

自己使用vb编的一个计算各种滤波器参数的程序-its own use vb series of the calculation of a variety of filter parameters of the process

一本讲解关于C的基本函数属性的比较好的电子书，希望大家看了会觉得有用。，另外感谢上传者，辛苦了-One explain the basic functions on the properties of C, better e-books, hope that readers will find useful. In addition thanks From, it is tough
