说明：  三相并联BUCK电路，和单相buck相比功率更大。(The three-phase parallel BUCK circuit is more powerful than the single-phase BUCK circuit.)

2005年华为c的面试题，希望能够对拼命找工作的人有所帮助。(c 2005 for Love to face questions, hoping to find work desperately to the people some help.)

This program is the realization of Adaboost selection algorithm in C++. Examples have been included in the zip file updated.

这是数据库设计的一个结果，利用了pb软件，结合数据库可以运行-This is a result of database design, use of pb software, combined with the database can run

ESRI SHAPE文件读/写源代码。SHAPE是GIS中的重要文件格式，本代码对于研究SHAPE文件格式，实现独立代码读/写SHAPE而言，将非常轻松。建议首先阅读SHAPE文件格式白皮书。-ESRI SHAPE document read/write source code. SHAPE is a major GIS file format, the code for research SHAPE file format, achieve independent code reading/writing SHAPE, will be very relaxed. SHAPE proposal was first read the White Paper document format.

程序完全开源，无加密，无期限，无域名绑定。除了之前人能见的小错误修复之外：增加修复了最新齐博后台上传拿SHELL漏洞增加修复了最新齐博遍历目录任意删文件漏洞注意：对于多城市版并且使用的是IIS服务器，同时想使用多城市二级域名与商铺三级域名的话，请把/home/bak/目录下的3个PHP文件移到根目录，然后在IIS上添加一个空主机头绑定到根目录（IIS只能设置一个空主机头），同时还要添加hy.php为默认主页，并且优先级要高于index.php才可！(The program is completely open source, no encryption, no deadline, no domain name binding. In addition to the minor bug fixes that have been seen before: an increase in the repair of the latest flush backstage upload SHELL vulnerability to the latest Qi Bo traversal directory arbitrary deletion note: for the multi city version and the use of the IIS server, and want to use the multi city two domain name and the shop three domain name, please /home/ The 3 PHP files in the bak/ directory are moved to the root directory, then a null host header is added to the root directory on the IIS (IIS can only set an empty host head), and hy.php is added as the default home page, and the priority is higher than index.php!)
