大学三年级操作系统实验2作业调度，自己写的，当然也借鉴别人的-University three-year experiment 2, the operating system job scheduling, wrote it myself, of course, learn from others

恒流驱动和提 高LED的光学效率是LED 应用设计的两个关键问题，本文首先介绍大功率LED的应用及其恒流驱动方案的选择指南，然后以美国国家半导体(NS)的产品为例，重点讨论如何巧妙应用 LED恒流驱动电路的采样电阻提高大功率LED的效率，并给出大功率LED驱动器设计与散热设计的注意事项。-LED constant current drive and to improve the optical efficiency of LED application design of two key issues, this paper describes the application of high-power LED constant current driver and the choice of the program guide, and then the United States National Semiconductor (NS) products, for example, focus on how skillful application of LED constant current driver circuit of the sampling resistor to improve the efficiency of high-power LED, and gives high-power LED driver design and thermal design considerations.

这个是好东西，喜欢的就下，我都舍不得拿出来的自己去看吧，不介绍了-this is something good, like it, I want to come up with their own look at it, not introduced

超简单的下载系统，与夜猫下载系统相似，去掉分类功能，增加了广告功能，在后台可以自由添加删除广告，后台管理帐号和密码采用了md5加密码，确保密码安全后台登录地址login.asp 帐号和密码均为ah-md5login.asp ah

介绍了一种求解复杂优化问题的启发式算法--蚁群算法.该方法通过模拟蚁群对"信息素"的控制和利用进行搜索食物的过程-a distributed algorithm for the solution of combinatorial optimization problems which was inspired by the observation of real colonies of ants. We apply ACS to both symmetric and asymmetric traveling salesman problems. Results show that ACS is able to find good solutions to these problems
