算十万的阶乘,对于计算机和程序员都是一个挑战,本源程序实现了求大数的阶乘,是用汇编写的,相对速度很快,算十万的阶乘在我赛扬2.4,内存256的神舟笔记本上,用了20多分钟.算出得数写在一个TXT文件下,十万的阶乘结果,用记事本打开,都要好一会儿.-Count of thousands of factorial, for computers and programmers is a challenge to realize the source of the order of the factorial of large numbers, is written in the compilation of a relatively quick, and counting of thousands of factorial in my 2.4 Celeron, memory 256 Shenzhou notebook, spent more than 20 minutes.得数calculated to write in a TXT file, the thousands of factorial results, use Notepad to open, should a good moment.

基于单片机控制的电子密码锁 摘要：本系统由单片机系统、矩阵键盘、LED显示和报警系统组成。系统能完成开锁、超时报警、超次锁定、管理员解密、修改用户密码基本的密码锁的功能。除上述基本的密码锁功能外，还具有调电存储、声光提示等功能，依据实际的情况还可以添加遥控功 -Based on MCU-controlled electronic code locks Abstract: This system consists of single-chip microcomputer system, matrix keyboard, LED display and alarm system. System to complete the unlock, overtime alarm, lock超次, administrators decrypt, modify the user s password locks the basic functions. In addition to the above basic code lock function, but also has a transfer electric storage, sound and light features such as tips, according to the actual situation can also add a remote control reactive
