说明：  中断系统是整个计算机系统必不可少的重要组成部分。利用中断屏蔽技术修改中断优先级(Modifying interrupt priority with interrupt mask technology)

最简单的操作系统，使用nasm来编译,启动会显示一些字符串smile米奇333(The easiest operating system to use nasm to compile, will start to show some strings smile Mickey 333)

1）设计一程序，由一个进程创建三个子进程，三个子进程一个是生产者进程，两个是消费者进程。 2）父子进程都使用父进程创建的共享存储区进行通信，由生产者进程将一个数组中的十个数值发送到由5个缓冲区组成的共享内存中。? 3）两个消费者进程轮流接收并输出这十个数值，同时将两个消费者进程读出的数值进行累加求各和。 4）考虑生产者进程生产的速度和消费者进程速度。(1) a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process. 2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L 3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes. 4) take into account the production speed of the producer process and the speed of the consumer process.)

说明：  idl的二次开发，用idl代码直接计算植被覆盖度(Using IDL code to calculate vegetation coverage directly)

一份用通俗易懂的语言简述操作系统的文档，内容非常适合初学者(A brief plain language operating system s documentation, the content is very suitable for beginners)

银行家算法模拟程序的实现 用可视（图形）化界面完成银行家算法的模拟程序。 模拟程序能够实现对不同数目进程，不同数目资源种类，不同当前状态的测试，通过银行家算法判断任意次数的资源请求是否会得意满足，并对提出资源请求的进程作出正确处理。 模拟程序还需要能够正确回收资源，并在回收资源后判断是否需要唤醒阻塞进程，如需要则将先前因申请资源失败而被阻塞的进程唤醒，并提供资源分配(Bankers algorithm simulation program realization )

利用labview开发的信号采集系统，能够很好的进行仿真信号采集！(Use of LabVIEW development of signal acquisition system, able to simulate a very good signal acquisition!)
