操作系统实验中的进程创建与删除

1)　　采用动态或静态方法生成一颗进程树（进程数目≥20）；

2)　　设计进程撤销算法；

3)　　实现进程撤销函数，采用级联方式撤销；

4)　　可动态撤销进程；

5)　　可动态观察进程树的情况；

6)　　测试程序并得到正确结果。

-Experiment operating system process creation and deletion of 1) the use of dynamic or static method to generate a process tree (the process of the number of ≥ 20)　2) the design of the process of revocation algorithm　3) the realization of the process of withdrawal function, the use of cascading revocation way　4) dynamically revocation process　5) to observe the process of dynamically tree situation　6) test procedure and the correct result.
