一、本程序针对操作系统中进程撤销相关理论进行实验。要求实验者设计一个程序，该程序

可模拟撤销多个进程及其子孙进程。

二、本程序针对操作系统中进程创建相关理论进行实验。要求实验者输入实验指导书提供的代码并进行测试。代码简化了进程创建的多个步骤和内容。进程的树形结构采用广义表的方式进行存储。

-First, the procedure for revocation of the operating system in the process of theory to experiment. Experimenter asked to design a program that can simulate the revocation process, a number of process and its descendants. Second, the procedures for the operating system in the process of creating the relevant theory to experiment. Experimenter asked to provide written input to guide the experiment and test the code. Code created to simplify the process and content of a number of steps. The process of generalized tree structure to store tables.
