一、　　进程控制

目的：利用简单的结构和控制方法模拟进程结构、进程状态转换和进程控制。

方法：用PCB表示整个进程实体，利用键盘交互式命令控制方法模拟进程执行中产生的事件。

-First, the process control purposes: the use of a simple structure and control method for simulation of the process structure, process state transitions and process control. Methods: The PCB said that the whole process entities, the use of keyboard commands to control an interactive simulation of the process of implementation arising from the incident.
