说明：  实验二 作业调度实验本实验模拟单处理器系统的作业调度，加深对作业调度算法的理解。用某种语言编写和调试试一个作业调度的算法程序，有一些简单的界面，能够运行，仿真操作系统中作业调度的原理和过程。
(Experiment II job scheduling experiment this experiment simulated a single-processor system job scheduling, to deepen understanding of the job scheduling algorithm. A job scheduling algorithm program written in a certain language and debugging test, there are some simple interface and the ability to run, job scheduling simulation operating system principles and processes.)
