多任务OS中多线程同步问题的实验模拟

The Experiment Imitate for Multi-thread Synchronism Question

在学习OS（操作系统）理论的过程中，学生对线程及多线程同步理论的理解，一般较难有感性的认识。针对这一问题设计了相关实验，并以所学理论知识作为依据，结合具体OS的使用，对所提出的问题进行合理地解决。

During studying the theory of OS(Operate System), there are some hardships to understand the thread and multi-thread synchronism theory. I do some works to study these questions, and design some experiments. In these experiments, questioned point to above mentioned-question, and combine with the use of the particular OS, answered and solved it.
