摘　　要：分析在单处理器操作系统中发生死锁的原因和解决方法。采用银行家算法和死锁检测算法来实现多个进程之间的并发执行。在对经典的银行家算法进行模拟的过程中,认识到它在现实应用中还存在的问题,提出可以改进的方法,并对改进前和改进后的时间效率进行了比较。It was analyzed the cause of deadlock and its solution in Single-processor Operate System, adopted the Banker＇s Algorithm and the deadlock check Algorithm to achieve the concurrence of many process. During the process of simulating the classical Banker＇s Algorithm, it was found there were a lot of problems when it was applied to the practical system, put forward the improved method, compared the time efficiency.
