摘要
本文阐述了虚拟存储中各类置换算法的基本思想、算法的实现，并比较了它们的优缺点，以及在同一置换算法中对该算法的几种不同分析理解方法。最后把置换算法进行了综合性性能分析，讨论了如何才能把缺页率保持在一个合理的水平上。
This article elaborates the basic thoughts of all kinds of substitution algorithm in virtual storage and the realization of algorithm, It also compares their advantages and disadvantages, puts forward several different analysis and comprehension methods, carries on comprehensive performance analyses of substitution algorithm and discusses how to keep the rate of page lack on a reasonable level.
