If the page is unmodified, the page replacement daemon can simply mark the physical memory block as free, and the physical memory block can then be re-used for another page.
如果该分页没有经过修改，那么分页替换守护进程可以简单地将物理内存块标记为空闲，这样一来，就可以将该物理内存块重用于另一个分页。
As physical memory on today's workstations get larger and larger, the table used for memory translation must consume more and more resources to map the working memory set.
随着当今工作站上的物理内存越来越大，用于内存转换的表必须消费越来越多的资源，以映射工作内存集。
