Memory locking is a way to ensure that a process stays in main memory and is exempt from paging.

内存锁定是一种保证某进程驻留在内存而不需换页的方法。

To resolve the problem of color transformation in simulation process,this paper improves the speed of arithmetic by the way of query all level intensity of RGB color quantity stored in advance and in the terms of DirectDraw page flipping.

针对仿真过程中色彩转换相对困难的问题,采用查询预先存储的RGB颜色分量的各级强度值的方式,结合DirectDraw的换页技术,加快了算法的运行速度。
