scale disk

QPO is believed to be an effective approach to detect the accretion process near BHs since its time scale is equivalent to the dynamical time scale in the inner region of an accretion disk.

由于其时标与黑洞吸积盘内区的动力学时标相当，QPO被认为是探测黑洞附近吸积过程的有效途径。

In a large scale real time simulation system, methods to reduce disk I/ O time at the ACP QIO I/ O interface as well as to improve the real time performance in a multiple processes environment, are introduced in this paper.

本文以一个大型实时仿真系统为背景，介绍了在ACP－QIO这一I／O层次减少磁盘I／O操作时间的诸多方法，以及在多进程环境下提高进程实时的一些措施。
