Setting this variable to on provides a more proactive approach to page cleaning than the default approach (based on CHNGPGS_THRESH and LSN gap triggers).

通过将这个变量设置成on，可以为页清除提供一种比缺省方法(基于CHNGPGS_THRESH和LSN间隙触发器)更积极的方法。

Suppose a signal is generated during the very small time gap between setting the errno variable by the close system call and its return.

假定信号在close系统调用设置errno变量到其返回之前这一极小的时间片段内生成。

The simulated thickness with separation force is smaller than that with blank-holder gap because the BHF is variable in the flange region.

采用分离力时的模拟厚度比压边间隙小是由于法兰区域的变压边力。
