The expression uses the *VALUE, *LT, *AND, and *EQ criteria functions to test for the condition CPU idle time being too low.

表达式使用 *VALUE、*LT、*AND 和 *EQ 标准函数来测试 CPU 空闲时间过低的条件。

Programs which make use of CPU Idle Time mean that they run at a low priority so as not to impact programs that run at normal priority.

当程序利用CPU空闲时间的时候，就意味着它们以较低的优先权运行着，以便不会影响那些有正常优先权的程序运行。

Many programs that use CPU idle time cause the CPU to always be 100% utilized, so that the time spent where the CPU would have been idle is instead spent performing useful computations.

许多使用CPU空闲时间的程序造成CPU总是100%地被利用，这使得本是CPU进入空闲状态的时间被花在执行有用的计算上面。
