Slow, continuous change may be the norm during periods of environmental stability, while rapid evolution of new species occurs during periods of environment stress.
缓慢的、持续的变化可能是环境稳定时期的常态，而新物种的快速进化发生在环境压力时期。

And yet no documented and proven, system-wide stress test exists currently that can test the stability of the Linux kernel in its entirety.
然而还没有被证明和证实当前现有的系统范围内的压力测试可以测试Linux内核整体上的稳定性。

The final result is a stress test that covers enough of the Linux kernel to be useful for stability statements, and that has the system usage and kernel code coverage data to support it.
最终得到的压力测试涵盖了 Linux 内核的足够多部分，有助于稳定性声明，并且有系统使用情况和内核代码覆盖情况的数据来支持它。
