Mean quantum time should be close to 500 microseconds, and the maximum quantum times must be monitored to ensure they fall within the acceptable pause times for the RT application.

普通的时间量接近500微秒，而且必须对最大的时间量进行监控以保证它们能够为RT应用程序提供可接受的暂停时间。

And there are various forces that play in the nucleus that will dictate when this will be stable and when it won't be.They isolated it, but it decays very quickly on the order of microseconds Lifetime on the order of microseconds.

在原子核中有很多种力,都会产生作用，当条件是稳定的,还有当它不是的时候，它们提取出来，但是它会以微秒的速度衰变,生命只有几微秒长。
