例如，如果你想增加一些代码来监视什么方法被调用，它的参数以及它内部的算法和计算是怎样工作的，那么你就可以自己定制一个探针。

For example, if you wanted to add some code that monitored what method was being called, its parameters, and how an internal computation or algorithm is working, then you can define a custom probe.

有一些类型的工作项包含了与时间计算相关的信息，而有的则不含，所以我们必须使用不同的算法，来估计不同类型工作项的工作项状态。

Some types of work items contain information relative to the time scales, and others do not, so we have to use different algorithms to calculate the work item status of different types of work items.

有大量这类算法和它们的变体，人们一般会以为随便哪一位计算机科学家都了解它们是如何工作的。

These algorithms and their variants show up a lot, and people will generally expect that any computer scientist will understand how they work.
