Like the counting function, when several aggregations with grouping keys are used in a rule, the group and count operations must be cascaded as shown in figure 14.

与计数函数类似，当在一个规则中使用多个具有分组关键字的聚合，对分组与计数操作必须进行级联，如图14所示。

Now, I hope you guys know that much calculus, that when you take a derivative of a function of a function, namely v square over 2 is a function of v, and v itself is a function of t, then the rule for taking the derivative is first take the v derivative of this object, then take the d by dt of t, which is this one.

我希望你们了解更多的微积分知识,当你对复合函数求导时,也就是说v^/2是关于v的函数,而v本身是关于t的函数,求导的法则应该是,第一步是这一部分对v求导,然后v再对t求导,得到这一部分
