结果，显示第二层工作项的该方法可以节省大量的时间(查看图6获得更多的具体信息)。

As a result, this method for displaying second level work items can save a lot of time (See Figure 6 for details).

每个元组的第一项是可调用对象（在这里是一个方法指针），第二项是 HTTP 请求类型，这种请求类型可以调用该方法。

The first item in each tuple is a callable object (in this case a method pointer) and the second is a HTTP request type that the method should be called for.

顺便说一下，这里这个-号实际上和，我们做交叉乘积的时候的方法是有联系的，我们在算第二项前面是-号。

By the way, this minus sign here is actually related to the way in which, when we do a cross product, we have a minus sign for the second entry.
