PSR DZ error DZ 输入信号毛病
dz But, if you do dz first, then the inner bounds are given by bottom and top, and the outer ones are given by looking at the shadow of the region.
如果你先处理,那么内部的边界就被底部和顶部给定,并且外部的边界也可以通过观察这个区域的阴影得到。
Or, it tells you actually anything you might want to know about the relations between these variables so, for example, you can move dz to that side, and then express dz in terms of dx and dy.
事实上它告诉了我们,任何的关于这些变量之间的关系,例如,可以把dz移到另一边,用dx和dy来表示。
Well, we can do that in rectangular coordinates dz dx dy where dV becomes something like, maybe, dz dx dy, or any permutation of these.
我们在直角坐标系中处理,在这里dV有可能变成,或者它们的其他排列。
