我可以要求返回它的极坐标形式，这里对我是可访问的，好，这很棒，请再记另外一个为什么。

So for example I defined p, remember back over here, as a Cartesian point, but I can actually ask for its polar form.

如果我现在说，我要去改变这里的半径，一些这样的操作，我的极坐标形式，进行了正确的改动？

If I now say, I'm going to go ahead and change the radius of this, something, my polar form did it right, but what happened to the Cartesian form?

在直角坐标形式电流注入型潮流算法的基础上，结合电力系统的实际，推导出了极坐标形式的电流注入型潮流算法。

On the basic of the rectangular current-injecting power flow algorithm and practice of power system calculation, this paper presents the polar current-injecting power flow algorithm.

Right, and just to get a sense of this, let's look at a simple little example, so on your hand-out, you'll see I've got a little piece of code that says assuming I've got one of these points, I want to do things with it, for example I might want to add them together.

这些数组中的一个，你怎么能够知道，它是哪种类型的呢？,你怎么知道它是以笛卡尔坐标,表示的还是以极坐标,形式表示的呢？,你没有可以用来区分的东西，你没有说明这种信息,聚集实际上的意义。
