坐标系是部件空间位置的替代定义，对于检查器来说，该替代定义比部件空间位置的真实坐标更为方便。

Coordinate System is an alternate definition of a part's position in space that is more convenient for the inspector than its true coordinates.

本文采用基于三维空间坐标的功率理论，即三相电压对应到三维空间坐标中的三维空间矢量。

In this paper, three-phase voltage will be corresponded to the three-dimensional space vector in the three-dimensional space coordinate.

现在我们已经有了照相机，但是还要将3D空间影射到把三维空间坐标系转换到二维屏幕坐标系的“视口”上。

Now that we have the camera, we must map 3D space to a 'viewport' which handles the translation of coordinates from 3D space to the 2D screen.

For the simplest context in which one can motivate a vector and also motivate the rules for dealing with vectors, is when you look at real space, the coordinates x and y.

对于最简单的情况,我们能用矢量,以及相关的规则来处理的,是实空间,x-y 坐标系
