代码说明：

说明：  Coordinate 组件库可被用于 坐标的变换 和 坐标系统的转换 等。 组件库又分成了两个子库：2D 和 3D，其中 2D 库用于平面坐标的处理，3D 库用于空间坐标的处理。(Coordinate component library can be used for Coordinate transformation and Coordinate system transformation. The component library is further divided into two sub-libraries: 2D and 3D. 2D library is used for processing plane coordinates and 3D library is used for processing space coordinates.)
