An axisymmetric coordinate system is essential for analyzing rotational systems.

分析旋转系统时，轴对称坐标系至关重要。

The point lies in the first quadrant of the Cartesian coordinate system.

该点位于笛卡尔坐标系的第一象限。

The z-axis completes the three-dimensional coordinate system with the x and y axes.

z轴与x轴和y轴一起构成了三维坐标系。

The transverse axis of the coordinate system is perpendicular to both the x and y axes.

坐标系中的横轴与x轴和y轴都垂直。
