| 摘 要： | 在椭球面上建立一种特殊的坐标系——二面直角坐标系。在该坐标系中可以清楚、简单地表达任意法截面与子午面的夹角,且可以直观地表达任意法截线曲率半径的大小以及它们与法线的关系,通过比较分析阐述该坐标系的优点。

| Abstract: | A special coordinate syetem—two surface right-angle coordinate system was established on Ellipsoid in this paper.The angle between the arbitrary normal cross surface and the meridian surface could be expressed clearly and simply in this coordinate syetem.Also,the magnitude and the relation of the curvature radias of the arbitrary normal cross line to that of the normal line could be showed visually.The advantage of the coordinate syetem was illustrated by comparison and analysis. |
