摘要
在迄今为止的椭球大地测量学中,大地线是用微分方程表达的。该文在克雷洛定理的基础上,证明通过地心的平面对椭球体所截‘大圆弧'代表了一条大地线,进而得出大地线初等函数方程,并满足大地线的基本定义。
In ellipsoidal geodesy up to now,the geodetic line is expressed by differential equation. Based on Craylor′s theorem,this paper proves that the "big arc" cut by the plane of the earth's center represents a geodetic line,and then the elementary function equation of the geodetic line is obtained,which satisfies the basic definition of the geodetic line.
