摘要
研究了大地奇异性对大地测量的影响及重力场在大地奇点附近的结构,揭示了奇异性的本质。
In the paper the authors have studied the influence of the geodetic singularity on geodesy and the structure of the gravity field near the singular point, exposed the nature of the singularity, and drawn the following conclusions: reference Isolated geodetic singular points are removable; reference Under the condition that Gauss curvature of equipotential surface is non negative and geodetic torsion of meridian vanishes. If there exist geodetic singular points on the equipotential surface of the earths gravity field, their number is finite and they are isolated.
