摘要
对正常高改正公式中的重力异常改正项进行了积分置换。将原来主要依赖于沿水准路线的重力异常的公式置换为主要依赖于水准路线两端高程的公式,以更便于使用。同时对这一新的公式的精度、特点和应用作了评述。
:A new formula for the gravity anomaly correction on normal height has been derived. The original formula for gravity anomaly correction, which mainly depends on the gravity anomalies along the leveling lines, has been changed into what depends on the heights of the ends of the leveling lines. The new formula is easy for practical computation. In addition,the accuracy, behaviours and applications of the new formula have been discussed.
