摘要 

为了在三维不规则起伏观测曲面上直接进行高精度重磁位场延拓,本文提出了两种精度高、适应性强、计算速度快、分块处理误差小且易于在微小型计算机上实现的位场曲面延拓方法--三角函数法和偶层位法。通过理论模型试算和实际资料处理,验证了本方法及其软件的正确性及可靠性。

Abstract

For the purpose of performing direct continuation of high-precision gravityand magnetic potential field on the three-dimensional irregularly undulateobservational curved surface, this paper puts forward two continuation methodsfor potential field curved surface, i. e. trigonometric function method and evenposition method, which are characterized by high precision, strong adaptabili-ty, high computation speed, negligible error in block processing and easy reali-zation on microcomputer. Tentative calculations on theoretical models andprocessing of practical data prove the correctness and reliability of these twomethods and their softwares.
