物理大地测量学与地球物理学结合中的有关问题评注

SOME REMARKS ON COMBINATION OF PHYSICAL GEODESY AND GEOPHYSICS

本文依据大地重力学反问题的有关研究，对重力场边界扰动量的本征含义进行分析，由此揭示出它们在逼近地球实际重力场源过程中所具有的物理意义及存在的不足．然后进一步论及正常场源（参考椭球）的非物理性上，并对其解决途径进行了探讨．最后对大地重力学反问题研究中的理论核心一一正交分解定理描述的场源量所具有的实际意义及其在地球物理反演中所具有的作用进行了分析和评注．

An analyses is firstly madc about the origina1 definitions of disturbing boundary values of gravity fleld from geodesy, which rcveals the practical implications and indetermination when sucb boundary values are used into the inversion and explanation of internal anomaly density. Then the physical significance or resource dens1ty corresponding to the normal gravity field (reference ellipsoid) are discussed and some ways to solve the problems above are proposed. At last the substance of density functions given by the theorem of orthogonal decomposition in inverse gravimetric problem are analysed and the restrictions provided by this theorem to the geophysical inversion are remarked.
