摘要

摘要本文研究了离散重力势理论中拉普拉斯方程网格模拟基本解的唯一确定问题。拉普拉斯方程的有限差分模拟的网格基本解在从某一网格集各点获得的异质和不同精度的数据重建连续分布的引力场或磁场源方面起着关键作用。

On the Uniqueness of Determining the Mesh Fundamental Solution of Laplace’s Equation in the Theory of Discrete Potential

Abstract

The paper examines the problem of unique determination of the fundamental solution of a mesh analogue of Laplace’s equation within the theory of discrete gravitational potential. The mesh fundamental solution of the finite-difference analogue of Laplace’s equation plays a key role in reconstructing a continuously distributed source of gravitational or magnetic field from heterogeneous and different-precision data obtained at points of a certain mesh set.
