| 摘 要： | 本文对调和性扰动重力场源的有关理论问题进行了推演，论证和分析。从理论上论证了在构制为外部赋值时的等效场源或向地球物理实际场源逼近中，调和性扰动场源所具有“最小模”性质。为人们选择调和性扰动场源作为大地重力原反问题研究的基本量提供了理论依据。

| Abstract: | The problems on harmonic density resources of disturbing gravity field are discussed and researched.It is proven firstly that harmonic density has the minimum norm among all the e quivalents of the first degree approximation density resources corresponding to a given external disturbing gravity field.And then the equivalent relation between closed(explict) solution and spectral representation on harmonic density given by different researchers is proven and analysed. |

| Keywords: | Harmonic density resource Minimum norm Equivalent relation |
