摘 要:本文探讨了常用的几个计算重磁垂直二阶导数公式的内在联系,并从这些联系规律出发导出了三个新的公式。阐述了频率域判别计算二阶导数公式优劣的合理标准。并用理论模型计算证实频率域用频响特性的最佳值判别的合理性及新导的三个公式的实用价值。
Abstract: The inward relation among some formulae which are often used to compute the vertical second-order derivatives of the fields of gravity and magnetism is discussed,and so three new formulae are introduced in this thesis.The new standards which can judge what are merits and demerits of these formulae in frequency-domain are expounded.It is verified that the optimum distinguished method of frequency response is reasonable and the given new formulae are useful in frequency-domain by means of the compu- tation of the theoretical models.
