关千ΔT磁异常的解释

本文对于二度问题证明了总磁場强度△T与垂直磁場强度Z的一般表达式具有相同的形式,因此可以把△T异常曲线看成Z异常曲线,利用复变函数理论中的柯西-黎曼条件我们就可根据△T异常曲线计算出与H异常曲线相当的所谓△T的“负共轭调和函数”△T,文中指出了同时利用△T及其原函数△T将有助于磁测资料的解释工作,还举出了两个应用的例子:1)根据△T与△T计算二度体的磁矩及其倾角;2)利用观测水平上的△T及△T值将△T向下解析延拓。

THE INTERPRETATION OF MAGNETIC ANOMALIES △T

It is proved, for the two-dimensional question, that the general expression of total intensity △T has the same form as the vertical intensity Z. There is a possibility to consider the anomaly curves △T as Z. Therefore by use of the Cauch-Riemann's condition in the theory of function of a complex variable we may from anomaly curves △T calculate its so called "negative harmonic conjugate function" （） which is corresponding to the anomaly curves H. It is indicated that interpretation of the magnetic data may be facilitated by ussing （） together with its original function △T. Two examples of application are given: 1) the calculation of the magnetic moment and its inclination for two-dimensional bodies from △T and AT; 2) downward analytical continuation of △T by use of values of △T and △T on the horizon of observation.
