| 摘 要： | 给出了一种方便快捷的瞬变电磁全区视电阻率数值计算方法--逆样条插值法。对几例由2.5维正演程序获得的理论数据的计算结果表明，逆样条插值法用于全区视电阻率的定义是可行的。与此同时，该方法的实现也为瞬变电磁自动反演中初始模型的构制奠定了基础。

| Abstract: | A convenient and fast numerical calculation method of all-time apparent resistivity for the transient electromagnetic method --inverse spline interpolation method has been developed. Several conversion examples, from induced electromotive force through central-loop TEM2.5-D forward program to apparent resistivity, illustrate the feasibleness of inverse spline method. At the same time, the method has also laid the foundations of initial model definition in TEM automatic inversion. |
