全时域时间谱视电阻率算法研究

A STUDY OF THE ALGORITHM OF THE FULL TIME DOMAIN APPARENT RESISTIVITY

本文采用数值逼近的方法，逐段用多项式表示偶极—偶极排列的瞬变电场。根据求出的多项式指数和系数，建立全时域时间谱视电阻率的算法。该算法能对小收发距（ｒ与ｈ１相近或更小）时的瞬变电场，计算出可形象反映地电断面的视电阻率。

By use of numerical approximation method, the paper uses the polynomial to approach segmentally the transient electric field from dipole dipole array. Based on the computed factors and exponents, the algorithm of the full time domain apparent resistivity is established. Apparent resistivity curves, which are drawn in the light of the computed results by this algorithm, can generally vividly reflect the geoelectric section when the space between reciever and transmitter is less (r is close to h 1or less).
