| 摘 要： | 本文利用回归分析、谐波分析和预测、理论研究了从大地电位差(Vsp)和人工电位差(ΔV)迭加的合成势差(E)中高精度分离ΔV的方法。实际计算表明:当Vsp变化规律较强时,该方法的精度比常规方法提高几倍至十几倍;当Vsp变化规律较弱时,该方法的精度一般高于或接近于常规方法的精度。

| Abstract: | This paper studied a high precise method separating artificial potential difference Δv from the potential difference E which is synthesized With the geoelectric potential difference (Vsp) and Δv on a basis of regressive analysis, harmonic analysis and prediction theory. Lots of the calculation result show:If the changes in Vsp are more regular, the calculation precision through the method is obviously higher than that through the conventional methods; If the changes in Vsp are less regular, the precision through the method is higher than (or close to) that through the conventional methods. |
