| 摘 要： | 用镜象法并考虑实源与虚源的相互作用,给出均匀电场中水平圆柱体的视电阻率精确表达式。利用线性数字滤波法计算了几种不同条件下埋藏水平圆柱体上的激电响应时间谱。重点讨论了充电导数时间谱的计算结果,并与放电时间谱作了对比。

| Abstract: | According to the method of mirror images and taking into account theeffects between the real source and the virtual source, the accurate exp-ression of apparent resistivity has been obtained for a underground hori-zontal cylinder in uniform electrical field.Using the expression and the filtering method, we have figured out IPresponse of a buried polarizable cylinder in time domain for several situa-tions. We have mainly discussed the calculative results of the derivativecurves of charge (?V(T)/?LnT and ?LnV(T)/?LnT ), and compared themwith the decay curves in time domain. |
