【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.更多还原
