摘要
本文是我们建立一种心阻抗血流图技术新理论的系列研究之一，是正式论文的简要快讯。本文旨在判明常用电阻公式是否适用于心阻抗血流图模型。本文研究了套在园柱形均匀导体侧表面一对接到恒流源上的供电电极在此园柱体内产生的电势、电流以及套在园柱体侧表面另一对测量电极测得的电阻；最后将所谓电阻公式与常用电阻公式作了对比。
The paper
is the first part of a series of investigations which have a finalgoal to establish a new theory of
impedance rheocardiogram,It is a concise research note ofour formal article,It is for the
purpose of judging the reasonableness of common resistanceformula in the model of
impedance rheocardiogram. A pair of circular electrodes connecting toa constant current source
is slipped on the side surface of a uniform cylinder conductor.Thepotential,current which both
are produced by the electrodes in the cylinder conductor wereinvestigated.Lastly,the new
resistance formula obtained by us was contrasted with commonresistance formula.
