从包含任意电阻组合和具有与频率无关的恒定相角的单个可变阻抗元件的电网理论出发，证明了终端串联电抗对电阻的图是一个圆弧，圆弧的中心位置取决于可变元件的相角。如果假设生物系统等同于这样一个网络，那么红细胞、肌肉、神经和马铃薯的低频和中频数据支持了这些假设。对于某些组织，在高频处与圆有明显的偏离，这是无法解释的。
From the theory of an electric network containing any combination of resistances and a single variable impedance element having a constant phase angle independent of frequency, it is shown that the graph of the terminal series reactance against the resistance is an arc of a circle with the position of the center depending upon the phase angle of the variable element. If it be assumed that biological systems are equivalent to such a network, the hypotheses are supported at low and intermediate frequencies by data on red blood cells, muscle, nerve, and potato. For some tissues there is a marked divergence from the circle at high frequencies, which is not interpreted.
