The paper extends a mathematical model for point-source electrical stimulation of a nerve. In the original model, it was assumed that all the axons in the nerve have the same diameter. In this paper the model is extended to represent a nerve with an arbitrary distribution of axon diameters. It is shown that the assumption of identical axons is justified for a typical human nerve if the 'representative' axon diameter is taken as the area-weighted average of the diameter distribution.
本文扩展了一种用于神经点源电刺激的数学模型。在原始模型中，假定神经中的所有轴突具有相同的直径。本文将该模型扩展为表示具有任意轴突直径分布的神经。结果表明，如果将“代表性”轴突直径视为直径分布的面积加权平均值，则对于典型的人类神经而言，轴突相同的假设是合理的。
