摘 要：
根据对两种电源模型在内阻趋于零和无穷大时伏安特性变化趋势的分析,指出通常对电源模型等效变换理解存在的歧义,全面、准确的理解应是理想电压源不能等效变换为电流源,理想电流源不能等效变换为电压源。

摘 要：
According to an analysis of variation trend of voltage current characteristic of two power models when the internal resistance approaches zero or infinity,this paper points out ambiguity that exicts usually of understanding equivalent transformation of power models.A comprehensive and accurate understanding should be an ideal voltage source cannot be equivalently transformed into a current source and an ideal current source cannot be equivalently transformed into a voltage source either.
