本文指出教科书中与能斯特公式相关的多种示意图是不等效的，其中一些可接受的，一些是不完善的，一些是不正确的.进而给出能斯特公式相关的完整示意图，可弥补多本教科书中的不足之处.所得结果有助于加深对能斯特公式的理解和对低温化学反应的了解.

It is pointed out that the various schematic diagrams related to Nernst’s equation in textbooks are not equivalent, some of which are acceptable, some are imperfect, and some are incorrect. Moreover, the complete schematic diagrams related to Nernst’s equation are given to remedy the deficiencies in many textbooks. The results obtained are helpful to deepen the understanding of Nernst’s equation and low-temperature chemical reactions.
