摘　　要：国内外一些物理化学教材对焦耳实验结果进行了分析推论 ,并应用到热力学第一定律 ,对于dT =0的结果分析 ,其推论都概括为是由于等温过程 ,体系与环境之间没有热量交换 ,所以Q =0 ,这种对实验结果的分析是不够科学也是不完善的 ,对此笔者提出几点不同看法 ,并进行了修正。Some “Physics Chemistry”textbooks both home and abroad have always analyzed and deduced Joule's experiment result by applying the First Law of Thermodynamics.However,for the case of d\%T\%=0,the summary of their analysis and explaination is that the reason why \%Q\%=0 is that there is no heat exchange between the system and the environment during the process because of “the constant temperature process”.We have some different point of view on the explaination which we think is not so scientific and perfect.Also,we have made some improvement on it.
