我读了一九五二年十月本刊第二卷第四期内所载的陈德云同志的“我怎样教初中物理实验课”一文以后,觉得他所布置的实验九“水的混合温度”,有提出讨论的必要。陈同志说:“在热学中课本没有配合实验,我们在此增添一个最基本的实验,是测量水的混合温度,通过这个实验,学生对于水温度降低丢失热量温度升高吸收热量,了解十分深刻”,的确在教学上有很好的收获,然而,他所设计的记录和计算格式 After reading the article entitled “How can I teach Junior High School Physics Experiment Class” contained in Comrade Chen Deyun, which was published in Volume II, Number 4 of October, 1952, I feel that the experiment 9 “Mixing Temperature of Water” There is a need for discussion. Comrade Chen said: "In the heat textbooks do not cooperate with the experiment, we add a basic experiment here is to measure the water mixing temperature, through this experiment, students lose water to reduce the temperature of the heat absorption of heat, understand very profound Indeed, there is a good teaching gain, however, he designed the recording and calculation format
