初中物理第二册中研究物质的比热实验，常受条件的限制，而不易成功。我们经过多次试验，对该实验装置做了改进。1实验器材①两只相同的小酱菜罐头瓶；②相同的温度计两支，两只橡皮塞；③玻璃水槽（或塑料水槽）一只；④量杯（或量简）一只，容量200mL；⑤煤油（不少于200g）
The specific heat experiment of the research material in the second book of junior middle school physics is often limited by conditions and is not easy to succeed. After many experiments we made improvements to the experimental apparatus. 1 laboratory equipment 1 two identical small pickle cans; 2 identical thermometers, two rubber stoppers; 3 glass sink (or plastic sink) one; 4 measuring cups (or Jane) one, capacity 200 mL; Kerosene (not less than 200g)
