热功当量实验中水的终温修正的研究
THE STUDY OF CORRECTION METHOD OF FINAL TEMPERATURE OF WATER IN THE EXPERIMENT OF MECHANICAL EQUIVALENT OF HEAT
【摘要】 本文通过对量热器中水的传热过程的理论分析和实验比较,证明应该用牛顿 冷却定律修正量热器中水的终温.
【Abstract】 Through the theoretical analysis of the heat conduction process of water in the calorimeter in comparison with experiments,the paper confirms that Newton’s law of cooling should be used to correct the value of the final temperature of water.
