摘　　要：针对目前实验测量液体比热容时存在的操作步骤复杂、计算工作量大、结果不精确等一些问题,介绍了一种利用实验曲线积分对液体比热容进行计算及散热修正的新方法。采用此方法,可以在测量描绘升温曲线的基础上精确地对测量液体的比热容进行散热修正与计算。实验结果表明,此方法不但省去传统方法中自然降温的过程,简化实验步骤,而且提高计算结果的精确度。For some existing problems in the specific heat of liquid correction method, this paper pres- ented a method to finish the thermal dissipation＇s correction, and calculate the specific heat. During the measurement of liquid specific heat by electric heating, this method could calculate the specific heat and amend it based on the measured temperature curve integral of the heating process accurately and effi ciently. The results showed that the new method not only eliminated cooling process for traditional method, simplified the experimental procedures,and also improved the accuracy of the result.
