摘　　要：准确计算温差值是量热法实验的关键。为了消除热传递和搅拌带来的影响,通常采用雷诺温度校正图的办法来对测量的温差进行校正。本文以燃烧热实验为例,详细介绍了运用Origin软件的积分功能对雷诺校正图采用等面积法来确定体系温差值的方法。此法体现了雷诺校正的本意,提高了实验的准确度,更有利于学生加深对雷诺校正原理的理解。Accurate calculation of temperature differences is the key to calorimetric method.In order to eliminate the influence of heat transmission and stirring,Reynolds correction method is usually used to rectify the measured temperature differences.Taking the experiment“heats of combustion”as an example,the processing method of Reynolds correction curves using equal-area method by“Integrate”tool of the Origin software to determine the temperature differences was introduced in detail,which reflects the original intention of the Reynolds correction,improves the accuracy of the experiment,and deepens students'understanding of Reynolds correction.
