摘　　要：通过对量热仪热容量的稳定性进行跟踪以及对标准物质的热值测试,探析点火热的固定值校正与实际消耗量校正对测定结果的影响,以确定仪器的准确度和控制方法。对2台不同型号的量热仪进行为期3个月的跟踪测试表明,量热仪的热容量稳定性好,苯甲酸和标煤的测定结果准确度满足要求,不同型号仪器间的测定结果无显著性差异;对点火热采用固定值校正与实际消耗量校正测定结果的比对,可以得到采用点火丝固定值校正对测定结果产生的误差基本可忽略之结论。By tracking the calorific capacity stability and testing the calorific value of standard material, the effect of ignition heat calibration methods on determination result was analyzed to determine the accuracy of the instrument and control method. The track test results showed that calorimeter stability was good, the accuracy of determination result of benzoic acid and standard material meet the requirements, there was no significant difference between different instruments. Comparison between fixed value calibration and actual consumption calibration of ignition heat showed that the error through fixed value calibration can be ignored.
