摘　　要：通过差示扫描量热仪研究调制DSC(MDSC)技术在比热测试中的应用,该实验分别对差示扫描量热仪进行常规校正、比热校正以及MDSC校正。校正后分别用Q2000直接测比热和MDSC测比热的方法测试了标准物质(蓝宝石)的比热,与标准值进行比对,MDSC的测试结果更接近标准值。通过数据分析,MDSC既简单又准确,展现MDSC在测试比热方面的优越性。The application of modulated DSC(MDSC)technology in the specific heat measurement was studied through the differential scanning calorimeter.This experiment conducted the conventional calibration,specific heat calibration and MDSC calibration on the differential scanning calorimeter.After calibration,the specific heat of the standard material(sapphire)was tested by the Q2000 direct measurement method and MDSC measurement method separately.Compared with the standard value,the MDSC measurement was closer to the standard value.Through data analysis,MDSC method was simple and accurate,demonstrating the superiority in measuring specific heat.
