| 摘 要： | 介绍了灵敏度及温度校正对基线和实验结果的影响.仪器温度和灵敏度校正可以减小差示扫描量热法(DSC)曲线的漂移,曲线上得到的温度和焓变值更接近理论值,减小了实验误差.所以,定期对仪器进行重新校正是必要的. |
| 关 键 词： | 热分析 校正 基线 差示扫描量热法 |

| Abstract: | In this study, we describe the effects of the correction of temperature and sensitivity on the base line and the experimental results. The correction of temperature and sensitivity of the instrument can reduce the drift of the differential scanning calorimeter (DSC) curve. The differences between the measured values of temperature and enthalpy and the theoretical values are reduced and the experimental error is reduced significantly. Therefore, regular correction of the instrument is necessary. |
| Keywords: | thermal analysis correction base line DSC |
