| 摘 要： | 设计研制了一种具有可视化功能的差示扫描量热装置,简称可视化DSC装置。该可视化DSC装置能够在差示扫描测量的同时,通过配套使用的显微镜摄像系统对测试样品的微观结构变化进行观察并记录。采用纯水为标准物质,对可视化DSC装置的温度测量与热量测量分别进行了校准,结果表明具有较高的测量稳定性。该可视化DSC装置能同时提供测试样品的热效应数据和微观结构的图像数据,提高了数据获取的同步性与测量结果的准确性。

| Abstract: | A differential scanning calorimetry(DSC) device equipped with a cryomicroscope was designed and built,which was hereafter called optical DSC system.The optical DSC system allows continuous microscopic viewing and recording the change of microstructure of the tested sample during DSC protocols.The optical DSC system was tested and calibrated by measuring the melting temperature and the latent heat using purified deionized water as a standard material.The results of the calibration experiment show high replic... |
