| 摘 要： | 介绍一种称作TOPEM的温度调制差示扫描量热技术1],由瑞士梅特勒-托利多公司开发.该技术基于随机温度调制,是一般温度调制DSC理论的结果.无需进一步校准,在单次实验中就能测定准稳态比热和宽频范围的频率依赖的复合比热.而且,从测试的数据可直接测定可逆和不可逆热流,并可从热力学上将这两个热流分别与显热流和潜热流相关联.应用实例显示了TOPEM实验的线性行为测试和稳态测试(一致性检查)、玻璃化转变的频率依赖性、热固性树脂的等温固化、固-固转变、可逆熔融和不可逆熔融等.

| Abstract: | A temperature-modulated differential scanning calorimetry called TOPEM which is developed by Swiss Mettler-Toledo is introduced in the present paper~ 1] . The technique is based on stochastic temperature modulation and has been developed as a consequence of a generalized theory of a temperature-modulated DSC. The quasi-static heat capacity and the frequency-dependent complex heat capacity can be determined over a wide frequency range in one single measurement without further calibration. Furthermore,the re... |
