摘要
对比了DSC与MDSC试验技术的差别 ,列举了MDSC的优点 ,MDSC不但可以给出普通DSC的所有信息 ,而且可给出更多的普通DSC无法提供的信息。MDSC特别适合于对复杂转变、弱的转变的分析 ,可以寻找出隐藏在熔融及结晶过程中的玻璃化转变。MDSC对于试验条件的选择比较苛刻 ,在选择好基本的试验参数的前提下 ,还需要设置调制周期。
A discussion on the merits and demerits of experimental techniques of the differential scanning calorimetry (DSC) is given, and the advantage of modulated DSC (MDSC)is emphasized, especially in the application to the detection and measurement of complex and weak transitions. It is reported that by the used of MDSC, the hiding glass transition temperature in the course of fusion or crystallization process can be detected. But the experimental conditions for MDSC are found to be more critical. In addition to the careful choice of the fundamental experimental parameters, the parameters of modulated period and modulated amplitude should also be carefully set up.
