近来,为研究毛角朊的热效应,在采用各种膨胀测定法的同时,更广泛地采用了微分热分析的方法。运用这些方法可以在加热时固定研究样品的温度差和研究温度与时间作用的关系。但是,为了更广泛地使用这种方法必须准确地了解角朊热效应的性质。本文的目的就是为了研究这些问题。 Recently, in order to investigate the thermal effect of keratin, differential expansion analysis has been used in a wide range of ways. Using these methods, the temperature difference between the samples and the relationship between the temperature and the time can be studied experimentally while heating. However, in order to use this method more widely, the nature of the heat effect of keratin must be accurately understood. The purpose of this article is to study these issues.
