一概述从六十年代以来,由于科学技术的发展和商品热分析仪的出现,热分析方法有了迅速的发展,至今已广泛地用于矿物、冶金、化工和药物等多个领域中,成为科学研究和生产中重要的理化分析方法之一.热分析是用来确定物质的状态随温度变化的热效应关系,以表征物质在热过程中的物理和化学性质及其量的变化.差热分析法是热分析的一种.它是在恒压和勻速升温(或降温)条件下,作为温度的函数,来测定物质热焓的变化.
An overview Since the sixties, due to the development of science and technology and the emergence of commodity thermal analyzer, thermal analysis has developed rapidly, has been widely used in mineral, metallurgical, chemical and pharmaceutical and other fields, as Scientific research and production of one of the important physical and chemical analysis methods. Thermal analysis is used to determine the thermal effect of the state of matter with temperature changes in order to characterize the substance in the thermal process of the physical and chemical properties and the amount of changes in differential thermal analysis The method is a type of thermal analysis which determines the change in enthalpy of a substance as a function of temperature at a constant temperature and at a constant temperature (or temperature).
