五十年代以来,人们采用了各种热分析法研究固体热分解反应动力学。如等温法,不等温法和循环加热法;热重法(TG),微分热重法(DTG),差热法(DTA)和差示量热法(DSC);单图法,双图法和多图法。到了七十年代,不仅常常将上述方法综合应用,而且在处理数据方面,逐渐趋向了“试差法”。其实,固相反应过程,既使是最简单的热分解:A(s)→B(s)+C(g)↑,也是相当复杂的。既涉及物质及其反应的内在特性,(如键的断开,原品格的破坏,新品格的形
Since the 1950s, a variety of thermal analysis methods have been used to study the kinetics of solid thermal decomposition. Such as isothermal method, non-isothermal method and cyclic heating method; TG method, DTG method, DTA method and DSC method; single map method, double map method And multi-graph method. In the seventies, not only the above methods were often applied in a comprehensive way, but also the “trial and error method” was gradually applied in data processing. In fact, the solid-phase reaction process, even the simplest thermal decomposition: A (s) → B (s) + C (g) ↑, is quite complicated. It involves both the intrinsic properties of the substance and its reactions, such as the breaking of the key, the disruption of the original character, the shape of the new character
