Methods: the solid dispersion was prepared by solvent method. The solubility, the dissolution rate and the derivative thermogravimetry (DTG) were determined.
方法：采用溶剂法制备固体分散体，进行溶解度、溶出速率测定，导数热重分析(DTG)。
By employing the traditional method of thermogravimetry it is very difficult to accurately deduce the reaction mechanism of pyrolysis.
在利用热重法判断热解反应机理时，传统方法很难确切推断反应的机理。
