DTA,TG,DTG techniques were used to study the thermal oxidation degradation process and kinetics of medicine (C 24H 29N 5O 8S) in air. We found that the thermal oxidation degradation process of medicine is in four steps.

• 用热重法 (TG)、微分热重法 (DTG)、和差热分析法 (DTA)研究药物甲磺酸多沙唑嗪 (C2 4 H2 9N5O8S)在空气流中的热氧降解过程和热氧降解动力学 ,发现该药物的热氧降解过程由四个紧连步骤组成。
