RESULTS It was found that the pyrolytic degradation kinetics of sodium ferulate injection corresponded with the first-order kinetics. The expiration dates of the injection calculated by two different methods were 1.72 and 1.90 years. 结果阿魏酸钠注射液的降解动力学过程符合一级动力学过程,用经典恒温法和多元线性模型预测阿魏酸钠注射液的有效期分别为1.72、1.90年。
