According to mass spectrum analyses it has been deduced qualitatively that H2O CH4 and CO ( CO2 ) are produced from zero-order surface reaction multi-step synthetic surface reaction and collision surface reaction respectively .

质谱分析定性地指出，主要气相杂质H2O来自 零 级表面 化学 反应，CH4来自多步骤合成表面化学反应，CO（CO2）则来自碰撞表面化学反应。

The results showed that 83.83 % of nicotine was degraded in 36 h the degradation process of nicotine followed zero-order reaction of Monod model .

结果表明，36h烟碱降解率为83.83%，其降解过程符合Monod模型的 零 级 反应，动力学方程为：C（t）
