The IRC result predicts that the transformation is one stepmechanism between two minimum and can occur at room temperature.
反应路径（IRC）分析表明，相邻最低点之间的相互转化为一步机理且在常温下可以发生。

The results also show errors in the predicted temperature and concentration distributions when using the one-stepmechanism, especially for the fuel-rich condition.
同时，单步机理预报的温度和浓度分布也存在较大偏差，特别是在富燃区。

This definition sounds like that of a transactional mechanism in a database management system, in which a step can be rolled back if it is not performed correctly.
