| 1. | The reason of this may be as follows , firstly , the model has not including some important physical process such as gap effect , wall quenching extinction effect , which may greatly influence the emissions ; secondly , the emissions formation in the cylinder are not all of equilibrium process but the process controlled by the chemical kinetics
原因之一是本模型未考虑诸多对排放具有显著影响的物理过程，如缝隙效应、壁面激冷淬熄效应等，其次说明发动机的缸内的过程并不全是平衡过程，许多排放物的生成受化学反应速度，即化学动力学的控制。 |
