It is also described that the incidence, the theory base, the applied scope, the steric blindness and the influence factor. 同时对发病率、理论基础、应用范围、影响因素进行了讨论。
The collision theory for chemical reactions is discussed and the probability function of reaction ( or steric factor) of different collision models is deduced for direct simulation of chemical gas flow. 论述了碰撞过程中的化学反应理论,给出了不同分子碰撞模型下的化学反应抽样几率函数(位阻因子)构造的过程。
