摘　　要：用Ｍｏｎｔｅ＿Ｃａｒｌｏ轨迹法研究了Ｈ（２Ｓｇ）＋ＣＮ（Ｘ２∑＋）体系的非反应碰撞传能方式、变化规律及其与反应过程的竞争能力．得知：在ＣＮ（Ｘ２∑＋）处于振转基态Ｖ＝０，Ｊ＝０时，非反应碰撞主要发生Ｔ→Ｒ传能，次要发生Ｔ→Ｖ传能；当Ｖ＝１，Ｊ＝０时，该碰撞主要发生Ｖ→Ｔ传能，次要发生Ｖ→Ｒ传能．当ＣＮ（Ｘ２∑＋）随振动态由Ｖ＝０→１变化。In H( 2S g)+CN(X 2∑ +) the way of transference energy in the nonreaction collision,the rule of variances in the way and the ability of competition with the reaction collisions have been studied with Monte_Carlo trajectory method in this paper.It has been known that when CN(X 2∑ +) is in the vibration-rotation ground state V=0 and J=0,T→R is a main way of transference energy in the nonreaction collision,and T→V is a secondary way,when V=1 and J=0,V→T is a main way and V→R is a secondary way in it.When the vibration state of CN(X 2∑ +) is changed from 0 to 1,the competition ability of nonreaction collision is strengthened obviously.
