摘　　要：运用不同的方法理论研究了N++H2→NH++H反应的动力学性质.研究表明,该反应是一种吸热反应,并且在低温下不具有反应自发性.用3种方法计算了该反应在1 mbar的压力和在1 K和2 000 K温度范围内的动力学性质.通过研究发现这种反应在低温下反应机率很小,并且反应随着温度的降低而急剧减弱.并将本文的计算结果和实验结果进行了对比,发现计算结果与实验结果符合较好.研究表明:在低温条件下,反应物氢分子的转动动能对反应速率并不产生有效的影响.The kinetic properties of N^＋ ＋ H2 → NH^＋ ＋ H reaction have been studied theoretically. It is found that this reaction is an endothermic reaction and cannot react forward spontaneously under low temperature. The kinetic properties of reactions are calculated using three methods at a pressure of 1 mbar and a temperature ranging from 1 to 2000 K. It is found that this reaction has very low reaction rates under low temperature, and the rate decrease drastically fast with decreasing temperature. The results are compared with various experiments. An analysis of the free energy of activation of this reaction dependence of the hydrogen reactant rotational energy yields an assumption that the hydrogen reactant rotational energy does not affect the reaction rate coefficient under low temperature.
