摘　　要：气相化学反应动力学方程中,反应物质浓度随时间的变化率对应有浓度速率系数,反应物质压力随时间的变化率对应有压力速率系数。依据浓度与压力2种速率系数的关系,由阿仑尼乌斯方程得出了2种速率系数对应的活化能间的关系,并验证了该关系式的正确性,分析了该关系式的使用条件。In the kinetic equation of gas phase reaction, the rate of the reaction expressed as the rate of change of the concentration of the species corresponds to a concentration-rate coefficient, and the rate of the reaction expressed as the rate of change of the pressure of the species corresponds to a pressure-rate coefficient. According to the relation between concentration-rate coefficient and pressure-rate coefficient, relationship between the two types of activation energies corresponding to different rate coefficients are deduced by use of Arrhenius equation, the correctness of the relation are proved and the application conditions of the relationship are concluded.

关 键 词：浓度速率系数 压力速率系数 活化能
