摘　　要：用Tang-Toennies势模型和密耦近似方法计算了不同能量下惰性气体原子Kr与H2及其同位素D2,T2″替代碰撞体系的转动激发碰撞截面.结果表明,体系的约化质量及入射原子相对碰撞能量的变化均给体系的碰撞截面带来不同程度的影响。Tang-Toennies potential model and close-coupling method are applied to the Kr-H2 （D2,T＇2） system, and the rotational excitation cross sections at different incidence energy have been calculated. Based on the calculation, influence on the cross sections exerted by the variations in the reduced mass of the systems and in the relative energy of incident atom is discussed.
