| 摘 要： | The sticking probabilities of the activated chemisorption of CH_4 on Ni(111)surface are calculated by a quantum tunneling model at temperatures be-tween 300K and 4000K.The results show that the sticking probability increasesrapidly with increasing the surface temperature above 600K.The vibrationalenergy of CH_4 can effectively promote the dissociative chemisorption process onthe nickel surface,in which the bond stretch modes are prior to the deformationmodes.
