description	<正> The adsorption kinetics of gaseous molecules on solid surface is the fundament of the im-portant techniques such as the heterogeneous catalysis and the molecular beam epitaxy.Usu-ally it is studied through the functional relationship of the sticking coefficient(S)ofmolecule adsorption to its coverage(θ).For the simple chemisorption,S(θ)=S~0(1-θ),which is the well-known Langmuir adsorption kinetics.For a pure physisorption,S(θ)is
