摘要：
Oxygen adsorbed on Pt stepped surfaces has been studied by means of the 5-parameter morse potential (5-MP) of interaction between an adatom and metal surface cluster. The theoretical calculated results about O/Pt (s) - [n(111) x (100)] systems draw some conclusions. The four-fold site behind a step that an oxygen atom binds in corresponds to the most stable state named beta(2)-state. And the three-fold site near the four-fold site at a (111) terrace is annihilated, then the other three-fold sites correspond to adsorption states named beta(1)-state. In addition the length of the (111) terrace has effect on the four-fold state.
