the steep change of the sticking coefficient in the temperature range 110-120℃ may be explained by a model of the order-disorder transition arisen from the surface melting.
在110—120℃温区内发生的粘着系数的阶跃变化可以用表面熔化所导致的有序-无序的相变模型来解释;
it is shown that the sticking coefficient of oxygen on ag-pd alloy surface is slightly less than that on ag surface, which implies that the alloying of ag and pd decreases the surface activity.
与纯银相比,氧在银钯合金表面吸附具有较小的粘附系数和较大的偶极矩。
the initial sticking coefficient of the k precovered ag surface for oxygen adsorption is enhanced.
