1·Here we advance the concept of the effective sticking coefficient.

我们提出了有效吸附系数的概念。

2·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。

3·ZA27 alloy shows good mechanical properties and working properties. Small coefficient of friction and large sticking force to oil can substitute ZA27 alloy for Bronze alloy.

ZA27合金具有良好的力学性能和加工性能，它的摩擦系数小，对油的亲和力大，而且ZA27合金的综合性能突出。
