一、表面吸附 1·1固-气界面 空间的气体分子在运动中与固体表面相碰时,分子或是由表面弹性反射;或者是附着在表面上一些时间,然后逸回空间(离去的方向与入射方向无关)。在大多数情况下,碰撞表面的分子都在界面上停留一定的时间。此时间的长短取决于气体分子与表面相互作用的一 First, the surface adsorption 1.1 solid-gas interface gas molecules in motion with the solid surface collision, the molecules are either surface elastic reflection, or is attached to the surface for some time, and then escape to the space Direction and incident direction has nothing to do). In most cases, the molecules that collide with the surface remain in the interface for a certain amount of time. The length of time depends on the interaction of the gas molecules with the surface
