一、吸气剂的吸气三因素 吸气剂的吸气是一个复杂的物理的和化学的过程。例如,吸气剂蒸散时金属蒸汽与气相分子的碰撞;气相分子与蒸散薄膜,菲蒸散吸剂表面之间物理的和化学的作用;以及吸附相分子(或原子)在吸气剂内部的扩散、渗透和固溶等等,都是造成气体被吸着的原因。通常认为,吸气剂的吸气大致有三个主要的,并且互相联系的作用因素:蒸散吸气(非蒸散吸气剂除外);气相分子的表面吸附(物理吸附和化学吸附);吸附相分子(或原子)的扩散(表面扩散和体扩散)。
First, the getter inhalation Three-factor getter inhalation is a complex physical and chemical processes. For example, the collision of metal vapor with gas phase molecules during the evacuation of the getter; the physical and chemical interaction between the gas phase molecules and the surface of the evaporimeter, the evaporimeter, and the diffusion of adsorbed phase molecules (or atoms) inside the getter , Infiltration and solid solution, etc., are caused by the gas being sucked. It is generally accepted that there are generally three main and interconnected factors for getter inspiratory: evaporative inspiratory (except non-evaporable getters); surface adsorption (physical adsorption and chemisorption) of gas phase molecules; adsorption phase molecules (Or atoms) diffusion (surface diffusion and bulk diffusion).
