自从氢气回收和富氧分离大规模工业化以来,人们对气体在膜中的渗透机理进行了大量的研究。
Since hydrogen recovery and oxygen enrichment are industrialized on large scale, a lot of researching work have been done on gas permeation mechanism in membrane.
Under the spark discharge treatment, the structure of the anodic layer was significantly changed, the enrichment of silicon and oxygen was enhanced, and the surface potential was ennobled.
