直流電沉積時,基質金屬的沉積連續進行,粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附,重新回到溶液中;採用周期換向脈沖時,反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附,同時,反向脈沖電流對基質金屬的溶解作用,也會促進粒子的脫附,因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加,三種鍍層的晶粒都明顯細化,說明al _ 2o _ 3的存在阻止了晶粒的長大,提高了電沉積過程中晶核的形成速率。Based on the diopter status of myopia and hypermetropia, the paper presented the principle of excimer laser refractive surgery, the change of impacting cornea curvature on the cornea diopter. in this chapter, we also discussed excimer laser - corneal tissue interactions and photoablation. determine the relationship between the fluence of arf excimer laser and the cornea ablation rate, attain the relationship between the energy density and the ablation depth
