The diffusion mechanism wherein net atomic migration is from lattice site to an adjacent vacancy 一種擴(kuò)散機(jī)制,這時候原子的凈遷移過程是從晶格結(jié)點位置移動到鄰近的空位中。
Contrasting with coating method , to produce samples by mixed aqueous solution of fe ( no3 ) 3 and a 1 ( no3 ) 3 will obtain a - a12o3 with a high percentage of isolated fe3 + ions in the lattice sites 與包覆方法制得的樣品相比,均勻摻雜法制備的樣品中固溶的fe ~ ( 3 + )離子較多。
Much theoretical work in lattice differential equations concerns one - dimensional lattices , often with weak coupling between lattice sites . by contrast , we are more concerned with lattice systems in two - dimensions 由于生物和電學(xué)( josephsonjunctions )的需要,人們對一維耦合振子鏈做了許多研究,其中包括許多理論的結(jié)果和數(shù)值上的分析。
