The diffusion mechanism wherein net atomic migration is from lattice site to an adjacent vacancy 一种扩散机制,这时候原子的净迁移过程是从晶格结点位置移动到邻近的空位中。
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 与包覆方法制得的样品相比,均匀掺杂法制备的样品中固溶的fe~(3+)离子较多。
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 由于生物和电学(josephsonjunctions)的需要,人们对一维耦合振子链做了许多研究,其中包括许多理论的结果和数值上的分析。
