If the generation of the nucleation rate faster, and crystal nucleus formation, growth speed is slow, it generated more cell number, grain is fine.
如果晶核的生成速度较快，而晶核生成后的成长速度较慢，则生成的晶核数目较多，晶粒较细。

That is, in electroplating process when the generation of the nucleation speed is greater than the growth of the nucleation rate, it can get meticulous, crystallization of closely spaced coating.
也就是说，在电镀过程中当晶核的生成速度大于晶核的成长速度时，就能获得结晶细致、排列紧密的镀层。

Effects of the specific pressure on nucleation rate and linear growth velocity were expounded in squeeze casting.
