基本解釋

It shows that the nucleus formation and crystal growth can be expressed as a first order reaction.
實(shí)騐表明，晶核生長(zhǎng)和晶粒長(zhǎng)大速率可以用一級(jí)反應(yīng)方程來(lái)表示。
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較快，而晶核生成後的成長(zhǎng)速度較慢，則生成的晶核數(shù)目較多，晶粒較細(xì)。
