Just as a snowflake requires a nucleus to spur the formation of its intricate crystal structure - a catalyst was required to spur the formation of the desired community.
一片雪花，必须有凝结核才能形成其复杂的晶体结构。在我们期望建立的群体中，同样需要这样的催化剂。

If the generation of the nucleation rate faster, and crystalnucleus 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。

Meanwhile, fine crystal discharge device was added in crystallizer to decline quantity ofcrystalnucleus and to increase crystal growth rate so as to reach the aim of improving crystalline quality.
