大量实验结果表明，惰性形核涂层的非晶化程度、熔体过热度、过热保温时间以及循环过热次数等工艺参数将显著影响熔体的初始过冷度。

The results point out that the values of kinetic parameters are altered with the addition of Ti and C, which change the crystallization type from difficult nucleation and easy growth pattern to easy nucleation and difficult growth pattern, and this difficult nucleation and easy growth pattern may be the main reason why fine and even microstructure is gained in Ti and C doped alloys.The influences of Nd content, B content, partial substitution of Nd by Pr on the microstructure and magnetic properties have also been researched.

文章从动力学理论的观点揭示了合金显微结构与合金晶化动力学特性之间的关系，指出Ti和C添加改变了Nd9.4Fe79.6B11合金晶相析出时的动力学参量值，使合金晶化时晶相的析出方式由难形核易长大型加热管转变为易形核难长大型，这种易形核而难长大的晶化动力学特征，是Ti和C添加合金获得细小均匀的纳米晶结构的根本原因。

与nucleation相关的网络解释 [注：此内容来源于网络，仅供参考]

nucleation：成核

(2)成核(nucleation)阶段,形成结晶微颗粒的作用称之为成核作用. (3)生长(growth)阶段,结晶微颗粒的表面逐渐沉积更多的固体,最后生长成为大型的晶体颗粒.

nucleation：成核(作用)

这样一来,要在只稍稍过饱和的液体中(包括香槟、气泡酒、啤酒及汽水皆是如此)形成气泡,就必需要有事先存在的气体空腔,而且空腔的曲率半径必须大到足以克服这个成核作用(nucleation)的能量障碍,气泡才可以自由地成长.

nucleation：成核现象

若持续加电压,液晶分子会倾向自由能较低的弯曲态排列情形,但弯曲态和斜展态在局部解剖(Topology)上并不相似,在转换时需要经过成核现象(Nucleation)来达成,液晶分子若是有部份转弯曲态,就可变成液晶盒内的转态核心,

nucleation：晶核形成

他们指出:"最为人所熟知的晶核形成(nucleation)的实例就是在云层中播种人造雨,与冯.内格特的故事可说如出一辙. "我1965年就认识冯.内格特了,当时我为>(Paris Review)访问过他. 听加德赛克提及'冰九',又读了柯毅和兰斯柏瑞的论文后,

nucleation period：成核期

feme [律]妇女, 妻, 女人 | nucleation period 成核期 | quiescent power drain 静态功耗
