1、vesicle nucleation───囊泡成核
1、Even at large undercooling, nucleation during solidification is usually controlled by a heterogeneous process.───即使是在大冷，核凝固过程通常是由一个非均质过程。
2、supersaturation used is too low to produce an appreciable rate of nucleation.───的过饱和度太低，不能产生一个值得重视的成核率。
3、Effects of the specific pressure on nucleation rate and linear growth velocity were expounded in squeeze casting.───阐述了挤压铸造比压对形核率及成长线速度的影响。
4、Since the phase transition and nucleation are microscopic processes, the experimental study of these processes is difficult.───相变和成核都是微观过程，实验研究较为困难。
5、Special development curves of pressure showed that nucleation was not always essential for the complete growth of hydrate crystals.───实验表现出来的特殊的压力变化曲线和规律还表明晶核形成对水合物晶体的生成并非绝对重要。
6、The heat treatment process and effects of the nucleation agent on the nucleation and crystallization were explored.───探讨了微晶玻璃的热处理工艺制度及晶核剂对核化、晶化的影响。
7、relationship between nucleation temperature and flexural strength was investigated.───探讨了核化温度与抗弯强度之间的关系。
8、Adopting the method of the invention is capable of accurately obtaining the best nucleation temperature and the best nucleation time.───采用本发明的方法能准确地获得最佳的核化温度和核化时间。
9、Sulphur exerts a strong influences on graphite nucleation and its growth , graphitization and graphite morphology .───硫对石墨的形核和生长，对石墨化和石墨形态，有强烈的影响。
