成核

It can be presumed that the nucleation rate of HHM will increase with the rise of temperature and supersaturated ratio, when toluene used as dissolvent.

What determines a particle's potential for nucleation is its "critical supersaturation".

粒子的"临界过饱和"决定了它的成核潜力。

The supersaturation used is too low to produce an appreciable rate of nucleation.

所用的过饱和度太低，不能产生一个值得重视的成核率。

The results indicate that, comparing with the crystallization without urea, the time of crystal occurrence is 1.5 times longer, the density of suspensoid is raised by 50%, both of crystal length and crystal width are increased, especially...

粒度分布的定量分析显示，尿素硫酸摩尔比为 3.6：1、过程温度80℃时，硫酸钙的成核速率减少了25%，但结晶成长速率增加了1.2倍，结晶粒度分布中心由72.8mm 增大到 142.8mm，平均粒径由70.98mm 增加为 105.45mm 。

In addition, the addition of additives such as sodium potassium tartrate could not only increase effectively the transmembrane flux and improve the quality of crystals, which lead to shorter induction time period and larger crystals in size.

另外，添加剂酒石酸钾钠的加入不仅可以有效提高溶剂跨膜通量，改善晶体质量，促进晶体成核及生长，得到质量更完美的晶体。

The effects of flame retardant agent and toughener on the property of the prepared engineering plastics were studied.

工程塑料用PET结晶性能的改善大都是通过添加成核剂、增塑剂等助剂来实现，但由于添加剂价格昂贵，且依赖进口，成为制约其大规模应用的一个瓶径。

Results show that the incorporation of tremolite has the function of heterogeneous nucleation to nylon 1010 crystallization. With the increase in tremolite, the crystallization rate of nylon 1010 is enhanced and the Avrami exponent n is slightly decreased.

结果表明：透闪石对尼龙1010结晶起到了异相成核的作用，尼龙1010的结晶速率随透闪石的含量的增加而提高，Avrami指数n略有降低。

For researching the kinetics of unseeded batch crystallization process, the KNO3-H2O system was tested and the assumption that the kinetic characteristic after spontaneous nucleation is similar to that of seeded crystallization process was proposed.

以KNO3-H2O为模型体系，考察了未添加晶种的间歇结晶过程动力学，将历经爆发成核后的结晶体系近似为添加晶种的结晶体系。

Substitutional impurities have changed the local density distribution of adatom and vacancy, which will somewhat influence nucleation and further change the growth model and the atomistic state of the film.

替位杂质改变了表面吸附原子与空位缺陷的区域分布及密度分布，这将一定程度的影响表面原子的成核，进而改变薄膜的生长模式以及薄膜的微观状态。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
