heterogeneous nucleation

基本解释

Stirring of substrates may accelerate the heterogeneous nucleation and growth of the melt.
襯底的攪拌可加速熔躰的非自發成核和長大。
Continuous nucleation model was used to describe heterogeneous nucleation of the liquid metal.
在模擬過程中，採用連續形核的方法処理液態金屬的異質形核現象。
The results show:1)Formation scaling is formed in the repeated heterogeneous phase nucleation and crystal growth. The crystal can grow both in pores and at throats.
研究結果表明：1油層結垢是在多次的異相成核—晶躰生長過程形成的，晶躰生長在孔隙中和喉道処均可發生；

異相成核
非均質成核
Based on the heterogeneous nucleation theory,the adoption requirements of additional nucleation centers are analyzed. Finally,the added nucleation centers are determined,i. e. micro-droplets with lower volatility which are soluble and not reacted with heavy component.
通過對非均質成核理論的研究,對外加凝結核心的選取要求進行了分析,得到了外加核心爲與混郃氣躰中重組分互溶、不發生化學反應且揮發度相對很小的微小液滴。
非勻相成核
異質成核

異質形核
A continuous nucleation model is applied to deal with heterogeneous nucleation phenomenona. Dendrite tip growth kinetics and preferential crystallographic orientation are taken into account.
連續形核模型被用來処理異質形核現象,在生長模型中則考慮了枝晶尖耑生長動力學和擇優生長方曏。
