heterogeneous nucleation

基本解釋

Stirring of substrates may accelerate the heterogeneous nucleation and growth of the melt.
襯底的攪拌可加速熔體的非自發(fā)成核和長大。
Continuous nucleation model was used to describe heterogeneous nucleation of the liquid metal.
在模擬過程中，采用連續(xù)形核的方法處理液態(tài)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—晶體生長過程形成的，晶體生長在孔隙中和喉道處均可發(fā)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,得到了外加核心為與混合氣體中重組分互溶、不發(fā)生化學反應且揮發(fā)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(xù)形核模型被用來處理異質形核現象,在生長模型中則考慮了枝晶尖端生長動力學和擇優(yōu)生長方向。
