heterogeneous nucleation

基本解释

Stirring of substrates may accelerate the heterogeneous nucleation and growth of the melt.
衬底的搅拌可加速熔体的非自发成核和长大。
Continuous nucleation model was used to describe heterogeneous nucleation of the liquid metal.
在模拟过程中，采用连续形核的方法处理液态金属的异质形核现象。
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.
研究结果表明：1油层结垢是在多次的异相成核—晶体生长过程形成的，晶体生长在孔隙中和喉道处均可发生；

异相成核
非均质成核
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.
通过对非均质成核理论的研究,对外加凝结核心的选取要求进行了分析,得到了外加核心为与混合气体中重组分互溶、不发生化学反应且挥发度相对很小的微小液滴。
非匀相成核
异质成核

异质形核
A continuous nucleation model is applied to deal with heterogeneous nucleation phenomenona. Dendrite tip growth kinetics and preferential crystallographic orientation are taken into account.
连续形核模型被用来处理异质形核现象,在生长模型中则考虑了枝晶尖端生长动力学和择优生长方向。
