本文通过分析光学材料中光谱与温度之间的关系证实了晶体生长过程中的相变团簇模型,认为晶体内部热辐射流是引起固-液界边界层温度场发生传导的可能原因。引入了前结晶的概念,并结合实际中的不同晶体生长方法讨论了包裹体及气泡的抑止机理,通过计算得到了生长理想晶体的最大生长速率并且解释了由于界面层的摆动使得晶体生长过程中产生的微气泡没有被移动的界面层所捕获。
In this paper, the phase transition cluster model in the process of crystal growth is confirmed by analyzing the relation between the spectra and the temperature in the optical material. It is considered that the thermal radiation inside the crystal is the possible reason for the conduction of the temperature field in the boundary layer of the solid-liquid boundary. The concept of pre-crystallization was introduced, and the suppression mechanism of inclusions and bubbles was discussed in combination with the actual different crystal growth methods. The maximum growth rate of the ideal growth crystal was calculated and explained that the growth of the crystal growth process The resulting microbubbles are not captured by the moving interface layer.
