利用原子簇团跳跃理论模型，建立了动态结晶条件下的晶体生长速度微观动力学模型，指出古典连续生长（ＣｏｎｔｉｎｕｏｕｓＧｒｏｗｔｈ或ＣＧ）模型仅是本模型的一个特例．理论分析结果表明，晶体的生长速度除与金属本身性质有关外，还与过冷度△Ｔ、外力Ｆ有关．利用此模型分析了流体流动条件下柱状晶、柱状枝晶的某些结晶现象． Using the theory of cluster jumping theory, a microcosmic dynamic model of crystal growth rate under dynamic crystallization was established. It is pointed out that Continuous Growth (CG) model is only a special case of this model. Theoretical analysis shows that the growth rate of the crystal is related to the nature of the metal itself and to the degree of supercooling △ T and the external force F. Some crystal phenomena of columnar and columnar dendrites under fluid flow were analyzed by using this model.
