摘　　要：近些年来,许多学者都在研究晶体花样如何形成及其生长速度的理论,由于控制这一动力学过程的数学模型的复杂性使得定量研究这一自然现象非常困难,本文建立了描述这一过程的拟稳数学模型,得出与前人相同的结果。并对晶体存在拟稳生长解进行分析从而有助于从本质上认识这一现象。In recent years, many scholars have examined how crystal pattern formation and growth rate theory, as a result of controlling the dynamics of the complex mathematical model makes quantitative study of the natural phenomenon is very difficult, this paper , based on the results of the formers, established a quasi - stable mathematical model of this processes, analyzing the conditions of the growth solutions and having the same results as the formers, thus helping understand this typical phenomenon intrinsically.
