中文摘要：
数字模拟基于阶段地方法被开发描述二维的等温的二进制合金的团结。接口形态学的进化被显示出，阶段领域参数的效果为 succinonitrile 丙酮合金被提出。结果显示套住反的水流(ATC ) 能压制许多套住的熔融的包，它被变厚的接口引起。与从 0 ～ 0.05 增加 anisotropy 价值，一粒小圆形的种子成长到第二等的树枝状的、树枝状的尖端速度 monotonically 增加的 develope，并且固体 / 液体的接口的溶质累积清楚地被减少。随联合参数值的增加，而且，接口变得不稳定，方面晶体分叉逐渐地出现并且成长。
英文摘要：
Numerical simulation based on phase field method was developed to describe the solidification of two-dimensional isothermal binary alloys. The evolution of the interface morphology was shown and the effects of phase field parameters were formulated for succinonitrile-acetone alloy. The results indicate that an anti-trapping current（ATC） can suppress many trapped molten packets, which is caused by the thickened interface. With increasing the anisotropy value from 0 to 0.05, a small circular seed grows to develope secondary dendritic, dendritic tip velocity increases monotonically, and the solute accumulation of solid/liquid interface is diminished distinctly. Furthermore, with the increase of the coupling parameter value, the interface becomes unstable and the side branches of crystals appear and grow gradually.
