摘　　要：针对定向凝固模拟的研究现状,概述了其中几种用于凝固的模拟方法,如三维枝晶胞膜跟踪法、电磁成形法、相场法等,并着重介绍了相场法。最后,在分析现有相场模型不足的基础上,指出了该领域研究中亟需解决的问题,并对今后的发展方向作了分析。The state-of-art of the simulation of directional solidification was given in order to describe its several methods, such as 3D dendrite envelope tracking, electromagnetic shaping and the phase-field method, etc; the phase-field method had been introduced mainly; additionally, the existing problems and the development directions in the future had been pointed out. Finally, the problems needed to be resolved urgently over the simulation of phase-field as well as the trends were proposed based on analyzing the disadvantages of the phase-field models available.
