摘　　要：通过各国学者数十年的不懈努力,现已建立了比较完善的规则共晶凝固理论模型,人们对共晶间距的选择机制及其形态转变有了较深刻的理解。有关非规则共晶凝固理论的研究工作虽有许多,但这些模型仍极不完善。本文中,在综合评述规则共晶凝固理论研究的基础上,着重阐述了近年来非规则共晶凝固理论的研究进展,提出了非规则共晶凝固理论研究的发展方向。The regular eutectic solidification theory has been established after the great efforts of several years＇ research from the solidification scientists all over the world. This relatively mature theory has revealed the selection mechanism of regular eutectic spacing and has demonstrated the evolution process of regular eutectic morphplogy. However, although the irregular eutectic solidification theory has also been widely studied, the corresponding models remain unconvincing and incomplete to a large extent. In this paper, the eutectic solidification theory is thoroughly reviewed while the emphasis is the important achievements on the irregular eutectic solidification theory in recent years. Afterwards the further research direction of irregular eutectic solidification theory is put forward.
