中文摘要：

综述了共晶生长理论模型的发展，介绍了JH、TMK、KT、LZ和含少量第三组元的过冷共晶生长理论模型在阐述凝固行为、组织形成机制方面的作用。现有的过冷共晶理论模型有一定的局限性，主要表现为非平衡态下溶质截留对晶体生长过程的影响缺乏考虑。

英文摘要：

The progress in the theoretical models of eutectic growth is reviewed. The roles of theoretical models （JH, TMK, KT, LZ, etc. ） in solidification behavior and formation mechanism of microstructure are introduced. The existing eutectic models have their limitations,mainly in the lack of considerations on the effect of solute trapping on the growth process.
