摘要: 本文回顾了晶体生长理论研究的发展历史,对现有理论的局限性作了评述,认为现有理论的局限性主要表现为:对于环境相结构效应和生长条件变化的忽视;用平衡态热力学和统计物理学解释非平衡态的晶体生长过程;对于浓厚相和多元晶体生长体系缺乏理论模型.并对今后的发展方向提出了看法.

关键词: 晶体生长理论, 研究现状, 局限性

Abstract: The development of the theories of crystal growth was reviewed and the limitations of present theories were discussed. These limitations
were summed up as: ignorance of the structures of the circumstance phase, ignorance of the growth conditions, the employment of thermodynamics and
statistical physics of equilibrium state to explain non-equilibrium process of crystal growth, and lack of theoretical model on the growth mechanism about
high density circumstance and multi-element crystal system. Moreover, the lately development of the theories and resarch methods about crystal growth was also introduced. Finally, some
opinions about the directions of future development were proposed.

Key words: theories of crystal growth, research situation, limitations
