摘要
临界现象的研究进展缓慢 ,6 0年代实验方面的发展使人们相继建立了几个标度理论及普适性理论 ,并提出了标度变换概念 .威耳逊一直从事量子场论的研究 ,对相变理论也很关注 ,对这些唯象理论不满 .他把量子场论中的重正化群概念应用到相变理论中 ,并运用标度律和普适性概念 ,建立了临界点的重正化群理论 ,提供了研究临界点现象的系统方法 .
The study of critical phenomena has progressed slowly. Experiments in 1960s led to the formulation of scaling laws and universality. While K.G.Wilson was studying quantum field theory, he was also interested in phase transitions but he was not satisfied with these representative theories so he applied renormalization group concepts of quantum field theory to phase transitions. In addition to implementing the concepts of scaling laws and universality, he developed a renormalization group theory for critical phenomena, which is the only systematic approach in this field.
