摘　　要：认识金属中氢与位错之间的交互作用是理解氢脆微观机制的关键。本文介绍了氢促进局部塑性变形理论(HELP)的提出、内涵与研究进展,并进行述评。针对HELP机制的主要现存问题,给出了一种氢与位错交互作用研究的新范式,并作出展望。The key of understanding hydrogen embrittlement mechanism of metals is to fully elucidate the interaction between hydrogen and dislocation.This paper introduces the history,content and development of the theory of hydrogen enhanced localized plasticity(HELP)and reviews it critically.The unsettling questions regard HELP mechanism are emphasized and addressed.In order to answer the unsettling questions,a new research methodology to reveal the interaction between hydrogen and dislocation is presented and prospected.

关 键 词：氢脆 机理 氢促进局部塑性变形
