摘　　要：分析金卤灯外封杂质气的来源及危害,探讨以锆基合金为主的非蒸散型吸气剂(Non-Evaporable Getter,NEG)的发展及特性,描述几种典型的NEG在金卤灯中的应用,列出其激活条件、工作温度、吸氢速率等。此外,还介绍了在特殊条件下,如氮气环境中、高温时,NEG在金卤灯中的应用。This paper analyzes the source and damage of gas impurities in metal halide lamp shells, explores the development and characteristics of non-evaporable getters（NEGs） and their application in metal halide lamps. Several classic NEGs used in metal halide lamps are described and its activation condition, operating temperature and hydrogen absorption rate are listed. Besides, the application of NEG in metal halide lamps under some special conditions is introduced, such as nitrogen atmosphere and high temperature.
