This paper discusses the method using silver film concentration pipe to measure the gaseous mercury in the atmosphere,the elements that influence the absorption rate of gaseous mercury,and the ways of regenerating silver film concentration pipes. The results show that the silver film concentration pipe can effectively concentrate the gasesous mercury in the atmosphere. The absorption rate can reach 98% when the length and diameter of the pipe is bigger than 200mm/4.5mm and the flow is 0. 4L/min.%探讨了用银膜富集管测定大气中气态汞的方法、影响气态汞吸收率的因素和银膜富集管的再生方法。结果表明：银膜富集管对大气中的气态汞能有效富集。当银膜长／管径大于200mm／4．5mm，流速为0．4L／min时，银膜富集管对气态汞的吸收率达98％以上。
