摘　　要：气候舱法凭借可靠的环境模拟特性和非破坏性,是目前国际与国内广泛采用的实验室检测方法,常用于检测木制品家具、建筑材料和汽车中的有害物质。本研究测定挥发性有机化合物组分的气候舱法回收率,发现持续注射甲苯3h后浓度才达到动态平衡,3h后的平均回收率为87.7%,证明动态平衡法适用于测定气候舱回收率的测定,同时证明了气候舱法测定VOC组分能够符合标准的要求。Due to reliable characteristics of environmental simulation and non destructive, emission test chamber method has been becoming the method to determine harmful substance from cars, building products, wood products and furniture recommended by international standards and national standards. This study used chamber method to measure the recovery of volatile organic compounds The result showed dynamic equilibrium was reached after equilibrium method was proved to be applicable to the by this study： meanwhile, chamber method was confirmed determine volatile organic compounds. 3h and the mean recovery was 87.7%. Dynamic determination of recovery of chamber method to satisfy the requirement of standards to
