摘　　要：比较了测定人造板甲醛释放量的几种方法,认为气候箱法测定值较易换算成直观的居室空气质量值。提出人造板甲醛释放分游离甲醛及结合甲醛2种来源,其释放速率受2种机理控制。解释了气候箱法及日、美干燥器法为什么要在试样于一定环境下放置7天后才读取数据的原因。分析了推广气候箱法必须具备的条件。为保护居民健康,提出加大执法力度的建议。By comparing several test methods of formaldehyde emission, it is considered that data from chamber test is easier to be converted into indoor air quality value which has visual nature. It is suggested that formaldehyde emission comes from two sources, free formaldehyde and bound formaldehyde, and their emission rates are controlled by two different mechanisms. It is explained why for chamber test, as well as for desiccator test in America and Japan, the data should be adopted after the specimens have been laid under certain circumstances for 7 days. The necessary conditions for generalization of chamber test is discussed. For protecting people＇s health, a proposal of strengthening the law enforcement is suggested.
