室内材料和物品中气态有害物散发特性测定方法评述
Review on measurement methods of pollutant emission characteristics from indoor materials and products
摘要：
室内材料和物品散发的气态有害物（主要是挥发性有机化合物VOC）是造成室内空气质量低劣的主要原因之一，并可能对人体健康、室内舒适性和工作效率产生长期的影响。室内环境中VOC的源散发和控制研究已成为当前传热传质学和建筑环境科学交叉领域的研究热点。对室内材料和物品（主要为建材和家具）散发特性的测定方法进行了评述，这些方法对表征材料散发过程本质规律的三个关键参数——初始可散发浓度、扩散系数和分配系数进行测定，重点介绍了具有代表性的直流舱C-history方法。
Abstract：
The gaseous pollutant (mainly volatile organic compound, VOC) emitted from indoor materials and products is one of the main cause for poor indoor air quality, which would significantly affect people’s health, comfort and productivity. Study on the emission and control of VOC from indoor materials has therefore become a hot interdisciplinary topic in the fields of heat and mass transfer and building environment science. Reviews the existing methods for measuring the pollutant emission characteristics of indoor materials and products (mainly building materials and furniture). These methods focus on determining three emission characteristic parameters, i.e., the initial emittable concentration, the diffusion coefficient and the partition coefficient. Emphasizes a typical method—the ventilated chamber C-history method.
