摘要：
A simple mathematical model is proposed to account for emissions of volatile organic compounds (VOC) from homogeneous materials. The model considers multi-emission sources and sinks. An important feature of the model is that all the parameters have clear physical meaning and are confirmed by previous data from experimental chambers or by direct measurement. The model can predict the emission rate of VOC from homogeneous materials into the air. It also can determine the relationship of the emission rates of VOC sources, the bulk air concentration, volumetric flow rate, and the sorption rates of VOC sinks. (C) 2002 Elsevier Science Ltd.
