中文摘要：

当室内多种吸附材料共存时，室内挥发性有机化合物（Volatile Organic Compounds，VOCs）浓度的计算相对来讲较为复杂。本文的目的在于找出一种该情况下材料吸附能力的等效简化方法。基于无量纲吸附能力理论分析，本文提出了室内不同吸附材料共存时，以材料无量纲相对质容为简化指标的吸附能力等效面积折算方法。案例模拟与结果分析显示该方法能较好地应用于此类问题，可为室内污染物浓度的简化计算提供参考。

英文摘要：

When muhiple indoor sink materials were coexist,the concentration calculation of indoor volatile organic compounds （VOCs） might be more complicated. In this paper, the purpose was to find out a simplification method. Taking the parameter of material dimensionless mass capacity as the simplified index, the equivalent area conversion method was proposed based on the analysis of dimensionless sorption capacity. The calculation results of the case study indicated that this method was effective for solving this kind of problem.
