摘　　要：以苯胺为研究对象,用自制的环境测试舱模拟室内环境,分析了苯胺在环境中释放和衰减的特性,以及相对湿度和初始苯胺质量对苯胺释放过程的影响.结果表明,苯胺释放特征曲线呈一阶指数函数递增,苯胺衰减特征曲线呈一阶指数函数递减;相对湿度和初始苯胺质量对苯胺释放过程有重要影响,降低相对湿度能提高苯胺初始释放速率,且该影响在苯胺释放初期更为明显;初始投加的苯胺质量越高,气相中苯胺的浓度(质量浓度ρ,全文同)越高.The self-made environmental test chamber was used to study the release and attenuation characteristics of aniline, effects of relative humidity and the amount of initial aniline on emission process were analyzed. The experimental results show that the release characteristic curve of aniline is fitting an increasing first-order exponential function. The attenuation characteristic curve of aniline is fitting a decreasing first-order exponential function. Both of the relative humidity and the amount of initial aniline have significant effects on emission process. Reducing the relative humidity can improve the initial aniline release rate and this effect is more obvious at the preliminary stage. The higher the amount of initial aniline, the higher the concentration of aniline in gas phase.
