| 摘 要： | 本文从理论上分析了温度和相对湿度对气溶胶质量浓度分布的影响。即，温度影响空气对流和气溶胶粒子的布朗运动，进而影响气溶胶的垂直分布，使其质量浓度的改变满足负指数规律变化；相对湿度与气溶胶质量浓度是正相关的关系。根据分析，提出了一个气溶胶质量浓度温湿度修正反演模型，并通过实验数据对模型进行验证，实验结果表明该模型能很好的反映温湿度对气溶胶质量浓度分布的影响。

| Abstract: | The influence of the temperature and relative humidity upon aerosol mass concentrations distributions has been discussed. The temperature affects the particles’ Brown movement and air convection, and the vertical changes of mass concentration meets the negative exponent law. The relative humidity affects water-soluble particle’s absorbtion of moisture, and is linear with the aerosol mass concentration. A model for retrieving aerosol mass concentration with temperature and humidity correction is developed and confirmed by experimental data. The result indicates that the model reflects the influence of the temperature and relative humidity to aerosol mass concentrations distributions. |
