本研究的目的是为了预测室内颗粒物浓度的几个墙壁纹理的沉积常数的实验测定。实验包括将球形颗粒（直径为0.7、1.0和5.0 μm）注入一个立方体盒子中，盒子的内表面被待测纹理覆盖。通过对浓度指数衰减曲线的回归拟合，确定了沉积的全局常数。从Crump和Seinfeld理论（J. Aerosol Sci. 12（5）（1981）405）。这种分解方法已被测试为5.0 μm，然后被扩展到更小的颗粒。
The aim of this study is the experimental determination of deposition constants for several wall textures in order to predict indoor particles concentration. Experiments involved the injection of spherical particles (0.7, 1.0 and 5.0 μm in diameter) in a cubic box whose internal faces are covered by the texture to be tested. Global constants of deposition are determined by regression fitting of the concentration exponential decay curves. Deposition constants are deduced for each orientation from the Crump and Seinfeld theory (J. Aerosol Sci. 12(5) (1981) 405). This decomposition method has been tested for 5.0 μm and then been extended to smaller particles.
