摘要：

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 mum 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 mum and then been extended to smaller particles. (C) 2001 Elsevier Science Ltd. All rights reserved.
