摘　　要：为提高抑尘车喷雾在大气环境中的降尘效率,选取大气污染程度、环境相对湿度及喷雾时长为试验因素,以PM;20min沉降率、40 min沉降率及60 min沉降率为评价指标开展完全析因试验。试验结果表明:大气污染程度和环境相对湿度对评价指标的主效应最强,且有些因素之间的二阶交互效应和三阶交互效应超过了喷雾时长的主效应。In order to improve the dust suppression efficiency of the dust suppression truck in the atmospheric environment,the air pollution level,environmental relative humidity and spray time are selected as the test factors,and the complete factorial experiments are carried out with PM;sedimentation rates of 20 min,40 min and 60 min as evaluation indexes.The experiment results show that the main effect of air pollution level and environmental relative humidity on the evaluation indexes is the strongest,and the second-order interaction effect and the third-order interaction effect between some factors exceed the main effect of spray duration.
