摘　　要：为研究不同气象参数对多孔建筑材料蒸发过程的影响,实测了4种不同孔隙率的材料在变太阳辐射、温度、相对湿度、风速的4种工况下的蒸发过程。分析了太阳辐射、温度、相对湿度、风速对蒸发过程中的蒸发量和蒸发量变化规律的定量影响,发现太阳辐射对蒸发量以及蒸发量变化规律影响最大,而温度、相对湿度、风速的影响非常小。In order to study the influence of different meteorological parameters on the evaporation process of porous building materials,the evaporation process of four kinds of materials with different porosities under four cases,including solar radiation,temperature,relative humidity and wind speed are studied.The quantitative effects of solar radiation,temperature,relative humidity and wind speed on the evaporation and evaporation variation of evaporation process are analyzed.Solar radiation has the greatest impact on evaporation and evaporation variation is the radiation,while temperature,relative humidity,and wind speed have very little effect.
