材料的吸湿属性。

材料的吸湿属性。IfcMaterial IfcMaterial Upper VaporResistance Factor空气/材料的蒸汽渗透性关系（通常值>1），在高相对湿度（通常为95/50%RH）下测量。较高的蒸汽阻力系数较低的蒸汽阻力系数空气/材料的蒸汽渗透性关系（通常值>1），在较低的相对湿度（通常在0/50%RH）下测量。基于水蒸气密度的低蒸汽阻力系数等温湿容量。等温湿容量蒸气透过率在试验条件下，单位面积每单位蒸汽压差的水蒸气透过率。蒸汽渗透性水分扩散性水分扩散率是一种传输特性，常用于建筑围护结构构件的湿热分析。

Name	Type	Description
UpperVaporResistanceFactor	P_SINGLEVALUE / IfcPositiveRatioMeasure	Upper Vapor Resistance Factor The vapor permeability relationship of air/material (typically value > 1), measured in high relative humidity (typically in 95/50 % RH).
LowerVaporResistanceFactor	P_SINGLEVALUE / IfcPositiveRatioMeasure	Lower Vapor Resistance Factor The vapor permeability relationship of air/material (typically value > 1), measured in low relative humidity (typically in 0/50 % RH).
IsothermalMoistureCapacity	P_SINGLEVALUE / IfcIsothermalMoistureCapacityMeasure	Isothermal Moisture Capacity Based on water vapor density.
VaporPermeability	P_SINGLEVALUE / IfcVaporPermeabilityMeasure	Vapor Permeability The rate of water vapor transmission per unit area per unit of vapor pressure differential under test conditions.
MoistureDiffusivity	P_SINGLEVALUE / IfcMoistureDiffusivityMeasure	Moisture Diffusivity Moisture diffusivity is a transport property that is frequently used in the hygrothermal analysis of building envelope components.
