:气态介质对建筑材料的腐蚀性分级决定于介质类型、浓度及环境湿度。一般情况下 ,介质类型可预先确定 ,而介质浓度与环境湿度是相互耦联的。本文针对“一刀切”分级方法在边界附近的不合理现象 ,运用模糊数学方法建立了具有部分耦联因素的气态介质腐蚀性的模糊分级 ,并建议了多种介质共同存在交叉影响时 ,多介质综合腐蚀性的模糊合成方法。
: The classification of the corrosivity of gaseous materials on building materials is determined by the type of medium, the concentration, and the ambient humidity. Under normal circumstances, the media type can be predetermined, and the media concentration and ambient humidity are coupled to each other. This paper aims at the irrational phenomenon of the “one size fits all” grading method near the boundary. Fuzzy mathematics method is used to establish the fuzzy classification of the corrosiveness of gaseous medium with some coupling factors, and it is suggested that when multiple media coexist in the cross-impact, multi-media synthesis Corrosive fuzzy synthesis method.
