摘　　要：运用DOE全因子实验设计方法,研究了Na^+、Mg^(2+)、Cl^-和K^+等4种常见可溶盐离子在高湿环境下对脱硫石膏板下垂变形的影响,并利用DOE实验分析方法对其影响的显著性进行研究。结果表明:高湿环境下K^+、Mg^(2+)和Na^+均为脱硫石膏板下垂变形的显著因素,其中Mg^(2+)和Na^+会大幅增加其下垂挠度,而K^+对含盐脱硫石膏板下垂变形则有明显的抑制作用,具体表现在K^+明显降低脱硫石膏板因添加Na^+、Mg^(2+)可溶盐离子所引起的下垂变形。This thesis adopts full factorial design of the DOE（design of experiment） to explore the effects of four soluble salt ions （Na＋,Mg2＋,Cl- and K＋） on the deformation of desulfurized gypsum board in high moisture environment,and the effect of each ion was analyzed by DOE analysis method. The results indicate that K＋,Mg2＋ and Na＋ are significant factors affecting the sagging deformation of the desulfurized gypsum board in high moisture environment,in which Mg2＋ and Na＋ ions greatly will increase their sagging deflection,while K＋ has the obvious inhibitory action on the deformation of desulfurized gypsum board,which is represented in reducing the sagging deformation of desulfurized gypsum board caused by adding of Na＋ and Mg2＋ ions.
