摘　　要：针对灰色理论只能预测等时间间隔的系统发展变化规律这一不足,构建了改进的灰色GM(1,1)模型,以聚甲基丙烯酸甲酯(PMMA)/蒙脱土纳米复合材料在硫酸溶液、氢氧化钠溶液和蒸馏水中的吸水率预测为例,研究所建模型在PMMA及其复合材料吸水率预测中的适用性。结果表明,所建模型在三种介质中的吸水率的预测精度等级均为1级,模拟值与实际值的相对误差最大为10.11%,可用于PMMA及其复合材料吸水率的预测。Referring to the shortcoming that GM （1,1） model can only predict system development and change at intervals of equal time, improved GM （1,1） model was constructed according to Grey Theory. Regarding water absorption rate prediction of PMMA/MMT nanocomposites under 0.1 mol/L H2SO4 solution, 0.1 mol/L NaOH solution and deionized water respectively as an example, applicability of the constructed model in water absorption rate prediction of PMMA and its composites was researched. The results show that the prediction accuracy grades of the constructed model in three mediums are all one, the maximum relative error between simulation value and actual value is 10.11%, and the constructed model can be used to predict water absorption rate of PMMA and its composites.
