摘　　要：通过实验验证了SiO_2气凝胶作为调湿材料的吸/放湿性能及其可重复性,并应用系统辨识方法,对SiO_2气凝胶作为调湿材料应用于建筑围护结构内表面的动态吸/放湿特性进行了初步的辨识研究。并提出了相应的预测模型,预测结果与实验结果吻合较好.In this study, the moisture absorption/desorption capacity and reuse of SiO2-aerogel is validated by experiments. According to the system identification method, the dynamic absorption/desorption characteristics of SiO2-aerogel which is supposed to be building surface material is forecast. In addition, the forecasting model is established. The result of model calculation is close to that of the experiment.
