摘　　要：通过研究水、乙醇和卡托辛在HTPB和PEG-TPU 2种材料中的渗透汽化通量,分析了这一参量和组分扩散特性之间的关系,并对其作为组分迁移特性表征方法的可能性进行了探讨。初步研究表明,不同组分在HTPB-1衬层中的渗透通量各不相同,渗透通量依次为乙醇>水>卡托辛,但渗透通量都随测试温度的提高而增加。水在PEG-TPU中的渗透通量远大于HTPB中的渗透通量,据此可为衬层材料的选择提供一定参考。The relationship of the permeation flux and component diffusion property was analyzed on the basis of the permeation flux of water, ethanol and catocene through HTPB and PEG-TPU membranes. The possibility as a characterization method for component migration was discussed. The preliminary results show that the permeation flux of different component is different for HTPB-1 liner. The permeation flux increase in the following sequence ： ethanol 〉 water 〉 catocene, and it increases along with the temperature increases. The permeation flux of water in PEG-TPU is superior greatly to that in HTPB, and the method might be used for the selection of liner materials.
