摘　　要：该文结合超导无磁杜瓦的研究，测定了某些低温玻璃钢等非全属材料的热膨胀系数，得出了玻璃钢等多层复合材料的线膨胀系数是各向异性的，不同组分的玻璃钢其膨胀系数各不相同，尼龙的线膨胀系数一般大于玻璃钢材料等结果，为工程应用提供了有价值的数据．Associating with the study of super conucting non-magectism dewar bottle,the themal ecxparsion rate of some glass-fibre reforced plastic etc. cryogenical materials were presented:teh linear expansion rates of these mutilayer composites are directional properties,the expansion rate of glass-fibre reforced plastic of different ingredients in different;the linear expansin rate of nylon is greater thant that of glass-fibre inforced plastic etc.materials.Valuable data are presented wich can be useful to engineering application.
