摘　　要：基于液氢高效存储、运输和利用对低温高效绝热的需求,以真空多层材料为主要研究内容,总结了液氢温区真空多层材料的绝热性能测试数据。根据液氢温区的获得方法将多层材料绝热性能的测试方法分为基于低温液体蒸发的湿式量热法和基于制冷机的干式量热法两种,并从结构形状、温控方式、量热方式和测量范围等方面综述了这两种方法的研究现状,对比分析了各自的优缺点。最后展望了多层绝热材料的主要研究方向。Based on the requirement of high-efficiency insulation at low-temperatures for efficient storage,transportation and utilization of liquid hydrogen,the testing data of vacuum multilayer materials at liquid hydrogen temperatures were summarizes.According to the method of obtaining the temperature of liquid hydrogen,the test methods of insulation performance of multilayer materials were divided into two categories:calorimetry using cryogenic liquid and cryogen-free calorimetry using cryocoolers.The state-of-the-art of these two methods was compared and reviewed from the aspects of structure shape,temperature control mode,calorimetry mode and measurement range,and their advantages and disadvantages were analyzed.The main research topics of multilayer insulation materials in recent years were summarized.
