摘　　要：高热阻端头型管状绝热材料测定装置戴锅生（东南大学动力工程系，南京２１００１８）目前国内外通常使用的防护端头型管状绝热材料测定装置测量准确，但它有３个加热器和３套带有调节器的电源。测量前主测试段和防护端头间的隔缝温差必须被控制到接近于零［１～３］，且结...In order to improve the measurement of the thermal conductivity of the insulation, the thermal resistance of the two ends of the test pipe for the so called “idtaltype”aplraratus is increased.As a result, the accuracy of the measurement can meet the demands of the relative sbedards in China and abroad. The construc tion of the improved apparatus is simpler than the conventional pipe insula-tion test apparatus with guarded ends. It is also convenient to use and easy to sprea
