摘　　要：测定保温材料导热系数的自补偿圆管法⒇王素美宗祥康施明恒（东南大学动力工程系，南京２１００１８）测定工程保温材料，特别是管形保温材料导热性能，一般采用圆管法［１］．圆管法的基本原理是通过圆筒壁的一维稳态导热［１，２］．被测试材做成圆管状，置于圆管导热装...A cylinder method for measuring the thermal conductivity of thermo insulating materials with heating of self compensation is proposed. Analysis shows that the single scheme of compensating heating is appropriate in the range of thermal conductivities 0 04-0 10 W/m·K .
