介绍了一种低温热膨胀系数测量仪。利用热膨胀仪测定了酚醛泡沫塑料在77-293 K温度范围内的热膨胀系数。结果表明，酚醛泡沫塑料的热膨胀系数在测试温度范围内很低，误差约为± 7.3%。(C)2003 Elsevier Ltd.保留所有权利。
A dilatometer measuring thermal expansion coefficient at low temperatures is introduced. The thermal expansion coefficient of phenolic foam, a widely used thermal insulation material, was measured in the temperature range of 77-293 K by the dilatometer. The results showed that the thermal expansion coefficient of phenolic foam was very low in the tested temperature range with an error of about +/-7.3%. (C) 2003 Elsevier Ltd. All rights reserved.
