热学计量中,除温度之外,还应包括燃烧热、溶解热、比热容、热传导和热膨胀的测定。本文主要介绍热容、热传导和热膨胀的计量。材料的热容、热传导和热膨胀是材料科学中生气勃勃的一个分支。近十年来,有关各种材料的热容、热传导和热膨胀的研究有了很大的发展,很多国家的计量机构也大力开展在不同温度范围(包括低温和高温)内的热容、热传导和热膨胀的研究。
Thermometry, in addition to temperature, should also include the combustion heat, heat of dissolution, specific heat, heat conduction and thermal expansion of the determination. This article focuses on heat capacity, heat conduction and thermal expansion of the measurement. Material heat capacity, heat conduction and thermal expansion are a branch of the dynamic science of materials. In recent ten years, great progress has been made in the study of heat capacity, heat conduction and thermal expansion of various materials. Many countries’ metrology institutes also vigorously carry out heat capacity, heat conduction and thermal expansion in different temperature ranges (including low temperature and high temperature) Research.
