数值模拟需要准确和精确的热物理性质，以便开发改进的高温工艺，例如半导体材料的晶体生长和发动机和涡轮机叶片的铸造。微重力环境是材料科学的工具之一，为测量提供了明显的优势;主要的好处是没有对流和保证无容器处理。本文不仅回顾了过去进行的涉及热物理性质测量的微重力实验，而且回顾了利用最初为空间实验开发的技术在地球上测量热物理性质的努力。热物性测量是空间工作引发的材料科学新领域之一。展望了空间站时代，特别强调了机遇和挑战。
Accurate and precise thermophysical properties are required for numerical modelling, so that improved high temperature processes can be developed such as crystal growth of semiconductor materials and casting of engines and turbine blades. The microgravity environment, one of the tools of materials sciences, offers marked advantages for the measurements; the major benefits are the absence of convection and the assurance of containerless processing. This paper reviews not only past microgravity experiments dealing with thermophysical property measurements but also the efforts to measure thermophysical properties on Earth using techniques developed originally for space experiments. Thermophysical property measurement is one of the new fields of materials sciences triggered by working in space. An outlook into the space station era is also given with special emphasis on opportunities and challenges.
