设计了一种测试物质相变点固、液相导热系数的新方法．采用该方法测试处于低相变温度下的纯金属、合金、有机物和湿多孔材料相变时固、液相的导热系数，结果与文献数据或数值计算数据吻合较好．研究表明该方法用于研究物质相变温度下的热传导，以及相变点的热物性是可行的． A new method to test the phase change point solid and liquid phase thermal conductivity of the material was designed. This method was used to test the thermal conductivity of solid and liquid phases of pure metals, alloys, organic materials and wet porous materials under low transformation temperatures. The results agree well with the literature or numerical data. Studies have shown that this method is feasible for studying the heat conduction at the phase transition temperature and the thermophysical properties of the phase transition point.
