【摘要】 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．更多还原

【Abstract】 A new experimental method for measurement of the thermal conductivity of material at solid and liquid phases near the melting/freezing point has been designed.The thermal conductivity of pure metal,alloy,organism as well as the packed bed composed of distilled water and sodium glass which have been obtained by this method at low temperature phase point are good agreement with datas from the literatures as well as from the mathematical simulation.The results prove the method on research heat conduction and thermophysical property at phase transition point is feasible.更多还原
