【摘要】 用自行设计的 RDL-1型物质热导率自动检测仪测试了真空橡胶板、石棉板等材料在不同温度下的热导率 ;由测试数据分别建立了这些材料的热导率随温度变化的一元线性回归方程 ,并对其有效程度及线性相关显著性进行了评价 .结果表明 ,大多数绝热材料在其实用温度范围内 ,热导率随其实验的冷热面平均温度变化关系都适应于文中所建立的线性回归方程 .更多还原

【Abstract】 The thermal conductivity of heat insulation materials,containing vacuum rubber board, asbestos board and quartz glass etc.was tested at different average temperature with RDL 1 automatic measuring apparatus made by ourselves.Their linear regression equations were respectively built both at cold side and heat side on the basis of the data measured above.It was proved that the form of linear regression of the each material is sole and believable.更多还原
