摘要
本文通过理论分析和实验研究,得出了多孔状绝热材料导热系数随温度变化的规律,给出了准确确定其导热系数随温度变化经验公式的方法.并提出可用复相关系数和剩余标准差控制实验及经验公式的精度.
On the basis of the theory and the analysis of the experimental results,the law of mermal conductivity coefficients is obtained of multihole heat insulation materials with temperatur changing,the method is provided by which the empirical formula of the thermal conductivity coefficients of multihole heat insulation materials is accurately determinated,and the way of controlling the experimentation and the precision of empirical formula is also provided with the multiple correlation coefficient and residual standard deviation.
