摘要
开发出一种使用热线法测量和确定高温下固体材料导热系数的新方法。本文介绍了测量温度可达到１５００℃的实验设备、应用“热四极子法”建立的数学模型、基于参数估计方法的参数识别技术以及一些陶瓷材料导热系数新的实验结果。
A new measurement technique for thermal conductivity of solids at high temperature by the hot wire method is developed.The following points are presented:experimental setup for measurement up to 1500℃,model construction by the 'thermal quadrupole method', identification technique based on a parameter estimation method and new experimental results for ceramic materials.
