摘　　要：瞬态平面热源法是一种快速测试材料导热系数的方法。国内外大量学者对测试设备、测试方法及原理等进行了广泛研究,为自保温砌块导热系数的快速检测和判定提供了新的思路,但在运用中发现,含水率、尺寸、厚度及平整度均会在不同程度上影响瞬态平面热源法检测导热系数。基于此,文章通过正交试验设计,并用单因素方差分析各组导热系数,以期在检测结果可靠的前提下缩短检测时间,提高检测效率,为相关工作者提供参考依据和技术支持。Transient plane source method is a rapid method to test the thermal conductivity of materials.A large number of scholars at home and abroad have carried out extensive research on test equipment,test methods and principles,which provides new ideas for the rapid detection and determination of thermal conductivity of self-insulation blocks.However,it is found in application that moisture content,size,thickness and flatness will affect the detection of thermal conductivity by transient plane source method to varying degrees.Based on this,this paper uses orthogonal test design and one-way analysis of variance to analyze the thermal conductivity of each group,in order to shorten the detection time and improve the detection efficiency under the premise of reliable detection results,providing reference and technical support for relevant workers.
