Summary

A METHOD OF DETERMINING THE THERMAL CONDUCTIVITY OF THE SPECIMEN IS DISCUSSED THEORETICALLY, IN WHICH THE HOT WIRE IS SANDWICHED BETWEEN A PLATE-TYPE SPECIMEN AND A REFERENCE MATERIAL OF KNOWN THERMAL CONDUCTIVITY. IT WAS FOUND THAT WHEN THE THERMAL CONDUCTIVITY OF THE REFERENCE MATERIAL IS KNOWN THE THERMAL CONDUCTIVITY OF THE SPECIMEN CAN BE DETERMINED THEORETICALLY AS IN THE CASE OF APPLYING THE USUAL HOT WIRE METHOD TO A HOMOGENEOUS MATERIAL. THE ERROR AND THE REPRODUCIBILITY OF THE EXPERIMENTAL VALUES ARE WITHIN MORE OR LESS 4% AND MORE OR LESS 1.5% OF THE THERMAL CONDUCTIVITIES OF STANDARD MATERIALS RESPECTIVELY.
