【Abstract】 -A physical and mathematical model of the One-Wire Cutout Method (OWCM) is set up for measuring thermal conductivity of materials. The testing techniques and factors influencing precision of measurement are discussed and analysed. The thermal eonduetivities of several material are measured and satisfying results are obtained, that OWCM could be a reliable, simple and rapid measuring method.
