Abstract:In order to realize the accuracy of the thermal property of thin sheet materials. Based on the basic
principle of parallel hot wire technique, temperature measuring points are arranged at direction of thickness of the
specimen instead of the original direction which is arranged parallel to hotline, and consider the impact of heat pene鄄
tration effect. The directly measured coefficient of thermal conductivity and thermal diffusivity using numerical method
combined with computer programming material. The intelligent test system about thermal properties is developed. The
objects of the thermal property test experiment are glass, asbestos, diatomite refractory brick, and so on. The results
agree well with national standard test method for test values and literature values. Considering the impact of heat pene鄄
tration effect, it can also accurately achieve thermo鄄physical properties of thin solid plate by controlling the effective
testing time, need not melt sample, through which the application range of the hot wire method is effectively expand鄄
ed.
