| Abstract: | n this paper, it is discussed to determine the thermal coefficients,such as thermal conductivity, specific thermal capacity and so on, by nonstable state method and quasi--stable state method in plane heat source. In order to simplify the calculation and to improve the accuracy, it is proposed to improve the main instruments and the method for measurement and calculation. In addition, the merits and defects of two methods are compared. Their respective appropriate measure conditions and ranges are also proposed. |
