| Abstract: | The principle of thermal conductivity measurement which based on pulse plane heat source method was analyzed. By using the pulse plane heat source method, thermal conductivity of insulation coating was measured at room temperature. Origin7.0 software was utilized for curve fitting instead of looking up a data in table of the formula ierfe （λ）, and the expression of iterative curve fitting was input in Excel to carry out data processing and computing. The calculation error is avoided and the efficiency and accuracy of the calculation are improved. Thermal conductivity,thermal diffusivity and specific heat are gotten fast and accurately. |
