عوامل مهم موثر بر مقاومت حرارتی و نفوذ حرارتی اتاق بخار

We also developed a device for the measurement of thermal diffusivity based on the Angstrom method. We then measured (under experimental conditions) the thermal diffusivity of four pure metals for comparison with standard reference values. The thermal diffusivity values were measured as follows: VC (44.04 cm2/s) and copper plate (1.219 cm2/s).
