【Abstract】 Based on an analysis of the main factors affecting the transmission depth of the heat radiative wave in film materials, a correlation between the transmission depth with the film thickness was obtained. Theoretical analysis indicate that when the thickness of the film materials is equivalent to the average free path of the electron, the transmission depth of the heat radiative wave can be increased effectively by reducing the film material thickness so that the heat radiative characteristics of the film material can be improved significantly.更多还原
