【Abstract】 This paper decusses the necessary condition under which the phonons conduct the heat in a fractal medium and deduces the frequency band of the specific heat capacity at constant volume in this kind of medium. The results show that the specific heat capacity at constant volume in a fractal medium is always less than that in a homogenous medium.更多还原
