摘要：

A method of indirectly measuring the heat emissivity for alloys is presented in this paper. Electromagnetic levitation and an infrared thermometer are used in this method to calculate the heat emissivity for alloys according to this principle that the electromagnetic levitation force is equivalent to the gravity force in levitation state, and the absorbed power is equivalent to the dissipated power in thermal equilibrium state for a smple. The heat emissivity of 0.524 for (TbDy)Fe-2 alloys at 1455 degreesC is obtained by using this method.
