　　The amplitude damping factor and detention period, in the unsteady-state heat transfer of building envelope, are analyzed, with the method of periodic heat transfer theory, on the base of determining continuous functions for outdoor air temperature and solar radiation equivalent air temperature.On the premise of indoor air temperature constant, the temperature function of building envelope's inner surface is obtained hy the synthesis of different waves, which is the foundation for constructing unsteady-state heat transfer equation in building envelope with dual-wave import.Compared with other unsteady-state heat transfer calculations, this method reflects more periodic waves' characteristics.
