The temperature effcet on mean phonon number of strong-coupling polaron in an asymmetry quantum dot are studied by using an linear combination operator and the unitary transformation methods. The relations of the mean phonon number of polaron with the effective confinement strongth and temperature are taken into consideration. Select-ing RbCl quantum dot, numerical calculations are performed and the results show that the mean phonon number will in-crease with increasing the effective confinement strength and temperature. Selecting different quantum dots, the mean number of phonon is an increasing function of coupling strength and temperature.
