%X The properties of the effective mass of polaron in semiconductor quantum dot are studied.The relations between the vibration frequency,the interaction energy and the effective mass of the polaron at the electron-LO phonon strong coupling in parabolic quantum dot with the confinement strength and the electron-phonon coupling strength are derived by using an improved liner combination operator method.Numerical calculations for RbCl crystal are performed and the results show that the vibration frequency and the effective mass will increase with the confinement strength increasing.Whereas the interaction energy is harshly increased until the confinement strength reaches a certain value,then it will sharply decrease.
