Abstract: The influences of electric field and temperature on properties of strong-coupling bound megnetpolaron in parabolic quantum wires are studied by using of the linear combination operator and the unitary transformation methods. The relations of the ground state energy, the mean number of megnetphonon and the vibrational frequency in parabolic quantum wires with the confinement strength, the cyclotron resonance frequency and electric field were calculated. The numerical results show that the ground state energy will increase with the confinement strength, the cyclotron resonance frequency and electric field, however, it will decrease with increasing of the temperature and the coupling strength. The mean number of phonon is a increasing function of the temperature and the confinement strength and the cyclotron resonance frequency. The variation frequency will increase with increasing of the cyclotron resonance frequency and the confinement strength.
