当填充因子为偶数时，其本征能量的绝对值最大，此时电子气对库仑势的屏蔽效应最弱。
The electron gas screening on Coulomb potential can be weakened greatly when Landau level filling factor is an even number.
结果表明，束缚极化子的振动频率和有效质量随库仑势的绝对值的增加而增大。
The results show that the vibration frequency and effective mass of the strong - and weak - coupling bound polaron will increase with increasing the absolute value of the Coulomb potential.
