摘　　要：采用改进的线性组合算符和幺正变换分别导出强、弱耦合情况下束缚磁极化子的振动频率和光学平均声子数,并以RbCl晶体和AgCl晶体为例进行了计算.结果表明束缚磁极化子的振动频率λ随磁场B的增加而增加,光学声子平均数N随耦合常数α的增加而增加.In this paper,by using linear combination operator and unitary transformation method,we have calculated respectively the vibration frequency,the mean number of optical phonons of the strong and weak-coupling bound magnetopolaron.Numberical calculations for the RbCl and AgCl crystal,as an example,are performed and some properties of the vibration frequency λ,the mean number of optical phonons N of the bound magnetopolaron are discussed.The numerical results show that the vibration frequency λ increases with increasing of the magnetic field B,the mean number of optical phonons N of the bound magnetopolaron increases with the increasing of coupling constant α.
