理论上研究了非对称Gaussian限制势CsI量子阱中强耦合极化子的性质，采用线性组合算符和LLP变换方法导出了非对称Gaussian限制势量子阱中强耦合极化子的振动频率和平均声子数与非对称Gaussian受限势量子阱的势垒高度和非对称Gaussian受限势的范围的关系。通过数值计算，结果表明极化子振动频率和声子平均数是Gaussian受限势的范围的减函数，而它们是量子阱的势垒高度的增函数。

The properties of strong-coupling polaron in an asymmetrical Gaussian confinement potential CsI quan-tum well are theoretically studied. The relations of the polaron’s vibrational frequency and the mean number of pho-nons on the barrier height of the quantum well and the range of the Gaussian confinement potential are derived by us-ing the linear combination operator and LLP transformation methods. The numerical results indicated that the polar-on’s vibrational frequency and the mean number of phonons are a decreasing function of the range of the Gaussian confinement potential, whereas they are an increasing one of the barrier height of the quantum well.
