运用改进的线性组合算符与变分相结合的方法,研究无限深量子阱中强耦合束缚极化子的性质.得到束缚极化子的基态能量和库仑束缚势、阱宽以及拉格朗日乘子的关系.通过数值计算结果表明：当库仑束缚势、阱宽和拉格朗日乘子增大时,基态能量的绝对值增大.%The properties of the strong- coupling bound polaron in an infinite quantum well are studied by using variational method and the improved linear - combination - operator. The variational relation of the ground - state energy E0 of the bound polaron with the coulomb bound potential β, the electron- LO phonon coupling strength or, the well - width d and Lagrange multiplier u is derived. The results of numerical calculation show that the ground- state energy E0 will decrease with increasing the electron- LO phonon coupling strength or, the Coulomb bound potential/3, the well -width d and Lagrange multiplier u.
