提出了一种新的变分解的方法求解极化子问题,并归结为解一个非线性的微分积分方程。其数值计算的结果正是过去工作所预期的。A new variational method for solving polaron problem is suggested, and the nonlinear differential-integral equation satisfied by variational solution of plolaron has been derived, the numerical result of which is as anticipated by earlier. works.
