摘要
采用自洽平均值近似法求解三维非线性谐振子的能量本征值,并与其精确解和微扰论结果相比较,结果表明,自洽平均值近似法求得的能量本征值不仅引入的误差较小,且计算过程也得到了简化。
The three-dimensional nonlinear oscillator energy eigenvalue is obtained by using the average selfconsistent approximation method. It shows that compared with the results obtained by the exact solution the results are more errorless and the perturbation theory, the calculation by using the self-consistent approximation is simpler and than that by using the perturbation method in treating these models.
