用WKB法的近似解作为精确解求微分方程

Using the Approximate Solution of WKB Method as an Accurate One to Solve a Differential Equation

用ＷＫＢ近似方法解薛定谔方程，得到的解是近似的．本文提出一种用该近似解作为精确解求微分方程的方法，求得该微分方程可以分析解的近似条件及解的近似程度等问题．

The solution is an approximate one when WKB method is used to solve the Sehrodinger Equation. This paper introduces a method of using the approximate solution as an accurate one to solve a differential equation. Based on the differential equation solved, it is possible to analyse such problems as the approximate terms and degrees of the solution.
