初探WKB近似法中波函数的选择

Brief Study on the Choice of the Wave Fmction in WRB Approximation

本文分析了教科书中利用WKB近似法求解势垒贯穿几率时选择波函数的方法,讨论了该方法的局限性.并通过对典型问题的处理,说明了在利用此近似法处理量子力学问题时,正确选取波函数的基本准则.

This paper analyzes a method of choosing wave function when making use of WKB approximation to deal with the transmitted probability of potential barrier in the textbooks and points out some of the defects in this method Then the paper also explains a base rue for the correct choice of the wave function when making use of WKB approximation to deal with the problem of quantum mechanics
