WKB近似中基函数选择方式

Methods of choosing basic function in WKB approximation

WKB近似法的应用非常广泛,计算势垒贯穿几率是其应用之一.为了简化计算、明确图像,运用连接公式,讨论了WKB近似方法中选择基函数的两种方式,并对它们进行了比较,提出了基函数的选择标准.

WKB approximation method has various utilisations including the calculation of potential barrier transmitter probability. In order to simplify the calculation, clear the images, and utilise connection formula, two methods of choosing the base functions in WKB approximation are discussed and compared in this article. The standard of choosing the base function has also been brought forward.
