球坐标系中导出轨道角动量算符表示式的简单方法

A simple method to introduce the expression of orbital angular momen- turn operators in spherical co--ordinates

轨道角动量算子Ｌ是很重要的力学量算符，求解Ｌ２和ＬＺ的本征值方程必须导出Ｌ＾２和ＬＺ在球坐标系中的表达式。本文介绍一种推导这两个算符在球坐标中表示式的简单方法。

The orbital angular momentum operators L are very important mechanical operators. To solve the eigen equation of L2 and LZ,we must introduce the expression of L2 and LZ in spherical co ordinates.Here, we give. a simp method to introducelthe expression.of L2 and LZ in spherical co ordinates.
