摘　　要：平面简谐波是理工科专业《大学物理》课程中的重要内容。势能的分析和推导是平面简谐波教学中的难点。本文利用弹性波的传播机理和特征,提出一种简易的分析和推导平面简谐波势能密度函数的方法。此方法可以避开学生陌生和难以理解的一些物理量和概念,因此其可使教学过程大为简化,并便于学生掌握和深刻理解相关内容。Simple harmonic plane-wave is an important content of 〈〈College Physics〉〉 course which is a required course for the students of science and engineering specialties. It may he not easy for students to deeply understand the potential energy during the study of the simple harmonic plane-wave. This paper proposes a very simple method of analyzing and deriving the potential energy, by using the transmission mechanism and characteristics of the elastic wave. This method does not involve the physical quantities that are unfamiliar to students, and thus can simplify the teaching process and benefit the students in understanding the related contents.
