摘要
本文就杨氏模量在机械纵波中的波速、任意体积内的势能和动能及在两种介质界面处入射波、反射波、透射波的振动周相关系中的作用作了阐述。
The effects of Young's modulus on the wave velocity ,on the potential energy and kinetic energy in arbitrarily volume in the maocinery longitudinal and on the vibration phase among incidance ware, reflex wave and transmission wave at the boundary surface of two kinds of medium are discusseed.
