| 摘 要： | 为了使学生更好地理解驻波的能量只在局部区域内流动、没有沿某一固定方向传播这一重要特点,在驻波的能量教学过程中,首先推导出驻波的波腹和波节处媒质质元的能量表达式,再尝试采用图示法定性分析驻波相邻的波腹和波节之间的能量相互转换。图示法具有形象直观、学生易于理解的优点。

| Abstract: | In order to make the students understand clearly the important feature of the standing wave energy , which is only transmitting within a limited area and nonlinear , we first deduce an energy formula for the wave loop and node, then analyze qualitatively by presenting a series of charts to show the energy transition between the wave loop and the node. It provides a really direct and visual illustration for the students. |
