【摘要】 本文通过对驻波中能量密度和能量密度变化率的推导得出在驻波中不断进行着动能和势能之间相互转换和在波腹与波节间的转移，而其总机械能守恒。但没有能量的定向传播，故驻波并不是能量传播过程。更多还原

【Abstract】 It is deduced in the paper that kinetic euergy and potentiad euergy are converted andtrausfered between a wave crest and wave node in a standing wave. The author’s analysis ofenergy density and it vary ratis reveals that the energy is consered but not transported in onedirection. The conclusion is that the energy is not transfered in a standing wave.更多还原
