驻波
一种全部能量都被限制在特定边界之内并被其反射的波。这种波具有一个或多个相对于上述边界位置固定的波节。驻波由两列振幅相等、沿相反方向传播的行波组成。
驻波不会向负载输送任何能量。对于在空气中振动的谐振器(与谐振器内部储存的能量相比,向空气传递的能量可以忽略),谐振器内部的波本质上就是驻波。
Standing wave
A wave in which all of the energy is trapped within and reflected by specified boundaries. Such waves will have one or more nodes that are fixed, relative to the specified boundaries. A standing wave will consist of equal traveling waves that are moving in opposite directions.
A standing wave does not deliver any energy to a load. For a resonator that vibrates in air (where the energy transfer to the air can be neglected compared to the internal energy storage of the resonator), the waves within the resonator are essentially standing waves.
