弯曲波和横波的区别

有没有知道,弯曲波(flexural wave)和横波(transverse wave )的区别。这两者是怎样产生的。
在绳子的端部上下抖动得到是哪一种波。谢谢!

横波是指扰动中质元的运动方向和扰动的传播方向垂直的波,在绳子的端部上下抖动得到的是横波。至于弯曲波还是第一次听说

Transverse Waves(横波) In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. The animation below shows a one-dimensional transverse plane wave propagating from left to right. The particles do not move along with the wave; they simply oscillate up and down about their individual equilibrium positions as the wave passes by. Pick a single particle and watch its motion. http://www.kettering.edu/~drussell/Demos/waves/Twave.gif

弯曲波我也不太懂,还请高人指点啊。
