人们对于海洋表面的波都很熟悉,当这些波的波长大于1.7cm时被称作为重力波,因为重力(不是表面张力)提供了使它们得以形成的基本的恢复力.类似的波若是发生在两层不同密度且下重上轻的流体界面上,就不为人所熟悉了.如果在一不可
People are familiar with waves on the surface of the ocean and are called gravity waves when their wavelength is greater than 1.7 cm because gravity (not surface tension) provides the basic restoring force that allows them to form. Two different density and light weight on the lower fluid interface, it is not familiar .If you can not
