The mountain wave induced by a ridge in two-layer stratifiedfliud has been successfully simulated in a tank . The wave pattern is almost the same compared with the linear theory result qualitatively.

利用不同密度分层的盐水模拟稳定层结大气条件，在水槽中成功地模拟了两层大气分层流中二维山脊引起的地形波，得到的波动图像与线性理论模式结果在定性上基本一致。

From a distance high mountain scenery, only saw the hill like a wave of ten percent.

远远望去高高的山脉时隐时现的，只看见小丘似的一波一折的。

This gesture represented an early ripple before a wave of modernity was allowed to sweep through his secretive mountain kingdom, a world all of its own between China and the northeastern tip of India.
