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.
Experimental results show that based on the ridge of the wave and Curvelet watermarking algorithm has some theoretical and practical value.
实验结果表明本文的基于脊波和曲波的水印算法具有一定理论和实用价值。

The antenna element has a ridge element unit (21) for adjusting antenna characteristic corresponding to a ridge portion and a radial element unit (22) for electromagnetic wave radiation.
