水下压力式波浪计是测量近海海浪常用的一种仪器。长期以来,人们认为这种仪器是获得海面波浪资料的一种可靠设备。不少国家先后制成了不同原理的水下压力式波浪计,观测到很多有价值的资料。对海浪研究和近岸工程起了一定的作用。然而,为了得到海面波浪,需要知道水下压力波和海面波浪的换算关系。尽管早就由流体力学方法就线性波理论导出了这
Underwater pressure wave gauge is a commonly used instrument for measuring offshore waves. For a long time, people think this kind of instrument is a kind of reliable equipment for obtaining sea wave data. Many countries have made submarine pressure wave gauges with different principles one after another, observing a lot of valuable information. It has played a role in ocean wave research and offshore engineering. However, in order to get the sea wave, it is necessary to know the relationship between the underwater pressure wave and the sea wave. Although this has long been derived by the fluid mechanics approach of linear wave theory
