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 相似文献

The wind waves generated by cold waves are some of the most dangerous waves in Bohai Bay. In this paper records of the wind waves under the influence of cold waves in November, 1968, are discussed. It is shown that the north wind is very strong in spring and winter. The frequency spectrum of the development and decline of wind waves depends mainly on the wind speed. The change of shape and scale parameters of the spectrum are discussed and the calculation equations are shown. 相似文献
