一、引言我国海域辽阔,漫长的海岸线长达一万八千多公里.在这辽阔的海洋中,存在着各种各样的波动,蕴藏着丰富的能量资源,而这种能源取之不尽,用之不竭.象高频波动的海浪,潮频的潮位和潮流,它们的能量有的已经被利用,有的正在被利用.而在海洋中还存在一系列其它波动,如低频水位的波动,它仍含有自己的能量,这也有待于我们去研究.本文用能量谱分析的方法给出该海区低频水位能量的分布并分析能量的来源.因为“谱”系指能量相对于各组成波的频率的分布,水位具有的能量是由各组成波动贡献而得.所以谱是于整个频率范围内实行积分的结果,是水位变化总能量的量度.而
I. INTRODUCTION The vast and long coastline of our country has a total length of over 18,000 kilometers. In this vast sea, there are various fluctuations and abundant energy resources, which are inexhaustible. , Inexhaustible.As waves of high-frequency waves, tides and currents of tidal frequency, some of their energy has been used, and some are being used.And there are a series of other fluctuations in the ocean, such as low-frequency water level It still needs its own energy, which is yet to be studied by us.In this paper, we give the energy distribution of the low-frequency water level in the sea area by energy spectrum analysis and analyze the source of energy because “spectrum” The distribution of the frequency of each component wave, the energy that the water level has, is contributed by the component fluctuations, so the spectrum is the result of integrating over the entire frequency range and is a measure of the total energy of the water level change.
