浩瀚无边的海洋,面积达3.61×10~8km~2, 约占地球表面的71%,汇集了地球97%的水量,蕴藏着丰富的能源.由于海洋能可再生的总量相当可观,海洋能的利用带来的环境污染小, 所以世界各国正竞相探索海洋能的开发和利用技术. 1.潮汐能因月球引力的变化引起潮汐现象,潮汐导致海水平面周期性地升降.因海水涨落及潮水流动所产生的能量,称为潮汐能.我国海岸线曲折漫长,蕴藏着十分丰富的潮汐能资源.其中浙江、福建两省蕴藏量最大.约占全国的80.9%.
The boundless ocean covers an area of 3.61×10~8km 2 , accounting for 71% of the earth’s surface. It brings together 97% of the earth’s water and contains abundant energy. Since the total amount of renewable marine energy is considerable, ocean energy The use of environmental pollution caused by the use of small, so the countries around the world are competing to explore the development and utilization of ocean energy technology. 1. Tide can cause changes in the lunar gravity caused by tidal phenomenon, tides cause the sea level to periodically lift. Because of seawater fluctuations and The energy generated by the tidal flow is called tidal energy. The coastline of our country is long and winding, and it is rich in tidal energy resources. Zhejiang and Fujian provinces have the largest reserves, accounting for 80.9% of the country.
