| 摘要: |
| 海洋波浪能是一种可持续和零污染的再生能源，随着自然能源日渐匮乏和全球气候变化，人类对波浪能的开发利用显得尤其重要。本文应用"跨零-能量"波浪分析的新方法，首次推导了不规则波浪的波能流垂向分布及其理论计算公式。本文研究发现，浅水波能流具有均匀的垂向分布，深水波能流集中于海表层的水体中，过渡区波能流的垂向分布介于浅水和深水波能的分布之间。研究还发现，目前海洋波能流的估算方法和现今波浪发电装置的波能采集深度缺少相关性，过高估算了海洋波浪的可发电资源。 |

| Abstract: |
| Wave energy is continuous, nil-pollution and renewable. With continuous consumption of traditional natural energy resources and global warming in the world, it becomes increasingly important to make use of renewable wave energy. This study has applied a new wave analysis method "zero crossing-energy balance" to derive the vertical distribution of ocean wave energy flux and also theoretical formulas valid for both intermediate and deep water depths. It is found in this study that wave energy flux is uniformly distributed in shallow water, concentrates near the sea surface in deep water, and lies between the distributions in the shallow and deep waters. This study also found that the amount of ocean wave energy flux estimated presently is much less than that absorbed by wave power generation devices. |
