| and then perfected during the 1940s | 并于1940年代发展成熟 |
| to detect submarines lurking in the deep. | 已经能够用于探测深海藏匿的潜艇 |

| The waves bounce off solid | 声波遇固体目标反射 |
| objects and are reflected back to a detector. | 继而返回至探测器 |
| By measuring the time it | 通过测量声波返回所需的时间 |
| takes for the sound waves to bounce back, | 科学家意识到 |

| picture of the world beneath the waves. | 水下世界图像 |
| The world's major navies spend a lot of time | 全球主要海军均投入大量时间与精力 |
| and effort developing submarine hunting technology, | 开发潜艇搜寻技术 |
