| 摘要: |
| 当今通信技术的发展和应用已渗透到人类社会的各个领域，对社会发展产生巨大影响。在海洋领域，通信技术经历多次重大跨越，从最原始的旗语到现在的卫星移动通信，海陆之间的联系已经变得较为便利。但目前我国海陆即时通信技术还不够完善，给科考船的深远海作业带来诸多不便，轻则影响作业进度，重则造成巨额经济损失甚至人员伤亡。在卫星电话、电子邮件等通信方式存在信号不稳定、直观性差、即时性低等弊端的情况下，研究和开发较为成熟的海陆即时通信技术极为必要。文章探讨科考船在海上作业期间与陆地进行即时通信的方法和可行性，为今后这项技术的发展提供参考。 |

| Abstract: |
| Nowadays the Development and Application of communication technology has permeated in nearly every aspect of human society，and has had a strong impact on social development.In the oceanographic field，communication technology has undergone a momentous leap，from the primitive flag signals to the current satellite mobile communication，which has facilitated the connection between land and sea.However，sealand real time communication technology is not perfect enough in China，which has brought much inconvenience to deep sea survey，ranging from working process delayed to economical loss and even casualty.With the drawbacks such as unstable signal，low intuition and poor real time property，it is very necessary to research and develop more advanced landsea real time communication technology.This paper discussed the method and feasibility of realtime communication between oceanographic vessel and land，and provided reference for future development of this technology. |
