| 摘要: |
| 早在五十年代,海洋科技工作者已开始利用浮标布设海洋调查仪器,进行海上观测的试验工作。目前被采用的浮标系统,大体有三种类型:(1)锚泊浮标系统,利用各类自含式海洋调査仪器进行测量,定期收回资料;(2)遥测浮标系统,利用无线电遥控和收发各种海洋观测数据;(3)漂移浮标系统,利用浮标本身的漂移,进行海流和其他要素的观测。本文主要介绍浅海锚泊浮标系统的设计和使用情况。
对锚泊浮标系统的研究和实验,许多国家已做了大量有成效的工作。目前关于浮标的设计和锚泊方法尚无統一意见,但是可以看出,大多趋向于采用水下浮标张缆锚泊。这种方法使得浮标系统比起遥测浮标系统来,较为轻小、经济、方便,适合于进行多站同步观测。国外在海洋调查中经常利用这种系统作较长期的海流观测。
我所在六十年代初就已开始了锚泊浮标系统的研究、实验,1964年进行了新的研究设计工作,并在“全国海洋仪器会战”期间,完成了整套系统的计算设计与海上实验,经过鉴定,建议作小批量生产。
近年来,国家海洋局第一海洋研究所、中国科学院南海海洋研究所利用该浮标系统作过多次海上试用,取得了海流长期观测资料,初步考验了该系统的性能。我们最近又对某些部件作了一定的改进,并进行了海上实验。但是,实验也表明:此方法不宜在渔场区和台风盛行季节使用,因易被渔网拖损和丢失。现综合报告如下。 |

| Abstract: |
| In the first part of this paper, the design method and main technique data about the mooring buoy system are described in detail. This buoy system is generally available for shallow sea where the water depth is no more than 100 meters. It can still function well in weather conditions of force-7 wind, and is not damaged in force-9 wind conditions.
In the second part,information about sea experiment for using the system is related.The mooring buoy system experiment was conducted in Aptil 20th-25th, 1979 and good data on current velocity was obtained by a self-printing current meter, model HLJ1-1, hanging from the buoy by a wire.
Experiments made by throwing and recovering the buoy are also summarized.
Finally, a comment about this buoy system is made after another experiment and suggestions for improving this buoy system are given. |
