| 摘 要： | 在铁质船体周围进行海流观测,在没有外部罗经输入的情况下需要由仪器内部磁罗经确定海流方向,必然会受到船体磁场的影响。利用多组实测数据比较了由于船体影响产生的流向偏差,分析了偏差产生的原因以及可能的解决办法。

| Abstract: | Iron hull＇ s magnetic field would influence current observation when there was no exterior magnetic compass. This paper compared the flow-direction deviation caused by hull, based on many measured data. Then the paper analyzed the reason of the deviation, and the possible solution of the deviation. |

| Keywords: | current observation magnetic compass data analysis |
