摘　　要：利用72个渤海石油平台、站点测流资料,阐明了渤海的平均余环流特征,并用已有的数值计算结果阐明了其形成机制。观测表明在黄河三角洲近海存在一支北-东北向的流动,可抵达秦皇岛附近水域,数值计算表明该支流动主要是潮生的;在辽东湾北部存在一顺时针向的涡旋运动,在冬半年该涡旋是风生的;在渤海湾北部存在潮生的逆时针向的余环流。With the current data measured from 72 oil platforms, the mean residual circulations are explained in the Bohai Sea. It was shown that in the offshore area of the Yellow River delta there is a north-northeasward current, which reaches the offshore area off Qinhuangdao. This current is in fact a tidal residual current. In the northern part of Liaodongwan Bay a clockwise eddy exists, which may be induced by wind in wintertime. In the northern part of Bohai Bay an anticlockwise circulation exists, which is also a tidal residual current.
