In order to determine the computational parameters in the sea ice numericalmodel considering the ice characteristics of Bohai Sea, the author devoted to thefield ice survey in the past 7 winters, and a great lot valuable data was obtained.

• 为使渤海海冰的数学模型能够适应渤海冰情特点，并对其中的重要计算参数进行确定，作者在辽东湾JZ20-2海域进行了连续7个冬季的海冰现场观测，完成了多次破冰船海冰和沿岸冰的调查工作，获得了大量的海冰观测资料。
