The main results are as follows : 1 ) it is a obvious effect of wave on the wind drag coefficient . the wind drag coefficient can be add up to 1 . 5 times of origin value when we consider the wave effect on the drag coefficient . it also has changed the sea level 主要成果如下: 1 、波浪对表面拖曳系数的影响是明显的,特别是在浪大的时候,拖曳系数可以增大到原来的1 . 5倍;拖曳系数的改变也改变了水位场,在a点引起的增水量级值得人们注意。
