摘　　要：溢油海面的"Marangoni"效应是指油膜对短重力波和毛细波具有一定的抑制作用,它是SAR区分溢油与清洁海面的物理基础。本文采用Fung&Lee海浪谱和Lombardiniet溢油模型,定量分析了归一化溢油因子对波高斜率均方根的影响;根据海浪的Longuet-Higgins模型,仿真了溢油海面和清洁海面的波高样本,验证了油膜对短重力波和毛细波具有一定的抑制作用。Marangoni effect of the sea surface with oil slicks means the damping in the shortgravity wave and capillary wave region, which is the physical basis of SAR detecting oil slicks. In this paper, the Fung ＆ Lee spectrum and Lombardiniet model of oil slicks are presented. The effect of RMS of sea surface height slope is quantitatively analyzed by normalized oil factor F. According the Longuet-Higgins ocean wave model, the wave heights of the sea surface with and without oil are simulated. The damping effect by oil slicks is verified in the short-gravity wave and capillary wave region.
