摘　　要：溢油不仅污染了海面,并伴随着水流的流动污染了海底沉淀。利用直接法和间接法同时测量溢油污染物的声速,通过声速平均差值判断溢油的位置及浸没深度,从而跟踪溢油的动态。根据外场试验总结得出溢油的特征及扩散情况:在海流和风流的作用下溢油不断扩散,随着溢油浓度的降低,声速降低,在相对窄的大陆架内溢油存留在10m的水层内,并扩展到更深的区域。Oil spill not only pollute the sea,but also pollute the bottom sediment with the flow of the water.The direct method and indirect method are used together to measure the velocity of medium,through velocity difference to judge the location of oil spill and the depth of immersion to track the dynamic state of oil spill for post-processing.According to the field experiments,the feature and difference of the oil spill is summarized： oil spill continuously diffused under the role of current and air flow,with the decreasing concentrations of oil spill,the speed of sound reduced,oil was stranded in the water 10 m layer and extended to deeper areas.
