中文摘要：
当溢油事件发生在有冰覆盖海域时,海面油膜的各项特性的变化规律将发生显著变化。针对这一问题,采用室内试验的方法对渤海可能发生的冰期溢油事件进行了模拟,重点针对溢油在有冰覆盖海面上的特性变化进行了详细观测,并依据观测数据对相关变化规律进行了探讨。试验中分别对轻质原油和重质原油试样进行了测试,并针对渤海常年遇冰条件进行了模拟。试验内容包括：油膜厚度、油膜蒸发率以及乳化黏度在不同冰块覆盖率下随时间的变化情况。试验测试结果表明,溢油的各项风化进程均将受到海冰的影响。
英文摘要：
When oil spills occur in ice-covered sea areas, the varying regularity of the properties of surface oil film will have significant changes. To tackle this problem, experiments were performed to simulate possible oil spilling events in the ice-covered period of the Bohai Sea. The variations of oil spill properties were carefully observed and measured, and discussions were carried out on the relative varying regularity based on the observing data. Light and heavy crude oil samples were respectively tested in the experiments, with simulation targeted for the usual ice condition in the Bohai Sea. The experiments include measuring the oil spill thickness, evaporative loss rate and the emulsion viscosity that changes with time under different ice coverage. The testing results indicate that the weathering processes of oil spills are influenced by the presence of sea ice.
