| 英文摘要 | The emulsi?cation of crude oil is caused by the oil ?owing into the water, resulting in the increase of oil ?lm tension, viscosity, water content, and volume, which brings great harm to the marine ecological environment and difficulties for the cleanup of marine emergency equipment. The realization observation of emulsi?cation crude oil will increase the response speed of marine emergency response. Therefore, we set up crude oil emulsi?cation samples to study the physical property in laboratory and conducted radar measurements at dif ferent incidence angles in outdoor. The radar is C band in resolution of 0.7 m by 0.7 m. A fully polarimetric scatterometer(HH, VV, and VH/HV) is mounted at 1.66 m(minimum altitude) height at an incidence angle between 35° and 60°. An asphalt content of less than 3% crude oil and the ?ltered seawater were used to the outdoor emulsi?cation scattering experiment. The measurement results are as follows. The water content can be used to describe the process of emulsi?cation and it is easy to measure. Wind speed, asphalt content, seawater temperature, and photo-oxidation af fect the emulsifying process of crude oil, and af fects the normalized radar cross section(NRCS) of oil ?lm but wind is not the dominant factor. It is the ?rst time to ?nd that the emulsi?cation of crude oil results in an increase of NRCS. |
