摘要
随着石油工业的发展,油已成为海洋上最主要的污染物之一。我们于1986年7月30日、31日,8月2日、5日,1987年5月24日两次在胶州湾进行了六次实验(分别称实验1,2,3,4,5,6),基本上掌握了油在海面上的稀释扩散规律,为防止油对海洋的污染,预报污染区域和范围,提供了可靠的数据。
Experiments show that the diameter of oil film increases with time, but its weight (thickness) decreases with time, presenting an opposite trend of change. Igt correlates with IgC and IgR linearly. However, the speeds of changes differ from each other under hyodrologic, meteorological, topographical conditions and amount of different oil. The oil film diffuses rapidly if direction of the wind is the same as direction of current. The oil film diffuses slowly if direction of the wind is opposite to current. The smaller the molecular, weight of oil. the rapider the diffusion of oil film. The amount of oil and the thick of oil film do not present direct proportion simply. The meteorological condition of experiment 2 is the most conservative in the six experiment, The diffusion coefficiency of the petroleum in Jiao-zhou Bay is calculated as 0.464m2/s according to data of experiment 2. The core of oil film is thickest, it gets thiner with the increase of distance from core, the oil film presents normal distribution.
