THE LAW OF DILUTION AND DIFFUSION OF PETROLEUM AND ITS PRODUCTS ON THE SEA SURFACE

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.
