By approaching variations of physical and chemical properties (i.e.,rates of vapour and dissolution,surface tension,coefficient of viscosity and density) of spilled oils during weathering from application of grey system theory,GM(1,1) and GM(0,m) of forecasting models of the physical and chemical properties of spilled oils during weathering are established.The results show that: (1) the precision and accuracy of the forecasting of GM(1,1) and GM(0,m) with statistical test are satisfactory,(2) the grey relativities of the physical and chemical properties of spilled oils during weathering can be expressed as the parameters of grey recognition of GM(0,m) and (3) The surface tension,the coefficient of viscosity and the density can be taken as the factors of forecasting of the rates of vapour and dissolution of spilled oils during weathering.
