Thought the pan evaporation , it has been found that the evaporation of shengli crude oil is controlled by the first step and the effect of wind velocity is small . the prediction equation is dw / dt ^ k d ? 2 a ju , y hct / t , which is related with the liquid characters and states ( e . g . thickness , area , viscosity ) and is independent of wind speed
2 、实验结果表明，胜利原油蒸发由第一步即蒸发由液体内部易挥发组分向液体表面的迁移来控制，因此风速影响很小，建立速率方程时不必考虑风速，只需考虑液体本身的性质和状态(如厚度、表面积、粘度等) ，速率方程可写为： dw dt = kd4 ? ’ a严t 。
