  1. 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 、實驗結果表明,勝利原蒸發由第一步即蒸發由液內部易揮發組分向液表面遷移來控制,因此風速影響很小,建立速率方程時不必考慮風速,只需考慮液本身性質和狀態(如厚、表面等) ,速率方程可寫為: dw dt = kd4 ? 』 a嚴t 。
  2.
