| 摘 要： | 在研究了海水中石油烃自然风化模式的基础上，以实验室模拟，研究了原油和燃料油自然风化速率的差异以及微生物含量对风化速率的影响，结果表明，原油的自然风化速率稍低于燃料油，尽管微生物含量增加使其对石油烃降解的绝对量明显增加，但对烃类被降解的百分率以及风化速率常数基本上没有影响。由于微生物的含量本身就是海水中石油烃含量的函数，因此石油烃的风化速率仅为油含量的函数，而与微生物的含量无关。

| Abstract: | Difference in natural weathering rates of crude oil and fuel oil and effectof weathering rate by microbiological levels were studied in laboratory based on the complet-ed natural weathering model of petroleum hydrocarbons in seawater.The results showedthat the weathering rate of crude oil was lower than that of fuel oil.The percent of hydro-carbon degrated and the constant of weathering rate were not affected by the hydrocarbon-degrating bacterial levels in seawater although the degrated quantities of hydrocarbon wereincreased with rises of microbiological level.The weathering rate of petroleum hydrocarbonswas only a function of the oil concentrations in seawater,and independent of microbiologicallevels,because the hydrocarbon-degrating bacterial levels were actually a function of the oilconcentration in seawater. |
