石油和汽油的蒸发损耗大概是石油工业损耗的最重要的原因之一,因此,千万疏忽不得,这些损耗迷惑人的特征是由于常常在通常温度下百分之几的原油体积的变化导致相当大的原油膨胀系数。这个物理特性与量测、计量和取大量液体样的误差一起常常反而助长掩盖了所出现的那些可观的蒸发。当长期观察时,这些损耗的量变成很明显。 The evaporation loss of petroleum and gasoline is probably one of the most important causes of oil industry losses and, therefore, should not be neglected. These loss-deceiving characteristics are due to changes in the volume of crude oil, which is often a few percent of the normal temperature Large crude oil expansion coefficient. This physical property, often in conjunction with measurements, metrology and taking large amounts of liquid-like errors, instead helps to mask the considerable evaporation that has occurred. The amount of these losses becomes significant when observed over time.
