| 4. | The rate of evaporation depends on the material and such factors as the temperature , the surface area , amount of ventilation , and the pressure exerted on the surface 蒸发速率取决于材料及诸如温度、蒸发面积、通风量和施加在此蒸发面上的压力等因素。 |
| 5. | According to the feature of oils , the evaporation of crude oils is not controlled by the boundary layer and the prediction equation based on the water evaporation equation is not correct theoretically 结合原油组分特点,认为过去将原油蒸发当边界层控制来处理,以及以纯水蒸发速率方程为基础通过修正而建立起的原油蒸发速率方程是缺乏理论根据的。 |

| 7. | On the basis of analysis for experimental data , the relationship of power between evaporation mass and time for naphtha was found and the average value of the power is about 0 . 70 原油的蒸发几乎不受风速、液池面积的影响,这说明原油的蒸发受边界层条件控制的程度很小,其蒸发速率主要由其自身性质(如分子扩散系数、蒸气压等)所决定,其蒸发过程是受基本蒸发过程控制的。 |
| 8. | More meaningful comparisons can be made by comparing water loss from the potometer with that from an atmometer ( an apparatus used to measure the rate of evaporation from a porous pot or other nonliving wet surface ) , which allows uncontrolled evaporation 更有意义的是,可以比较蒸腾计的失水与蒸发计(通过有孔小罐或者潮湿表面来测量蒸发速率的仪器)的失水间的区别。 |
