| 1. | The first stage is to split the crude oil into more manageable portions . 第一步就要将原油分割成更易处理的馏分。 |
| 2. | The heavier boiling fractions remain, in liquid form on the manifold wall . 较重的沸腾着的馏分以液态停留在多孔的壁上。 |
| 3. | Light petroleum distillate, generally known as naphtha, was the logical choice . 轻石油馏分,如石脑油是合乎逻辑的选择。 |
| 4. | So the first stage is to split the crude oil into move manageable portions . 因此,第一步就要将原油分割成更易处理的馏分。 |
| 5. | And so the first stage is to split the crude oil into more manageable portion . 因此,第一步就要将原油分解成更易处理的馏分。 |
| 6. | These early observations have been supplemented with results from chemical fractionation . 这些早期的观察曾为化学馏分的结果所增补。 |
| 7. | During the course of the tbp distillation, the distillates which accumulate between specified temperatures are withdrawn . 在真沸点蒸馏过程中,对规定温度范围内所收集的馏分可加以回收。 |
