我们看到一些水泡从水下升起。 |
| 2. | We saw bubbles rising from under the water
我们看到一个个水泡从水下升起。 |
| 3. | When water boils , bubbles rise to the surface
当水煮开时，气泡浮上表面。 |
| 4. | I saw bubbles rising from under the water
我看见一个个水泡从水下升起。 |
| 5. | The light , fragile bubbles rise to a fine , smooth foam
轻盈的汽泡上升后形成圆润，柔滑的泡沫。 |
| 6. | This process continues while the bubble rises , and the bubble grows bigger and bigger
这个过程在气泡上升的途中会不断发生，所以气泡会不断变大。 |
| 7. | Larks sprang up trilling one after another in the fields , like bubbles rising to the surface of water
云雀唱着嘹亮的歌，像泉水的泡珠似的一个接一个，扑棱棱地从田野里腾空而起。 |
| 8. | A bubble rises because its density is less than that of the soft drink . this buoyancy increases as the bubble grows archimedes principle
由于气泡的密度比周围的汽水低，气泡会上升，而浮力会随著气泡变大而增加阿基米德定律。 |
| 9. | When a bubble rises , it will experience less pressure in the surrounding liquid and therefore become larger . however , the change of pressure is very small in view of the short path from the bottom of the glass to the liquid surface . therefore , pressure change is not the major cause of bubble growth
虽然气泡在玻璃杯中上升时，周围的水压会逐渐减少，令气泡膨胀，但由于从玻璃杯底至水面的距离其实很短，水压的变化不是太大，所以这不是气泡变大的主要原因。 |
