| 1. | Nucleation sites facilitate the growth of bubbles
成核位置有助气泡形成。 |
| 2. | Both water droplets and bubbles require nucleation sites to form
水滴和气泡均需要成核位置才可形成。 |
| 3. | Study of active nucleation site density in subcooled nucleate pool boiling
池内过冷核沸腾表面活化核心密度的研究 |
| 4. | These spots are often pitted and cracked , and have many sites , called nucleation sites , where bubbles easily grow
它们通常会是一些凹坑或裂缝，分布于多个位置称为成核位置，气泡容易形成。 |
| 5. | After a bubble is released from its nucleation site , it grows as it makes its way to the surface [ see middle illustration at left ]
当一个气泡从成核点释放出来后，它会一边奔向表面，一边不断成长（参见上页中图） 。 |
| 6. | The investigation results show that fly ash particles serve as nucleation sites for the growth of the hydration products and the quality of fly ash does not affects the microstructure of concrete much
研究结果表明：粉煤灰颗粒充当水化物的中心质，掺加粉煤灰使混凝土层状形貌得以改善，孔隙下降，不同品质粉煤灰对早期水化物的生成有明显的影响。 |
| 7. | It is interesting to note that , besides the small cracks in the glass and the impurities inside the drink , the bubble itself in its ascent also acts as a nucleation site for carbon dioxide in the drink . newly formed bubbles join with the old one , resulting in a larger bubble
原来除了玻璃杯上的小裂缝和汽水的杂质可作为成核位置外，气泡本身在上升途中也会成为其他溶解于汽水内的二氧化碳的成核位置，新形成的气泡与旧气泡聚合在一起，便变成更大的气泡。 |
