- The phenomenon and the mechanism of air entrainment were discussed. 对气泡产生的现象及原因进行了描述、分析。
- Additional, station of gas station, air entrainment is 20 years with the ground. 另外,加油站、加气站用地为二十年。
- Overflow weir is used to control water hammer and prevent air entrainment in long supply pipelines. 在长距离输水管路出口设置溢流堰可以有效控制水击和防止管路脱空。
- Hydraulics model is built by using similar theories, which simulates the process of air entrainment of tapping. 摘要利用相似原理建立水力学模型,模拟了出钢过程中注入流体卷入气体的过程。
- The water surface falls before the flow point of air entrainment and then rises afterwards. 在掺气发生点以前,水面线沿程降低,掺气发生点以后,水面线沿程升高;

- Some special phenomena of flow do harm to the dams, so it is significant to study on it.The characters of air entrainment flow are shown in this paper. 高速水流会发生一些特殊的水流现象,严重影响建筑物的安全,因而对其进行研究是十分必要的。
- The simulation experiment shows that the shorter teeming time is, the less air entrainment of tapping is; the lower teeming height is, the less air entrainment of tapping is. 模拟实验结果表明,注入时间愈短,注流带入的气体量愈少;注入高度愈低,注流带入的气体量愈少。
- Today, air entrainment is recommended for nearly all concretes, principally to improve resistance to freezing when exposed to water and deicing chemicals. 如今,引气几乎在所有的混凝土中使用,用以提高暴露水中混凝土的抗冻性和抗化学腐蚀性。

- With the increase of impinging distance, both the wall spread distance and the thickness of liquid film on the wall was decreased, and the air entrainment near the wall was weakened. 随着碰壁距离增加,喷雾体的壁面扩展度和厚度都有所降低,近壁区的空气卷吸作用减弱;
- The air in the garden was warm and fragrant. 花园里的空气一片温馨。
- The archers sent their shafts through the air. 弓箭手向空中射出利箭。
