| 1. | The major controlling influence is the inflow of a cold, dry, air mass . 主要支配的影响是干冷气团之流入。 |
| 2. | As the rotor turns clockwise the charge is sealed off and compression begins . 当转子顺时针方向转动时,送进的气团就被封闭,并开始压缩。 |
| 3. | The products of combustion and of industrial processing are contained with a confined air mass . 燃烧和工业过程产物被封闭在局部气团的地区中。 |
| 4. | Weather systems associated with air masses are usually several hundred to a thousand or miles across and move from west to east . 天气体系和与之有关的气团,常常绵亘几百到几千英里,并自西向东移动。 |
| 5. | A low - pressure system along the california coast 一个低气压气团正沿加里福尼亚海岸运动 |
| 6. | A low - pressure system along the california coast . . 一个低气压气团正沿加里福尼亚海岸运动. . |
| 7. | It moves as a mass , pushing on air in other places 它形成气团移动,把空气推移到另一个地方。 |
| 8. | Sometimes the air masses which meet at a front cause storms 有时在锋面相遇的气团会造成暴风雨。 |
| 9. | A front is a transition area between the cold and warm air masses 锋或锋面是指冷暖气团之间的过度带。 |
| 10. | Boundary of the air mass 气团的边界 |
