当热的水汽遇上周围的空气便可能形成雾，以尾流形式出现。 |
| 3. | However , mirror walled skyscrapers raise the temperature of the surrounding air and affect neighboring buildings
但是，镜面的摩天大楼会提高周围空气的温度并会对附近的建筑物产生影响。 |
| 4. | Worse of all , their reflective glasses coated with silver or gold mirror films raise the temperature of the surrounding air
更糟糕的是，大楼外墙那涂著银色或金色薄膜的反光玻璃使周围的气温大大提高了。 |
| 5. | Worse of all , their reflective glasses coated with silver or gold mirror films raise the temperature of the surrounding air
更糟糕的是,大楼外墙那涂着银色或金色薄膜的反光玻璃使周围的气温大大提高了。 |
| 6. | Within the third dimension , the balloon has a center , and its surface expands into the surrounding air as it inflates
在三维空间中，气球确实有个中心，而在它膨胀的时候，表面也是向周围的空间扩张出去的。 |
| 7. | It is also safer to use than ethanol and gasoline , as it is less likely to evaporate into the surrounding air ( which creates a fire risk )
而且，丁醇比起乙醇和汽油更加安全，因为其挥发到周围空气中的可能性较小（挥发气体可能造成火灾） 。 |
| 8. | For sedentary pursuits in temperate weather , people have no need to sweat : excess metabolic heat easily moves from blood vessels at the surface of the skin into the surrounding air
人在温和天气中从事静态活动时，不需流汗：新陈代谢产生的多馀热量很容易从皮肤表面的血管散入周遭空气。 |
| 9. | However , the scientists found that the clouds also increase the heat of the surrounding air and have contributed about half of the temperature rise blamed for the glaciers " melting
但是，科学家们发现，这些云层同时增高了周围空气的热度。而导致冰川融化的气温升高，有一半是这么造成的。 |
| 10. | Light winds tend to confine the cool air locally , preventing it from getting warm by mixing with surrounding air . moisture in the air keeps the heat on the ground from radiating away . hence , dry air cools off faster than moist air
另外，由于空气中的水份会阻挡地面的热能向外散发，所以潮湿空气令地面冷却得较慢，而乾燥空气则令地面冷却得较快。 |
