- But if the surrounding air has a dew point of 3oC, the mould will not sweat. 若模具周围的空气是露点3℃的干燥空气,模具便不流汗。
- 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。
- Extremely cold cryogens such as hydrogen and helium can even freeze or solidify the surrounding air. 极低温液体,如氢和氦甚至能冷冻或凝固周围空气。
- The cold "boil-off"gases condense the moisture in the surrounding air, creating a highly visible fog. 低温汽化气体浓缩周围空气里的水份,产生非常显著的雾。
- 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。
- When this hot water vapour mixes with the surrounding air, a cloud in the form of a contrail may appear. 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。
- The only way we may gain altitude is if the surrounding air current is ascending enough to offset our gradual sinking. 唯一能够使我们获得高度的方式,是我们周遭的气流上升力的足够抵销我们逐渐下沈的力量。
- An aircraft, especially a balloon or dirigible, deriving its lift from the buoyancy of surrounding air rather than from aerodynamic motion. 浮空器从周围空气的浮力而不是从空气动力获得提升力的航空器,特指气球或飞船
- 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。
- These nanoparticles then oxidise back into silicon oxides, drawing oxygen fromthe surrounding air. 这一单分子随即氧化形成氧化硅。从周围的空气中夺走氧。
- The cold “boil-off” gases condense the moisture in the surrounding air, creating a highly visible fog. 低温汽化气体浓缩周围空气里的水份,产生非常显著的雾。
- Those vibrations result in the compression and rarefaction of the surrounding air. 这些振动会导致周遭空气的压缩及稀少。
- As a bonus, the steam also smothers the flames by diluting the amount of oxygen in the surrounding air. 这种办法的另一个好处在于,产生的水蒸汽能够稀释周围空气中的氧气浓度,从而抑制火焰的燃烧。
- An aircraft,especially a balloon or dirigible,deriving its lift from the buoyancy of surrounding air rather than from aerodynamic motion. 浮空器从周围空气的浮力而不是从空气动力获得提升力的航空器,特指气球或飞船
- 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。
- Mirror-walled skyscrapers, whose reflective glasses reduce glare as well as heat inside, raise the temperature of the surrounding air. 虽然摩天高楼的外墙用反光玻璃能够减轻太阳的直射,降低室内的温度,但是这些玻璃墙提高了周围大气的温度。
- A flexible,nonporous bag inflated with a gas,such as helium,that is lighter than the surrounding air,that causes the bag to rise and float in the atmosphere. 气球,一种有弹性、无孔充气后膨胀的气囊,如充入比周围空气轻的氦气后能使气囊上升并漂浮在大气中。
- The air just emerging from the nozzle is highly energetic and, as it moves away from the nozzle, it entrains some of the surrounding air which tends to slow the mass down. 气流刚出喷嘴时能量最高,随着飞行距离的增加,周围的空气被卷进来,会使运动着的空气减速。
- The salty lamp may help to reduce your allergic source, sterilize, and improvement surrounding air quality, maintenance ion environment balance and so on. 盐灯可以帮助减少你的过敏源、杀菌,并且改善周围空气品质、维持离子环境的平衡等。
- A flexible, nonporous bag inflated with a gas, such as helium, that is lighter than the surrounding air, that causes the bag to rise and float in the atmosphere. 气球一种有弹性、无孔充气后膨胀的气囊,如充入比周围空气轻的氦气后能使气囊上升并漂浮在大气中
