但空气在接近裂缝的时候速度会越来越快，杰弗里·兰迪斯说，他是美国宇航局在克利夫兰·格伦研究中心的一位物理学家。
But air picks up speed as it approaches a fissure, said Geoffrey Landis, a physicist at NASA's Glenn Research Center in Cleveland.
但是经验告诉物理学家们不可以打开任何一扇窗子，不然空气就会冲出去，使房间变成真空。
But experience has taught the physicists never to open a window because, when they do, all the air rushes out and leaves the room a vacuum.
基本物理学理论上，空气越稀薄情况下，任何物体的耐性都会减少，因此球路也会因海拔高度不同而有所变化。
It's the basic physics that the air is thinner and the resistance to any projectile is less so the flight path of the ball will be different at high altitude.
科学家说他们预计在冬季和夏季会有更强的风暴，很大一部分原因是因为物理学原理：暖空气能够容纳更多的水蒸气。
Scientists say they expect stronger storms, in winter and summer, largely because of the physical principle that warmer air can hold more water vapor.
环境物理学的兴起，从声、光、热、振动和空气动力等方面入手，为治理环境带来了广阔的前景。
The development of physics has brought a new and broad views to harness the environmental problems on sound, light, heating, vibration and air dynamics.
同样，球物理学会微妙的不同，球将飞更快一点，更直，因为有较少的空气阻力。
Likewise, the ball physics will be subtly different; the ball will fly a bit faster and straighter since there is less air resistance.
从物理学的角度看，drag指物体在穿过某种流体媒介(如空气)时遭到的阻力，而zero drag则是描述物体不受任何阻力的理想形状。
In physics, drag refers to the resistance experienced by an object moving through a fluid medium (such as air).
这些物理学现象包括人摄入肺中的空气量、喉头声带的震动以及声波在声道中传播。 典型的合成语音听上去像机器人，因为人类在解剖学上的结构很难被复制。
They include the intake of air into one's lungs, the mechanics of vocal folds in the larynx, and the movement of acoustic waves through the vocal tract.
当我进入大学的时候，我对物理学和飞行的空气动力越来越有兴趣，致使我最终攻读了机械工程学位。
By the time I entered college, I had become more interested in the physics and aerodynamics of flight, which has led me to pursue a degree in mechanical engineering.
