水以巨大的气态云团的形式存在，吸收并发出光线，让强大的望远镜可以穿过令人难以置信的空间距离检测到它们。
Different elements or compounds absorb and emit different colors or wavelengths of light, and by studying a star's spectrum, one can divine what its composition might be.
不同的元素或化合物吸收并释放不同颜色的光波，通过对一个恒星的光谱进行研究，我们能够推测它可能的成分。
When electrons jump between these energy levels, they absorb and emit light of particular frequencies.
当这些能级中，发生电子跃迁时，这些电子便吸收并释放出不同特定频率的光。
They also re-emit some of the heat they absorb.
它们也会再次放射走一些已经吸收的热量。
It does this, as the product's name suggests, by passing the LED light through a transparent film peppered with quantum dots, which absorb and re-emit some of it.
正如该产品的名字那样，通过一张添加量子点的透明薄膜去过滤发光两极管的白光，而这些量子点吸收并重新发射其中一些光线，它确实办到了。
These absorb heat, via a link to specially built Windows, and spontaneously emit it to the house when the temperature drops in the evening.
通过与特别建造的窗户相连接，它们可以吸热，并在夜晚温度下降的时候自动把热量释放到房屋里。
As I said earlier, dark matter doesn't emit, absorb, or reflect any type of light.
正如我前面所说，暗物质不会发射、吸收或反射任何形式的光波。
Atoms emit and absorb light of specific wavelengths, as measured in laboratory experiments.
就如同在实验室中所测量到的，原子会放出或吸收特定波长的光。
Dark matters do not emit, absorb or reflect light ray of any wavelength.
暗物质不发射、吸收或者反射任何波长的光线。
Obviously, the physics base of the remote sensing technology is that landmark can reflect, absorb and emit electromagnetic wave.
遥感技术的物理基础是地物对电磁波的反射、吸收和发射特性。
Nerve cells and any cell, the need to breathe, need to absorb and emit.
神经细胞和任何细胞一样，需要呼吸，需要吸收和排出。
The discrepancy is due to greenhouse gases in the atmosphere, which absorb and re-emit infra-red radiation, and thus keep the lower atmosphere, and the surface, warm (see the diagram below).
究其原因，原来是大气中的温室气体造成了这种温度上的差异。温室气体吸收，并再度释放了远红外辐射，使得底层大气与地表保持温暖(参见以下附图)。
Microscopic scales covering the wings absorb ultraviolet light and then re-emit it.
覆盖在翅膀上的微结构吸收紫外线，然后又将其重新发射出去。
