Astronomers detected a bright fluorescent signal, caused by radiation from the nearby star being absorbed by methane and released as light.
天文学家探测到了强荧光信号，该信号来源于甲烷气体吸收附近恒星辐射而发出的光线。
In this paper, a method for quantitative determination of spectral distributions of primary radiation from X-ray tubes for diffraction and X-ray fluorescent spectral analysis is presented.
本文提出了衍射或荧光分析用的X射线管原级X射线谱强度分布的定量测定方法。
Warning—In addition to other precautions, never look directly at the fluorescent UV lamp because UV radiation can damage the eye.
警告——除了前面提到的注意事项，由于紫外辐射会损伤眼睛，绝对不要直接看紫外灯。
Invisible ultraviolet or infrared radiation. Black light causes fluorescent materials to emit visible light and is used to take pictures in the dark.
看不见的紫外线或红外线。黑光使荧光物体发出可见光，用于黑暗中拍照。
These gases absorb and give off electromagnetic radiation in a much less complex way than other substances, a property exploited in their use in fluorescent lighting devices and discharge lamps.
比起其它的物质来，这些气体吸收和放出电磁辐射的方法要简单得多。
