Even if it is not, the material that has been found could have been used to make a "radiological" weapon, by blowing it up and scattering it around a city using conventional explosives.

即便不是这样，通过在城市周围用传统炸药对原料充气使其分散开，这些已经被发现的原料可以用来制作一种辐射性武器。

For many years researchers have been trying to develop a synthetic material with the same light-scattering properties as an opal, by etching patterns into various materials. That approach has failed.

多年来研究者们一直致力于开发一种与猫眼石一样有散射特性的合成材料，他们在各种各样的材料中蚀刻图案，但是都无功而返。

Produced during mutual action of light and material, Raman spectroscopy is a kind of testing method which use inelastic scattering light.

拉曼光谱技术是一种基于光与物质的相互作用产生的非弹性散射光来进行检测的方法。
