Methods for chemical analysis of spodumenite and lepidolite concentrates - the atomic absorption spectrophotometric method for the determination of rubidium oxide and caesium oxide contents 锂辉石,锂云母精矿化学分析方法原子吸收分光光度法测定氧化铷和氧化铯量
Inert gases such as xenon and krypton will travel downwind while diluting rapidly . some of the volatile substances , such as iodine , caesium and tellurium , will have already condensed into particles by the time they reach the atmosphere 氙、氪等惰性气体会顺风移动而迅速稀释。大部份挥发物，例如碘、铯及碲，在到达大气层时，已凝结成粒子。
