Starting in 1980 , hko maintains the hong kong standard time with a caesium beam atomic clock . to check the hong kong standard time , people can make use of hko s six - pip time signals broadcast by the radio television hong kong or hko s telephone information enquiry system 市民可利用由天文臺提供給香港電臺的六響報時信號或使用天文臺的查詢資料電話系統來核對香港標準時間,亦可透過互聯網使用天文臺的網絡時間服務,把電腦時鐘對準香港標準時間。

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、氪等惰性氣體會順風移動而迅速稀釋。大部份揮發物,例如碘、銫及碲,在到達大氣層時,已凝結成粒子。
