氧气

Ozone can kill harmful bacteria and virus quickly in air or water, oxidizes odorous gases and may result in production of fresh oxygen.

臭氧可把水和空气内的有害细菌快速消灭，把一些有嗅味的气体氧化，从而产生新鲜氧气。

Oxygen is a colorless,taseteless,odourless,gaseous chemical element.

氧气是一种无色，无味、无臭的气体状的化学元素。

In hatcheries, early ontogenetic stagesare often maintained in high densities and （data on oxygen demand andammonia-N release rates ）are necessary for a correct dimensioning ofstructures and routine of cultivation.
