So in this saliva, we found two enzymes that can reproduce the effect of the saliva, meaning oxidising polyethylene.

In case you didn't know, black tea is oxidised when green tea isn't.

不知道的话，红茶是经过氧处理的，而绿茶则未经此过程。

So this is again fluorine with sulphur. So you are going to oxidise the sulphur, probably to sulphur tetrafluoride or sulphur hexafluoride.

因此， 里再次涉及氟与硫的反应。 将会氧硫，很可能会将其氧为四氟硫或六氟硫。

Bioleaching relies on the metabolism of certain naturally occurring bacteria, such as Acidithiobacillus ferrooxidans, which produce oxidising agents that dissolve metals into solution.

生物浸出依赖于某些天然细菌的代谢，例如氧亚铁硫杆菌，它能产生氧剂， 将金属溶解在溶液中。

He was a man of fifty, a sort of sea–wolf, with big eyes, a complexion of oxidised copper, red hair and thick neck, and a growling voice.

人有五十岁，是个久经海上风波的老水手，说话挺冲，看样子是个不大好交往的人。他圆睁着两只大眼睛，面如青铜，头发棕红，身材魁梧，一点也不象人们在社会上经常接触到的人。

并不难，只是有点繁琐，有些方需要注意，它氧得很快，所以在准备的时候，用柠檬摩擦它就很明智。

When zinc is exposed to the acid in the lemon juice, the acid oxidises, or removes electrons from the zinc, and the resulting positively charged zinc ions move in the solution.

当锌暴露于柠檬汁的酸的时候，酸就会氧，或者是把锌里面的电子移除，所以带正电荷的锌离子就会在溶液中移动。
