We decided to try another reducing agent, vitamin C.

我试试另一种还原剂——维他命 C。

The important thing is that developers include reducing agents: chemicals that generally donate electrons to other compounds during a chemical reaction.

重点是显影剂里包含还原剂，它能在化反应中给其他化合物提供电。

Jacobs was studying whether the TB drug isoniazid was being inactivated by the presence of a particular amino acid, cysteine, which in chemical terms acts as a reducing agent, by donating electrons.

Jacobs 之前一直研究为何肺结核药物异烟肼会被氨基酸和半胱氨酸灭活，而异烟肼在化反应中通过失电，还原剂的作用。

We saw that just like the other reducing agent, it in combination with isoniazid sterilized the culture.

我看它跟另一种还原剂相同，跟异烟肼一道将这些细胞灭活。

It is hard to decarbonise when steel is made from virgin iron ore in conventional blast furnaces, because coal is used both as fuel and a reducing agent.

在传统高炉中， 使用原生铁矿石制造钢铁时难以实现脱碳，因为煤炭既作为燃料又充当还原剂。

In the past, carbon was mainly used as fuel and reducing agent in iron - making.

过去，碳主要用作炼铁的燃料和还原剂。
