denitrification

denitrification的音标为[dɪ"nɪtɪfɪˈeɪʃn] ，基本翻译为“脱氮作用”，速记技巧为：“denit”=脱氮，“-fication”=作用。

Denitrification这个词的英文词源可以追溯到拉丁语“denitridae”，意为“denitrid”，指的是一种特定的微生物群落，它们能够将含氮化合物转化为氮气，从而去除氮污染。

变化形式：在英语中，denitrification通常被简称为“denitr”或“denitrify”，而其复数形式则为“denitrifications”。

相关单词：

1. Nitrogen removal：氮去除，指的是通过各种方法将环境中的氮元素从污染物中分离出来，包括生物脱氮、化学脱氮和物理脱氮等。

2. Nitrogen cycle：氮循环，指的是自然界中氮元素不断循环的过程，包括氮气的形成、氨的合成、含氮化合物的转化等。

3. Nitrogen fixation：氮固定，指的是通过生物或化学过程将大气中的氮气转化为含氮化合物，例如尿素、氨等。

4. Denitrogenation：脱氮，指的是去除环境中的氮污染物的过程。

5. Denitriding：去氮污染，指的是通过各种方法去除环境中的氮污染物的过程，包括生物修复、化学修复和物理修复等。

6. Denitrification rate：脱氮速率，指的是单位时间内环境中脱氮的速率。

7. Denitrification potential：脱氮潜力，指的是环境中能够进行脱氮作用的微生物的数量和活性。

8. Denitrification process：脱氮过程，指的是微生物通过将含氮化合物转化为氮气来去除氮污染的过程。

9. Denitrification treatment：脱氮处理，指的是通过各种方法去除废水中的氮污染物的过程。

英文小作文：

Denitrification is a crucial process in environmental engineering, which reduces nitrogen oxides to nitrogen gas through microorganisms. It plays an important role in reducing nitrogen pollution and improving water quality in agricultural fields. In addition, denitrification equipment can effectively protect agricultural fields from nitrogen oxide emissions, and denitrification treatment is an effective method to reduce nitrogen oxide emissions from factories and vehicles. Therefore, environmental engineers and farmers should pay attention to denitrification process and technology, which is essential for maintaining a healthy environment and sustainable agriculture.
