The mutagenicities of these extracts after nitrosation were about 5 times higher than that of the original shrimp sauce.
亚硝化处理后，其诱变性较虾酱直接亚硝化时高5倍左右。

This paper discussed the influence on the biochemical oxygen demand, ammoniation and nitrosation by barium of different levels in water.
本文就不同浓度的钡对天然水的生化需氧过程、氨化及亚硝化过程的影响进行了探讨。
