英语翻译摘要：水中氨氮含量是水体受污染程度与自净能力的重大指标,纳氏试剂分光光度法测定水中氨氮,方法简便,快速,灵敏度高

译文如下：
Abstract: the water ammonia nitrogen content is water contaminated with the degree of the major indexes self-purification nano's reagent spectrophotometry, ammonia nitrogen in water method is simple, rapid, high sensitivity, is testing the water content of ammonia nitrogen is the most commonly used method. This paper adopts Leonard's reagent spectrophotometry relatively accurate measurements of fuyang normal college ammonia in west qinghe water nitrogen content, testing results show that the content of ammonia nitrogen in water 0.513 muon g/mL, content is on the high side. As the campus living areas crowded, contains a lot of ammonia nitrogen organic life water discharge into water, the microbial decompose role in, make ammonia nitrogen content increase greatly.
