反硝化作用 meaning in Chinese
denitrification
Examples
- It also could denitrify nitrate companying the formation of nitrite
以硝酸钠为氮源时能进行反硝化作用。 - It was showed that temperature and quality of inlet water would affect the activity of denitrification
受进水水质和低温天气的影响，反硝化细菌制剂的净化作用及反硝化作用不能充分发挥。 - The exchange rates of no3 - n at the sediment - water interface were mainly controlled by the difference of the concentrations between the pore water and the overlying water . may be the nitrification or the denitrification and the degradation of organic matter were the key processes during the exchange of din and the processes were controlled by the temperature and the do . 3
扩散过程可能是控制no3一n界面交换速率的主要过程之一，浓度差的大小决定了其速率快慢;而发生在界面上的有机物的降解和硝化或反硝化作用可能是控制n岛一n 、 n仇一和nh4一界面交换的主要过程，温度和do浓度是控制这一交换过程速率的主要因子。 - Abstract : mainly reviewed distribution of organic nitrogen , early diagenesis ( such as counteract - eutrophication , nitrification / denitrification et al . ) , the controlling factors of nitrogen cycling ; and the relationship between nitrogen and ecological system in sediments in recent years , which may contribute to research the nitrogen marine biogeochemical process
文摘:主要阐述海洋沉积物中氮的存在形式与分布、氮的早期成岩和去营养化作用、硝化和反硝化作用以及氮与生物特定种群的关系等,探讨了影响海洋沉积物中的氮循环的主要因素,分析了海洋沉积物中的氮与生态系的关系,以期对研究氮的海洋生物地球化学过程有所帮助 - Severe fires can often cause changes in successional rates and soil hydrologic functions , degradation of soil physical properties , alter c : n ratios , and result in subsequent nutrient loss through accelerated erosion , leaching or denitrification , and alterations in microbial populations and associated process can occur
高强度火烧往往能引起演替频率的改变，土壤物理性质退化，水文功能发生改变，改变c n比，加剧侵蚀、淋溶和反硝化作用，导致养分流火，微生物数量及其相关过程发生变化。
