报道了一种同时测定水和底泥中微生物氨氧化速率(V-a)和亚硝酸盐氧化速率(V-n)的新方法。该方法基于对无缓蚀剂培养体系中DIN(亚硝酸盐、硝酸盐和铵)的时间序列变化的数学建模分析。与传统的含有特定抑制剂的方法相比，该方法不受抑制剂的影响，可以同时准确地测定瞬时和平均的V-a和V-n。实际应用表明，该方法能很好地测定水样和沉积物中Va和Vn的动态变化。
This study report a new method for simultaneously determining microbial ammonia oxidation rate (V-a) and nitrite oxidation rate (V-n) in water and sediment. This method is based on mathematical modeling analysis for the time series variation of DIN (nitrite, nitrate, and ammonium) in an incubation system without an inhibitor. Compared to the traditional methods with specific inhibitors, this method is not affected by inhibitors and can determine both instantaneous and average V-a and V-n accurately and simultaneously. Practical application indicated that this method can well determine the dynamic variations in Va and V-n in both water and sediment samples.
