The experimental results revealed that 60% of cell decay in a nitrifying system was caused by activity decrease and 40% was caused by cell death. In a heterotrophic system, however, activity decrease was responsible for 80% of cell decay, and the other cell decay for 20% was caused by cell death.

结果表明，硝化系统细菌在衰减过程中由细胞活性降低引起的衰减约占60%，由细胞死亡引起的衰减约占40%；而在异养系统中由活性降低引起的衰减和由细胞死亡引起的衰减分别为80%和20%。

Fertilizer Entec26 contained DMPP (new type of nitrification inhibiter) could also decrease soil nitrate leaching.

证明在高灌水量条件下，尿素+玉米秸杆处理，使土壤矿质氮固定和微生物氮增加，降低了土壤硝态氮的下层累积和向下淋洗；施用含新型硝化抑制剂DMPP的肥料Entec26也能降低土壤硝态氮的向下淋洗。

The influence of internal recycle ratio and influent loads on biological nitrogen removal was discussed.

结果考察工艺的启动挂膜性能以及硝化液回流比和进水负荷对脱氮效果的影响。

Soil net N nitrification would increase with the increase of the %FNDA of Lespedeza bicolor. Lespedeza bicolor could fix a large amount of N〓, but was also likely to increase the N leaching loss.

胡枝子固氮作用越强，土壤有机氮的净硝化量就越大，胡枝子在从大气中获取大量〓的同时，很可能会增加氮素的淋溶损失量。
