The results of common chemical analysis indicated that the NO3-N movement was coresponded with the water condition.
结果表明，NO3—N的移动同降雨、灌水以及整个土壤系统中的水分状况密切相关。
N5+ in NO3- on the surface of the film is deoxidized into N in amine, and N in amine disappear after calcination.
研究发现，吸附在膜上的NO3-中的N5+被还原成胺类低价态的N，焙烧后该类氮化物中的N消失。
However, the increase of the two parameters above were not simultaneously, the increment of soil NO3-N accumulation was much higher than that of total N accumulation in wheat plants.
施用氮肥能提高小麦拔节期和成熟期植株全氮积累量和土壤NO3-N积累量，但两者并非同步增加，土壤NO3-N积累量增加的幅度远远大于植株全氮积累量的增长幅度。
