a series of novel c10 higher carbon amino sugar derivatives are synthesized for the first time.
首次报道了新型c10高碳糖胺基衍生物的合成。
amino sugar nitrogen is special, which content of subterranean disposal was higher than land disposal in sheep and cattle dung, while horses dung had no significant differences4.
氨基糖态氮含量比较特殊,羊粪和牛粪为埋入地下处理高于堆置于地表处理,而马粪则无明显差别。
also, the total nitrogen, amino sugar nitrogen and ammonium nitrogen had significant positive relation with nitrogen absorption contents of maize.
