This proved that nitrourea was a more suitable reactant than urea to synthesize Keto-RDX.

由此表明了在生成RDX酮的反中，硝基脲上比脲更为合的反形。

This paper presents the studies on the reaction form of urea or nitrourea which condenses with nitrolysis fragments of urotropine to form Keto-RDX in nitrating agents.

通改变加来研究脲或硝基脲在硝化剂中与乌洛托品硝解碎片进行缩合反的形。
