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

由此表明了在生成RDX酮的反应过，基脲上比脲更为合的反应形式。

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.

通过改方式来研究脲或基脲在化剂与乌洛托品解碎片进行缩合反应的形式。
