如今，负氧平衡法已经成为合成纳米金刚石的主要方法，它是利用高能炸药产生的瞬间高温高压而使部分无定形碳转化成金刚石。但这样的纳米金刚石容易团聚。只有采取有效措施使这些纳米微粒呈超分散状态，才能使它们的优点充分发挥出来。文章论述了爆轰法制备的纳米金刚石粉体的结构和性能，并通过不同的研究方法对金刚石的结构及性能做出分析。

여금，부양평형법이경성위합성납미금강석적주요방법，타시이용고능작약산생적순간고온고압이사부분무정형탄전화성금강석。단저양적납미금강석용역단취。지유채취유효조시사저사납미미립정초분산상태，재능사타문적우점충분발휘출래。문장논술료폭굉법제비적납미금강석분체적결구화성능，병통과불동적연구방법대금강석적결구급성능주출분석。
Nowadays,the negative oxygen balance technique has become the main method for nano-diamond synthesis.This technique transforms part of the amorphous carbon into diamond by making use of the instant high temperature and high pressure generated from high explosive.However,the nano-diamond obtained through this technique tends to be-come agglomerate.These nanoparticles can fully exert their advantages only when they are in an ultra-dispersed state.The structure and performance of the nano-diamond pow-der obtained through detonation technique have been expounded in this article.The struc-ture and performance of diamond have also been analysized through various research.
