This paper deals with the synthesis of ultrafine diamond ( ufd ) under high pressure and high temperatures generated by negative oxygen balance explosive detonation. the mechanism of synthesis ultrafine diamond by detonation standpoint is presented
本文從理論和實驗兩個方面對利用負氧平衡炸藥爆轟產生的游離碳，在高溫、高壓下相變為納米金剛石（ ultrafinediamond簡稱ufd ）作了初步探索。 -
The charge used in the experiment is a mixture of tnt and rdx ; the influences of its density, slenderness ratio on the yield of ufd are experimentally investigated
並從裝藥的密度、裝藥的長徑比、混合裝藥中rdx顆粒尺寸對爆轟合成納米金剛石的影響作了實驗研究。 -
The ufd is characterized by transmisson electron microscopy ( tem ) and x - ray diffraction ( xrd ) ; the results showed that the ufd commonly exhibit a spherical shape, and it is cubic crystal
Ufd通過透射電鏡（ tem ）觀察和x射線衍射分析進行特性表徵， tem觀察到金剛石外貌大多為球形，尺寸約70nm ，但大多形成微米級的團聚體。 -
The experimental results indicate that the yield of ufd increases with increasing the density, slenderness ratio of charge. ufd synthesis is related to the particle size of rdx
裝藥密度、長徑比的增加都有利於ufd的得率的增加，裝藥粒度對合成ufd有影響。 -
The process of ufd establishment is discussed according to the three stages of detonation propagation. the factors that influence the synthetic ufd process are theoretically analysed. a hermetically spheric container, which can bear internal pressure that the detonation of 100 gramme charge, is designed for the experiment
在理論方面針對爆轟合成納米金剛石機理研究存在的兩大異議進行探討分析，提出了自己的看法；從爆轟傳播的三個階段對ufd的形成過程進行論述；對合成ufd的三個影響因素：爆壓、爆溫和保護介質作了定性分析。
