摘　　要：通过扫描电镜(SEM)和液体静力称量法,研究了1,3,3-三硝基氮杂环丁烷(TNAZ)的微观结构及乙酸丁酸纤维素(CAB)、N-甲基-对-硝基苯胺(MNA)、2,4-二硝基苯胺(DNA)、聚四氟乙烯(PTFE)4种添加剂对TNAZ微观结构和装药密度的影响,并进一步研究了MNA、DNA对TNAZ摩擦感度、撞击感度以及爆速的影响。结果表明,TNAZ熔融结晶后的密度下降了9.3%;CAB、PTFE的加入降低了TNAZ的装药密度;而MNA、DNA的加入不仅提高了TNAZ的装药密度,还降低了TNAZ的摩擦感度和撞击感度;且适量加入MNA和DNA,能够提高TNAZ/HMX基炸药的装药密度,从而提高其爆速。The crystal micro-mechanism of 1, 3, 3-trinitroazetidine （TNAZ） and the effect of additives, including cellulose acetate butyrate （ CAB）, N-methyl-P-nitro-aniline （ MNA）, 2,4-dinitroaniline （DNA） and teflon （ PTFE）, on the crystal micro-mechanism and charge densities of TNAZ were studied by an SEM and density ts. The effects of MNA and DNA on the friction sensitivity, impact sensitivity and detonation velocity of TNAZ were also tested. Results show that the density of TNAZ reduces after melting crystallization ; addition of CAB or PTFE reduces the charge density of TNAZ. However, adding MNA or DNA not only improves the charge density, but also reduces the friction sensitivity and impact sensitivity of TNAZ. Adding appropriate amount of MNA or DNA can improve the charge density and explosion ve- locity of TNAZ/HMX based explosives.
