【摘要】 以 X射线衍射仪测得的晶体学数据计算了六硝基六氮异伍兹烷的四种晶型 (α- HNIW1/ 2 H2 O,β- HNIW,γ- HNIW和 ε- HNIW)的晶体密度 ,同时根据 GJB772 A- 97,40 1.1所规定的密度瓶法实测了上述四者的密度。计算值分别为 1.992 g/ cm3 、1.989g/ cm3 、1.918g/ cm3 及 2 .0 44 g/ cm3 ,实测值分别为 1.937g/ cm3 、1.983g/ cm3 、1.918g/ cm3 及 2 .0 35 g/ cm3 ,计算值比实测值分别高 0 .0 5 5 g/ cm3 、0 .0 0 6g/ cm3 、0 g/ cm3 及 0 .0 0 9g/ cm2 。更多还原

【Abstract】 The crystal density ( ρ c and ρ m ) of four polymorphs ( α HNIW1/2H 2O, β HNIW, γ HNIW and ε HNIW) of HNIW was obtained. ρ c was calculated on the basis of crystal parameters given by X ray diffractometers. ρ m was determined according to GJB772A 97,401.1 using density bottle methods. The ρ c values are 1.992 g/cm 3, 1.989 g/cm 3, 1.918 g/cm 3 and 2.044 g/cm 3 respectively, and the ρ m values are 1.937 g/cm 3, 1.983 g/cm 3, 1.918 g/cm 3 and 2.035 g/cm 3 respectively. ρ c s are 0.055 g/cm 3, 0.006 g/cm 3, 0g/cm 3 and 0.009 g/cm 3 respectively higher than ρ m .更多还原
