： To explore the influence rule of octogen （ HMX ） solid content ， system temperature ， HMX particle size ， HMX particle gradation and functional additives etc.on the rheological properties of 2 ， 4⁃dinitroanisole （ DNAN ） /HMX suspensions ， the appar⁃ ent viscosity of DNAN/HMX suspensions under different material state conditions was investigated by a digital viscometer. Re⁃ sults show that the suspension presents Newtonian fluid characteristics when the solid content is 3%. Apparent viscosity of the suspension can be described with Ostwald⁃deWaele model when the HMX solid content is 12%-30% ， and the value of non⁃ Newton index n is decreased from 0.842 to 0.374. The influence of temperture on the apparent viscosity can be described by the Arrhenius equation when the temperture is in the range of 95-116 ℃ ， and the activation energy E a increases from 25.97 kJ ∙ mol -1 to 30.17 kJ ∙ mol -1 . The apparent viscosity decrases as the particle size increases. When the particle gradation ratio of 999.5 μ m particle size to 132.6 μ m is 2 ∶ 1 ， the apparent viscosity reaches the minimum and the solid content is up to 80%. Functional ad⁃ ditives N ⁃methyl⁃4⁃nitroaniline （ MNA ） and tri （ β chloroethyl ） phosphate （ CEF ） make the apparent viscosity of the suspensions decrease ， while dehydrated sorbitol monostearate polyoxyethylene ether （ Tween 60 ）， microcrystalline wax⁃80 （ MV80 ）， cellu⁃ lose acetate butyrate （ CAB ）， and thermoplastic polyurethane -5720 （ TPU 5720 ） make the the apparent viscosity of the suspen⁃ sions increase.

为了探讨辛烷（HMX）固体含量、体系温度、HMX粒径、HMX颗粒级配和功能添加剂等因素对2，4-二硝基尼松（DNAN）/HMX悬浮液流变性能的影响规律，用数字粘度计研究了不同物质状态下DNAN/HMX悬浮液的表观粘度。结果表明，当固体含量为3%时，悬浮液具有牛顿流体特性。当HMX固体含量为12%-30%时，悬浮液的表观粘度可以用Ostwald-deWaele模型描述，非牛顿指数n从0.842降低到0.374。当温度在95-116℃范围内时，温度对表观粘度的影响可用Arrhenius方程描述，活化能EA从25.97kJ∙mol-1增加到30.17kJ∙mol-1。表观粘度随着颗粒尺寸的增加而降低。当粒径999.5μm与132.6μm的颗粒级配比为2∶1时，表观粘度达到最低，固体含量达到80%。功能添加剂N-甲基-4-硝基苯胺（MNA）和磷酸三（β-氯乙基）酯（CEF）使悬浮液的表观粘度降低，而脱水山梨醇单硬脂酸酯聚氧乙烯醚（Tween 60）、微晶蜡80（MV80）、纤维素乙酸酯丁酸酯（CAB）和热塑性聚氨酯-5720（TPU 5720）使悬浮液的表观粘度增加。
