采用代表体积元建模方法，建立了与实际高聚物粘结炸药（ Polymer Bonded Explosive， PBX）细观结构高度相近、能反映炸药颗粒和微孔隙随机分布、可以任意调整填充率和孔隙率的有限元计算模型，并计算分析了孔隙率对PBX热导率的影响。结果表明，随着孔隙率增大，PBX的有效热导率呈指数减小。

A representative volume element ( RVE) model was developed to investigate the thermal conductivity of three-phase pol-ymer bonded explosive ( PBX) , and the fraction and distribution of the fillers and pores were taken into consideration.The influ-ence of porosity on the thermal conduction of PBX was analyzed.Results show that the thermal conduction of PBX decreases expo-nentially with the increase of porosity.
