摘　　要：在确定多孔材料状态方程的基础上,从多孔药型罩材料在与爆轰波相互作用中受到冲击波加载及随后卸载引起的温升、多孔药型罩在压合时的塑性变形引起的温升以及聚能粒子流伸展过程中的塑性变形引起的温升等3个方面,对聚能粒子流温升进行了估算。利用MATLAB软件对多孔铜和密实铜药型罩形成的聚能粒子流和聚能射流的温升进行计算,计算结果表明:由于多孔铜药型罩在与爆轰波相互作用中受冲击波加载及随后卸载引起的温升,使得聚能粒子流的温升明显高于密实铜聚能射流的温升。To estimate theoretically the temperature rise of shaped charge particle jet, the temperature rise was calculated based on the equation of state of the porous material determined. The temperature rise includes heating due to the shock wave transferred into the porous liner by the explosive detonation wave and due to the plastic work performed during porous liner and shaped charge particle jet elongation. The temperature rises of the porous copper shaped charge particle jet and the solid copper shaped charge jet were calculated by the MATLAB software. The calculated results show that： the temperature rise of the porous copper shaped charge particles jet was significantly higher than that of the solid copper shaped charge jet,because of the contribution that the shock wave transferred to the porous liner by the explosive detonation wave.
