| 摘 要： | 依据Herrmann状态方程和斜冲击波关系估算了多孔材料药型罩压垮之前的冲击温升,求解了经过冲击压缩卸载后材料的声速。给出了多孔材料药型罩聚能射流的形成条件。初始冲击温升会使材料的声速和强度降低,从而使多孔材料聚能射流形成射流的高速和低速条件降低。

| Abstract: | Compressibility of the porous material considered,shocking temperature rise of the porous liner before collapse was derived based on the Herrmann equation of state,the material sound speed was calculated after the shock wave released.The formation condition of the jets produced by shaped charge with porous liners was presented.The initial shocking temperature rise will make the sound speed and material strength decrease,so that the value of velocity limits of formating jet reduce. |

| Keywords: | mechanics of explosion porous liner shaped charge jet coherency sound speed |
