摘　　要：采用"颗粒不变收缩芯模型"研究了梯黑铝装药中Al的酸解反应动力学行为,考察了反应温度、硫酸浓度及炸药粒度对反应速率的影响。结果表明,A l的酸浸过程符合动力学方程g(x)=1-(1-x)1/3=kt,为化学反应控制类型,表观活化能为42.392 kJ/mol。在此基础上,经线性回归分析,发现表观反应速率常数k与硫酸初始浓度C0及炸药粒径1/r20成正比例关系。The reaction kinetic of drawing Al from high explosive of TNT/RDX/Al was approached using shrinking unreacted core model.The effect of temperature,concentration and size of explosive on reaction speed was investigated.The results show that the leaching process of drawing Al meets kinetic equation g（x）=1-（1-x）1/3=k t.The leaching kinetic is controlled by chemical reaction,and activation energy is 42.392 kJ/mol.Regression analysis was applied based on theory model,finding that apparent reaction speed is linear with regards to the concentration of H2SO4（C0） and the size of explosive（1/r20）.
