摘　　要：用铁板凹槽装填乳化炸药,通过离子探针法测得不同装药截面积和不同装药曲率条件下乳化炸药爆炸传播速度,分析弯曲装药条件下装药直径和装药曲率对爆轰波在乳化炸药中传播速度的影响。结果表明,爆轰波传播速度随着装药直径的二次方和曲率半径的减小而线性衰减,当装药直径或曲率半径小到某一临界值时其爆轰反应中止。通过大量实验数据计算得到乳化炸药特定曲率半径和装药直径条件下的爆轰波传播速度计算的经验公式。The emulsion explosives were charged into the curved groove machined on an iron plate.The detonation velocities of the emulsion explosives were measured by using the shorting pins in the cases of different charge cross-sectional areas and different charge curvatures.And the influences of the charge diameters and the charge curvatures on the detonation propagation velocities in the emulsion explosives were analyzed.It is shown that the detonation velocities decrease linearly with the decreasing of the charge curvature radii and the charge diameter square.When the charge diameter or the curvature radius reduces below a certain critical value,the detonation reaction ceases.Based on the experimental data,an empirical formula was proposed for calculating the detonation velocity of the emulsion explosives in the condition that the curvature radius and the charge diameter were given.
