摘　　要：对铝粉直径从几十纳米到几十微米的几种含铝炸药，进行了小尺寸装药条件下炸药加速金属平板实验，用激光速度干涉仪测量了金属平板自由面速度，比较了几种炸药对不同厚度金属平板的加速时间和加速能力。分析了铝粉在炸药爆轰中的反应情况。在小尺寸装药下，铝粉加入炸药和铝粉尺寸大小对炸药爆轰性能有明显影响。纳米铝粉使炸药作功能力有较大提高。含铝炸药爆轰中，铝主要在爆轰后期与爆轰产物反应。The metal plate acceleration experiments were carried out with small size aluminized explosive pillars.The aluminized explosives have spherical aluminum particles of different diameter from 50nm to 50μm.Using VISAR interferometer,we measured the free surface velocity of the metal plate.The capacities and time of aluminized explosives accelerating the melt plates of different thickness are compared.The reactions of aluminum are analyzed.For the small size pillars of aluminized explosive,the diameter of aluminum particles has influence on explosive detonation performance.The aluminum particles of nanometre diameters increase the working capacity of the explosive.The aluminum particles react mostly with the detonation products in the detonation process.
