摘　　要：实验研究了球形钨合金破片的速度衰减规律、爆轰驱动下的变形和破碎、对半无限钢靶的侵彻以及对薄钢靶的贯穿。结果表明:(1)破片长距离(120m)飞行时的衰减系数为常数,阻力系数与破片初速成线性关系;(2)在爆轰驱动下,直径为6.0和7.5mm的破片破碎率为2%～3%,而直径为8.5mm的破碎率为45%;(3)破片长距离飞行后仍有很强的穿甲能力。Tests were performed to investigate the terminal effects of spherical tungsten fragments, i. e., the behavior during long-distance flight, the deformation and break driven by detonation, the penetration of semi-infinite steel targets and the perforation of thin steel plates. The experimental results show that (1) the attenuation coefficient of velocity is constant and the air drag coefficient is a linear function of initial velocity, (2) driven by detonation, the break percentage of fragments with a diameter of 6.0 mm and 7.5 mm is 2%-3%, whereas the break percentage is 45% for the fragments with a diameter of 8.5 mm, (3) the fragments can still perforate thin steel plates after traveling long distances.
