目的　研究提高杀伤战斗部威力的技术途径． 方法　应用弹道发射枪发射不同质量与直径的钢和重金属钨破片侵彻靶板， 测定破片的着速， 并比较其侵彻性能． 结果　根据测得的破片速度及侵彻性能的试验结果， 可以确定重金属破片具有非常优越的侵彻性能． 结论　当战场上目标的防护能力加强后， 在导弹、火箭弹等战斗部上装填重金属杀伤元素可有效地提高其杀伤威力 Objective To study ways to improve the power of anti-personnel warheads. Methods Ballistic launchers were used to launch tungsten and tungsten fragments with different mass and diameter to penetrate the target plate. The penetration velocity was measured and the penetration performance was compared. Results Based on the measured results of the fragment velocity and penetration performance, it was confirmed that the heavy metal fragment had a very superior penetration performance. Conclusion When the protective capability of the target on the battlefield is strengthened, loading heavy metal anti-personnel elements on warheads such as missiles and rockets can effectively increase its lethality
