目的研究弹头终点效应对创伤的影响．方法根据流体力学和弹药学理论，分析弹头的直径、外形、结构、质量和终点速度对创伤试验结果的影响．结果试验结果证实，小口径弹头具有更好的创伤效应．结论小口径（５～６ｍｍ），较高初速（９００～１０００ｍ／ｓ）和小质量（３～４ｇ）的弹头是当今的发展方向．
Objective To study the effect of warhead end effect on trauma. Methods Based on fluid mechanics and ammunition theory, the effects of warhead diameter, shape, structure, mass and end velocity on wound test results were analyzed. Results The test results confirmed that the small-caliber warhead has a better traumatic effect. CONCLUSIONS Smaller caliber (5 ~ 6mm), higher initial velocities (900 ~ 1000m / s) and small mass (3 ~ 4g) warheads are the current development directions.
