该文讨论测量全喉缩膛口射出霰弹飞行速度的两种方法，并对测量结果进行分析。一是借助高速摄影设备测量霰弹的膛口飞行速度，结果表明，其飞行速度平均为４８０ｍ／ｓ，弹子的纵向扩散速度平均为４７ｍ／ｓ，横向扩散速度平均为２９ｍ／ｓ；二是采用区截铝箔靶装置测量单个霰弹子飞行速度，结果表明，２０ｍ射距时平均为３６１ｍ／ｓ，３０ｍ射距时平均为３０７ｍ／ｓ，４０ｍ射距时平均为２５７ｍ／ｓ，因弹子穿过四层铝箔纸，其受箔靶的影响量平均约为１６％。
This article discusses two methods of measuring the shotgun flight speed at the full throat, and analyzes the results. First, the shooting speed of the shotgun was measured by means of high-speed photographic equipment. The results showed that the average flight velocity of the shot was 480m / s, the longitudinal velocity of marbles was 47m / s on average, and the average lateral velocity of diffusion was 29m / s. The results showed that the average shot velocity was 361m / s at 20m shot distance, 307m / s at 30m shot distance and 257m / s average shot length at 40m shot distance, Aluminum foil, which is affected by the amount of foil target, is on average about 16%.
