摘　　要：后效期内的火炮弹丸特性研究在火炮工程实践中有重要意义,而其中弹丸后效期时间和作用距离2个重要参数,一直没有较为成熟实用的测量方法。提出了一种火炮弹丸后效期时间和作用距离的测量方法,采用高速数字摄像技术,运行图像处理软件,分别得到弹带离开炮口时刻和弹尾离开冲击波时刻的弹丸位置坐标和时间,两位置坐标之差就是弹丸后效期作用距离,两时间之差就是弹丸后效期时间长度,并以某小口径火炮为测量对象,采用该测量方法成功地测量出了靶场射击时的弹丸后效期时间和作用距离。The research on the characteristics of artillery projectiles within the after-effect period is of great importance to the artillery engineering practice. At present, there is not a mature and practical method for the measurement of two important parameters, such as after-effect duration and operating range. A measuring method is proposed to measure the after-effect duration and operating range of artil- lery projectiles. In the method, a high speed digital camera technology and an image processing software are used to obtain the projectile position coordinates and time when the band leaves the muzzle and the projectile base leaves the shock wave. The difference between the two position coordinates is the operating range of projectile in the after-effect period, and the difference between the times when the band leaves the muzzle and the projectile base leaves the shock wave is the duration of after-effect period. The method was used successfully to measure the after-effect duration and operating range of projectile for a small cali- ber artillery in a range test.
