一前言 狭缝照相机每次可得一张非常清晰的大尺寸照片,取得弹丸在某特定空间的飞行姿态,研究弹丸部件分离变形及其损坏机理,测定弹丸的偏航和章动角,转速及飞行速度;另外,当作一般扫描摄影用时可测得弹丸的加速度和弹丸碰靶时的负加速度。这些资料和参数对于兵器的设计和改进、定型生产和装备作战部队都是至关紧要的依据。而采用 A foreword The slit camera can obtain a very clear and large size photograph at a time, obtain the projectile’s flight attitude in a specific space, study the separation deformation and the damage mechanism of the projectile components, measure the yaw and nutation angles of the projectile, the rotation speed and Flight speed; In addition, when used as a general scanning photography projectile can be measured when the projectile and projectile target acceleration. These materials and parameters are of crucial importance to the design and improvement of weapons, stereotyped production and the deployment of combat troops. And adopted
