In order to study the combustion process and the movement of propellant in the barrel, a multi - photo x - ray experiment system was designed. four groups of photos under different ignition systems were obtained, and these photos were manipulated with digital image manipulation technology. the gray degree of the photos was averaged, and the information, such as density, velocity of the projectile and the trace - indicating grains and confliction velocity of the propellant against the projectile under the consideration of the velocity of the projectile, was extracted and analyzed quantitatively
本文就利用由多幅脈沖x光攝影技術所獲得的四種不同點火條件下的火炮膛內火藥顆粒群運動狀況的陰影照片，進一步利用數字圖像處理的技術及相關演算法，編制軟體對照片進行了處理，統一了照片的灰度，最終在定量上獲得了不同點火條件下的火藥顆粒的密度分佈規律、彈丸和示蹤藥粒的運動速度以及在考慮到彈丸運動的前提下的火藥顆粒與彈丸的撞擊速度。It is very important to observe the ignition process and movement of the propellant grains directly in the barrel
直接觀察不同點火條件下初始彈道段膛內火藥顆粒群的點火、燃燒以及運動狀態，具有十分重要的理論意義和實際意義。
