摘　　要：为了研究超高速碰撞过程中材料处于热力学平衡状态时碰撞闪光强度与碰撞速度的关系,采用理论与实验验证相结合的方法,结果表明碰撞闪光强度I与碰撞速度v遵循指数关系。通过LY12铝弹丸超高速碰撞LY12铝靶实验验证了碰撞闪光强度I与vn的关系,且幂指数n值在3～4间。In order to investigate the degree of intensity of flash dependence on impact velocity during hypervelocity impact when the material was in the thermodynamics equilibrium, the method of theory and experiment were adopted in the paper. Result shows that Impact light flash intensity I and impact velocity v obeys the power law. Experiment confirm that relationship of I and v^n for LY12 aluminum projectile into LY12 aluminum target, the range of n value is between 3 and 4.
