本文介绍用14MeV中子活化法无损测量大口径炮弹炸药密度的原理及方法,并对一批炮弹用活化法与称量法的测盈结果进行比较,其相对误差在±2.5～5％之内。
In this paper, the principle and method of non-destructive measurement of detonation density of large-caliber projectile with 14MeV neutron activation method are introduced. The relative error of a batch of projectiles with the method of activation and weighing is compared within ± 2.5 ~ 5% .
