The method of choice used by most terrorists for achieving political goals remains the utilization of explosive devices and there is always visible evidence at a crime scene after the deployment of such devices. Given favorable circumstances, forensic analysis can determine the cause of the explosion - the type of the explosive device, the means of detonation, the type and mass of the explosive charge that has been used and perhaps provide information to lead to the identity of the individual who may have constructed or deployed the explosive device, etc. Evidence of an explosion may take the form of a crater or other damage which may provide some information facilitating and estimating the mass of explosive material used. This paper reports the findings obtained by performing experimental explosions of known charges on a concrete surface, in order to establish the correlation between the charge weight and the effects of the explosion. Known masses of explosives were fired and the dimensions of craters made by explosions were measured. Five empirical equations for estimation of the explosive charge mass from crater dimensions were used.
大多数恐怖分子实现政治目标所选择的方法仍然是使用爆炸装置，而且在部署此类装置后犯罪现场总会留下明显证据。在有利的情况下，法医分析可以确定爆炸原因——爆炸装置的类型、引爆方式、所使用炸药的类型和质量，甚至可能提供信息以查明可能制造或部署爆炸装置的人员身份等。爆炸的证据可能表现为弹坑或其他损坏形式，这可能提供一些有助于估算所用爆炸材料质量的信息。本文报告了通过在混凝土表面对已知装药进行实验性爆炸所获得的结果，以便确定装药重量与爆炸效果之间的相关性。发射了已知质量的炸药，并测量了爆炸形成的弹坑尺寸。使用了五个根据弹坑尺寸估算炸药装药质量的经验公式。
