According to Urbanski's finding in a solid explosive with a density of less than the theoretical maximum density (TMD), the detonation velocity increases if the air contained in the explosive gets replaced by a non‐explosive liquid. In order to quantify this observation, the detonation velocities for RDX in combination with ten non‐explosive liquids were calculated using the EXPLO5 code (V6.05.04). It could be shown that pressing out the air of a high‐explosive powder and replacing the voids with a non‐explosive liquid such as ethylene glycol, water or glycerin helped to increase the final detonation velocity.

固体炸药与非爆炸性液体混合物爆轰速度的计算研究

根据Urbanski在密度小于理论最大密度（TMD）的固体炸药中的发现，如果炸药中所含的空气被非爆炸性液体代替，则爆炸速度会提高。为了量化此观察结果，使用EXPLO5代码（V6.05.04）计算了RDX与十种非爆炸性液体的爆炸速度。可以证明，将空气中的高爆炸性粉末挤出并用非爆炸性液体（例如乙二醇，水或甘油）代替空隙有助于提高最终爆炸速度。
