The paper by J.M. Dewey (Shock Waves 29(4):583–587, 2019 ) described the development of an Excel-based interface that provides the physical properties of blast waves generated by propane/oxygen explosions. The interface was developed using the data from a nominal 20 ton explosion of an assumed stoichiometric propane/oxygen mixture. Comparisons of data from the interface with measurements of small-scale stoichiometric propane/oxygen explosions show discrepancies. Further studies revealed that the 20 ton explosion was not stoichiometric and had a 43% oxygen deficiency. The interface has been redeveloped assuming that only 57% of the available propane had been detonated. The revised interface produces results which agree with measurements from both the 20 ton explosion and the small-scale (< 1 g) detonations. The revised interface and updated users’ guide are available for downloading.

附录：提供丙烷爆炸产生的冲击波物理特性的接口

JM Dewey 的论文（Shock Waves 29(4):583–587, 2019）描述了基于 Excel 的界面的开发，该界面提供了丙烷/氧气爆炸产生的冲击波的物理特性。该接口是使用来自假定化学计量丙烷/氧气混合物的标称 20 吨爆炸的数据开发的。来自界面的数据与小规模化学计量丙烷/氧气爆炸的测量结果的比较显示出差异。进一步的研究表明，20 吨的爆炸不是化学计量的，并且缺氧 43%。界面已重新开发，假设只有 57% 的可用丙烷已被引爆。修改后的接口产生的结果与 20 吨爆炸和小规模 (< 1 g) 爆炸的测量结果一致。
