分别在有约束(激波管实验)和无约束(野外实验)条件下测定了丁烷与空气混合物最敏感成分的临界起爆能,并利用zel’dovich理论将激波管内数据外推到野外,结果发现理论计算结果与实测数据基本吻合. The critical detonation energies of the most sensitive components of the butane and air mixtures were determined under confinement (shock tube experiments) and unconstrained (field experiments) conditions, respectively, and the shock tube data were extrapolated to the field using the zel’dovich theory. The results show that the theoretical calculation results are basically consistent with the measured data.
