摘　　要：立式激波管中实测了几种碳氢燃料-空气混合物直接起爆的临界起爆能和云雾爆轰波胞格尺寸。数据表明,燃料气液两相云雾爆轰的临界起爆能与当量比呈-"U"型曲线关系,而最小临界起爆能则在富燃料一侧,这与气相云雾爆轰结论是一致的。采用爆轰波胞格尺寸衡量这几种燃料云雾相对爆轰敏感度的结论和临界起爆能也是一致的。In this paper the critical initiation energy and the cell sizes of hydrocarbon-air mixtures were measured in shock wave tube. Results demonstrate that the relationship of critical initiation energy and equivalence ratio shows an'U' shape curve, the minimal critical energy is obtained when equivalence ratio is slightly larger than 1. The conclusion is similar to the gaseous detonation. The experimental result of cell sizes, which was investigated by using smoked foil, is also similar to the critical initiation.
