摘要

摘要: 通过实验对C2H2-O2-Ar 混合气体的临界起爆能量和爆轰临界管径进行测量，基于临界起爆能量计算爆炸长度，分析爆炸长度与爆轰胞格尺寸及临界管径之间的规律，并对各种物质临界起爆能量与诱导区长度的关系进行了研究。结果表明：C2H2-O2混合气体，其爆炸长度与胞格尺寸之间的关系为R0=26，加入50%和70%氩气稀释的混合物，两者的关系分别为R0=37.3和R0=54.8；C2H2-O2-Ar 混合气体爆炸长度与爆轰临界管径之间的关系为R0=2DC；对于70%浓度氩气稀释的C2H2-O2混合气体，其爆轰波具有稳定的一维ZND结构，临界起爆能量正比于诱导区长度的3次方。

Abstract: The critical initiation energy and critical tube diameter of C2H2-O2-Ar mixtures were measured in the experiment. The relationship between explosion length, which is theoretical calculated from critical energy, and detonation cell size as well as critical tube diameter was analyzed. The relationship between critical initiation energy and induction zone length was also investigated for each mixture. The results show that, for C2H2-O2 mixtures, a parametric relationship between explosion length and cell size is R0=26, however, this function is changed to R0=37.3 and R0=54.8 when 50% and 70% argon diluted, respectively. The relationship between critical tube diameter and explosion length is R0=2DC. The results indicate that detonation has stable one-dimension ZND structure when argon dilution up to 70%, and a linear relationship is found between critical energy and the cube of induction zone length.
