The Effect of Concentration of Ar on Formation of Cellular Structure in H_2-O_2 Detonation
H_2—O_2爆轰时Ar浓度对产生胞格结构的影响

The H_2-O_2-Ar detonation experiments were conducted witha square detonation tube. The regular cellular structure was obtained in detonation of H_2-O_2 mixture diluted by Ar. In addition, the critical curve of formation of cell was also obtained and it shows consistent tendency while compared with explosion limit. Aside from these, the distance from point of ignition to where cell was formed as well as the length of region of cellular structure were measured. Finally, the restrained action of concentration of Ar on H_2-O_2 detonation was discussed.
