【摘要】 作者分别用圆形和方形爆轰管,通过改变惰性气体的比例和圆锥管道的锥角,对H₂-O₂和C₂H₂-O₂系统进行了爆轰临界直径的实验研究,得到了不同稀释浓度下方管中爆轰波熄灭的临界直径,验证了Mitrofanov.V.V.和Soloukhin,R.I.以前得到的结果（d_c/λ=10）,也得到了圆锥管道中不同锥角θ对临界直径的影响（d_c/λ-θ）,并用流管理论对实验结果作了初步的分析。更多还原

【Abstract】 The experimental studies on the critical tube diameter were carried out in H2-O2 and C2H2-O2 mixtures with circular and square detonation tube respectively. The experiments were conducted with changing the ratio of the inert gases and the angle of conical tube. The critical tube diameter for different diluted concentration with square tube was obtained and the previous result found by Mitrofanov, V. V.and Soloukhin. R.I. (dc/λ= 10)was confirmed. The influence of different cone angle θ on critical tube diameter for circular tube (dc/λ-θ) was also obtained and the results discussed with the stream theory.更多还原
