利用爆炸激波管研究了惰性物质对爆炸行为的影响。众所周知，有必要避免和减少由于惰性物质对爆炸的抑制而造成的爆炸损失。由于氮对汽油爆轰温度的影响可以通过所谓的多通道排放高温计技术来测量，因此氮含量的增加可以明显地有助于降低汽油的爆轰温度。为此，作者测定了水蒸气对汽油爆轰行为的影响，发现水蒸气能明显降低汽油爆轰压力。当蒸汽压力增加到0.1MPa时，由于产生化学计量氢氧混合物爆轰所需的蒸汽，很可能导致爆炸失败。在硝基甲烷和氧气的混合物中加入氮气也能降低爆炸压力。利用多道光谱分析系统（OMA摄谱仪）和多台单色仪进行的光谱测量结果表明，CH3O、CH自由基辐射强度的快速下降可能是导致反应失败的原因。
The article is aimed to study the impact of some inert materials on the explosion behavior by using the explosion shock tube. As is known, it is necessary to avoid and decrease a loss of the explosion caused by the inhibition on inert materials on the explosion. Since the influence of nitrogen on gasoline detonation temperature can be measured by means of the so-called multi-channel emission pyrometer technique, nitrogen content increase can obviously contribute to the lowering of the detonation temperature of gasoline. For this reason, the author measured the influence of vapor on the gasoline detonation behavior and found that the vapor can obviously decrease the explosion pressure. When the vapor pressure increases to 0.1 MPa, it is likely to lead to failure of the explosion due to the generating vapor for stoichiometry hydrogen-oxygen mixture detonation. The explosion pressure can also be decreased when nitrogen is added into a mixture of nitromethane with oxygen. The results of spectra measurement gained by using the multi-channels analysis system (OMA spectrograph) and multi-monochrometers indicate that the fast decreasing of CH 3O, CH radical radiation intensity may leads to the reaction failure.
