A new type of emulsion explosive sensitized by hydrogen‐storage has been invented previously. To better understand the role of hydrogen in emulsion explosives, the detonation experiments with different gas storage were conducted. Several gases, such as helium, oxygen, and nitrogen, were taken into account. Brisance tests, detonation velocity tests, and underwater detonation experiments showed that the high‐pressure hydrogen can improve the power and energy of emulsion explosive. The adiabatic compression of different gases was calculated. The pressure and temperature of the gas in GMs were obtained. Hydrogen has better compression performance than the other gases. Combining experiments and theoretical calculations can obtain that, hydrogen plays an important role in hot spots formation rate and emulsion explosive energy, and nitrogen and oxygen have little contribution to the energy of emulsion explosive, while helium is difficult to store in GMs and has a negative influence on the performance of emulsion explosive.

不同气体对乳化炸药中储气玻璃微气球性能的影响

以前已经发明了一种通过储氢敏化的新型乳化炸药。为了更好地理解氢在乳化炸药中的作用，进行了不同储气量的爆炸实验。考虑了几种气体，例如氦气，氧气和氮气。引爆测试，爆震速度测试和水下爆震实验表明，高压氢气可以提高乳化炸药的功率和能量。计算了不同气体的绝热压缩率。获得了GMs中气体的压力和温度。氢气比其他气体具有更好的压缩性能。结合实验和理论计算可以得出，氢在热点形成速率和乳化炸药能量中起着重要的作用，
