摘要
利用公式ΔU=-0.1196n/λ.计算了不同浓度的甲烷爆炸后体系的温度,进而计算了爆炸产生的压力.当甲烷在空气中的浓度达到爆炸反应的下限浓度5.3%时,爆炸后体系的温度为1232 K,最高压力为4.13 atm.当甲烷在空气中的浓度达到9.5%时(甲烷与空气中的氧气完全反应),爆炸后体系的温度为1815 K,最高压力为6.09 atm.
The temperatures of explosive systems of CH4 at different concentrations were calculated by tormula ΔU=-0.1196n/λ. Then, the pressures were counted. When CH4 concentration in air is 5.3% （low limit of explosive reaction）, the highest temperature is 1232 K, the highest pressure is 4.13 atm; when the concentration in air is 9.5% （ CH4 can be reacted completely with the oxygen in air）, the highest temperature is 1815 K, and the highest pressure is 6.09 arm.
