该文建立了固体工质电热化学炮(SPETCG)内弹道一维两相流模型。
The one dimensional two phase flow model of solid propellant electrothermal chemical gun (SPETCG) is established in the paper.
由于该炮在电热化学炮的基础上加入轻质气体这一理想工质，因而能大大改善弹丸后部的压力分布，提高火炮弹丸的初速。
Because joined light molecular weight gas in Elctrothermal Chemical Gun, the pressure distribution in projectile base is improved and the projectile velocity enhanced.
