摘　　要：在固体电热化学炮 ( SPETCG)的内弹道计算过程中 ,人们多把等离子体源以电能的形式或以带修正系数的内能项直接结合到火炮内弹道零维模型上进行简化计算 .本文从固体电热化学炮内弹道一维模型出发 ,在适当假设的前提下推导出了一维耦合模型 ,使其对内弹道耦合过程以更精确的描述 ,并对其该模型计算的结果进行了讨论 .In simulation of solid propellant el ectriothermal chemical gun (SPETCG), some methods, such as taking plasma as a fo rm of electric energy or a shape of internal energy with an amendable coefficien t, were used usually in the zero-dimension model. This paper offers a one-dime nsion integrating model of SPETCG based on proper hypothesis, which will describ e the internal ballistic process of SPETCG more accurately. Also, some calculati on and discussion of the results are conducted.
