本文论述了“三高”火炮的内弹道特点,研究了内弹道势平衡理论解法以求解“三高”火炮内弹道的有关问题,如弹道特征量的确定,P—t曲线处理的规范化问题,表解法的“一致符合”性能等,与ГАУ表解法相比,表明它所提出的方法对“三高”火炮是方便而准确的实用解法。 This paper discusses the characteristics of the internal trajectory of the “three high” artillery, studies the solution of the theoretical solution of the internal ballistic potential equilibrium to solve the internal trajectory of the “three high” artillery, such as the determination of ballistic features, the standardization of P-t curve processing, Compared with the solution of ГАУ table, this method shows that the proposed method is a convenient and accurate practical solution to the “three high” artillery.
