本文应用冲量位及态能位作为P—t曲线及P—V曲线坐标的态函数这种新的研究方法,引出了冲量势及态能势这两种判别过程性质从压力变化趋势的标志量并建立了内弹道势平衡理论,该理论主要包括以下五个组成部分: 1)应用内弹道基本方程的态能势及冲量势论证势平衡点的存在,物理意义及相应的弹道条件; 2)应用热力学第二定律论证势平衡点的热力学性质及存在的普遍性; 3)根据势平衡点的弹道条件导出各有关弹道量之间的关系式; 4)应用统计平均厚度的概念论证势平衡点的火药已然部ψ_e即代表火药增班面变化的突变点,业论证了与密用爆发扶所同P—t曲线的拐点具有相同的概念; 5)以势平衡点的火药已过部分We及压力冲量Ie为基础,采用了相对压力冲量Z=I/Ie 代替几何燃烧定律所引用的相对厚度Z’=δ/δ_o,建立实际气体生成规律的函数以代替几何燃烧定律的形状函数,为弹道解法建立新的体系打下基础。
In this paper, we use impulse position and energy level as the state function of P-t curve and P-V curve coordinate. This new research method leads to the impulse potential and state potential, And establishes the theory of internal ballistic potential equilibrium. The theory mainly includes the following five components: 1) The existence of potential equilibrium points, the physical meaning and the corresponding ballistic conditions are discussed by applying the state potential and impulse potential of the basic ballistic equations; 2) The second law of thermodynamics is used to demonstrate the thermodynamic properties and the universality of the equilibrium point. 3) The relation between the relevant ballistic quantities is derived according to the ballistic conditions of the potential equilibrium point. 4) The concept of statistical average thickness is used to demonstrate the potential equilibrium point Has indicated the same concept as the inflection point of the P-t curve; 5) that the gunpowder at the potential equilibrium point has passed through the part of We and Based on the pressure impulse Ie, a relative pressure impulse Z = I / Ie is used instead of the relative thickness Z ’= δ / δ_o cited in the law of geometric combustion to establish a function of the actual gas generation law instead of the geometry combustion law Function to lay the foundation for the establishment of a new system of ballistic solution.
