| 摘 要： | 通过对电能作火药当量化假设，将势平衡理论用于电热化学炮的内弹道分析。根据常规和电热化学发射的试验结果，初步探讨了势平衡理论在电热化学炮内弹道数据分析中的应用。该方法可以用于确定弹丸运动的阻力系数，确定实际火药力和电能利用系数，评价脉冲放电的作用效能。根据势平衡点参数的变化，可以检测膛内火药燃烧是否有异常现象。

| Abstract: | In the hypothesis of the energy of propellant being equaled by electrical energy, the theory of potential equilibrium in interior ballistics can be used to analyze the interior ballistic processes of electro-thermal chemical gun. Based on the results of conventional and electro-thermal chemical shoot experiments, a data processing method using the potential equilibrium theory was discussed. Tnis method can be used to calculate the drag coefficient of bullet, effective powder force and effective coef-ficient of electrical energy. Based on the change of parameter in the potential equilibrium point, the abnormal phenomena of combustion can be detected. |
