给出了放电毛细管内等离子体绝热不定常零维数学模型，该模型考虑了金属引爆丝的电阻变化过程、毛细管材料的烧蚀电离细节及等离子体的非理想特性。利用该数学模型对毛细管的放电过程进行了数值模拟，得到了等离子体参数的动态变化过程。计算结果与相应的实验值进行了比较，对理论值与实验值的符合程度作了讨论，证明了该模型的工程实用性。
The mathematical model of unsteady plasma in discharge capillaries is given. The model takes into account the resistance change process of metal detonation wire, the ablation ionization details of capillary materials and the non-ideal properties of plasma. The discharge process of capillary was numerically simulated by this mathematical model, and the dynamic process of plasma parameters was obtained. The calculated results are compared with the corresponding experimental values. The coincidence of theoretical values and experimental values is discussed. The engineering practicability of the model is proved.
