摘要

摘要: 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。

Abstract: An isothermal time-dependent zero dimension model of plasma in a discharge-capillary is developed in this paper. The variation of the resistance of metal wires, the ablation and ionization details of capillary materials and the non-ideal characters of the plasma are considered in this model. The discharge process of the capillary is simulated by this model, and the dynamic processes of the plasma characters are obtained. Simulation and experimental results are compared. The agreement of the theory and the experiment is discussed; it proves the engineering feasibility of this model.
