摘　　要：为利用雷电驱动Z箍缩产生聚变,调查了相关脉冲压缩技术,尤其是新型的磁通压缩电流放大技术。本文提出一个0维模型,用于描述文献中的电流切换型等离子体套筒驱动磁通压缩电流放大实验,模型计算的结果与实验符合很好。模型成功的关键是其中包含一个定性先升后降的开关电感模型。推测开关断路过程中等离子体壳层的长度先增后减对应于电感的先升后降,这需进一步通过1维和2维建模模拟来确认。To use the lightning driving Z-pinch to produce fusion,we investigated some pulse compression techniques,especially a new type of magnetic flux compression current amplification technique.In this paper,a zero-dimensional model is proposed to describe the current-switching type liner driven magnetic flux compression current amplification experiment in the literature.The calculation results of the model are in good agreement with the experiment.The key to the success of this model is that it contains a qualitatively rising and then falling switching inductance model.We speculate that the first increase and then decrease of the length of the plasma shell during the opening of the switch corresponds to the first increase and then decrease of the inductance,which needs to be confirmed by one-dimensional and/or two-dimensional modeling and simulation.
