| 摘 要： | 开展了固态脉冲形成线相关材料的研究，基于脉冲形成线的特性参数与材料介电性能之间的关联性，可实现固态脉冲形成线材料的筛选和评估。对不同类型材料介电性能的比较和固态脉冲形成线性能的分析表明:介电常数可调的微波陶瓷是制备固态脉冲形成线较为理想的材料。以Ba-Nb-Ti微波陶瓷制备的固态脉冲形成线可获得高压脉冲前沿5~6 ns，脉宽为13 ns，脉冲平顶为5~6 ns，击穿场强超过17.5 kV/mm。

| Abstract: | The paper investigates the dielectric materials for compact pulse forming lines. According to the interrelation between parameters of pulse forming lines and dielectric properties of ceramic materials, the strategies of the material choice and assessment are presented for the solid-state pulse forming lines of dielectric materials. The microwave ceramics characteristic of adjustable dielectric constants are found to be relatively ideal candidates. The solid-state pulse forming line fabricated from the Ba-Nb-Ti microwave ceramics, can output pulses with a rise-time of 5-6 nm, a pulse length of 13 ns, and a flat top of 5-6 ns, and its breakdown strength is more than 17.5 kV/mm. |
