英文摘要： With the rapid development of pulsed power technology in military and civilian fields, miniaturization,solid-state and repetition frequency of pulsed power system are the inevitable trend. As the important part of pulsed power system, the pulse forming line filled with water or oil is becoming one of the key bottlenecks in the miniaturization of pulsed power system. Due to high dielectric constant and high electric breakdown strength of glass ceramics, it shows a good potential for the pulse forming line application. In the project, compact solid-state pulse forming line will be fabricated through investigating large-size glass ceramics, electrode and encapsulation process. repetitive pulse peculiarity and the lifetime of the pulse forming line will be studied. The relation between the pulse properties of pulse forming line and dielectric properties of glass ceramics, electrode and encapsulation will be built. The damage machanism of pulse forming line under repetitive frequency will be discussed.It will provide theoretical guidance for the development of repetitive solid-state pulse forming line and promote the progress of pulsed power technology.
