摘要
利用冲击大电流通过水中的一段金属丝进行水中电爆炸实验 ,通过对水中电爆炸的放电电压、电流波形测量以及高速阴影摄影和扫描摄影 ,记录了冲击波的传播、汽泡增长和等离子体半径的时间特性 ;由不同充电参数的实验 ,得到了一些基本规律。比较了水中电爆炸和空中电爆炸的异同 ,揭示了水中电爆炸存在的放电模式。
High speed shadow photography and streak photography are used to study underwater wire exploding. The exploding and its effects such as shock wave, plasma and cavity pictures are obtained and shown. Some regularities are obtained according to those pictures and the time characteristics of the current and the voltage for discharging. The differences between underwater and in air wire exploding and some mode of discharging underwater are introduced in this paper.
