电爆炸丝在空气中的密度分布是研究电爆炸丝的重要信息。在这项研究中，密度分布的电子，钨原子和空气在不同的时刻重建的基础上的双波长干涉法。实验是在1 kA、0.1kA/ns脉冲电流发生器上进行的。爆炸产物的激光探测图像显示出两层结构，表现出分流放电的情况。拟合的致密芯的膨胀轨迹表明，导线的膨胀在电压下降的瞬间开始。重建的密度反映了爆丝膨胀过程中粒子的分布情况。结果表明，电爆丝芯为管状结构，等离子体通道位于芯体边界附近，其密度分布是研究电爆丝在空气中爆炸的重要信息。在这项研究中，密度分布的电子，钨原子和空气在不同的时刻重建的基础上的双波长干涉法。实验是在1 kA、0.1kA/ns脉冲电流发生器上进行的。爆炸产物的激光探测图像显示出两层结构，表现出分流放电的情况。拟合的致密芯的膨胀轨迹表明，导线的膨胀在电压下降的瞬间开始。重建的密度反映了爆丝膨胀过程中粒子的分布情况。结果表明，丝芯为管状结构，等离子体通道位于芯边界附近。
The density distribution is important information in the investigation of electrical exploding wires in the air. In this study, the density profiles of the electrons, tungsten atoms, and air at different instants were reconstructed based on a two-wavelength interferometry method. The experiment was carried out on a 1 kA, 0.1 kA/ns pulsed current generator, with a fine tungsten wire (10 μm in diameter). The laser probing images of the exploding products showed a two-layer structure, exhibiting a shunting discharge scenario. The fitted expanding trajectory of the dense core indicates that the expansion of the wire starts at the instant of the voltage drop. The reconstructed densities show the distribution of particles in the expansion process of the exploding wire. It is found that the wire core has a tube-like structure, and the plasma channel is located around the core boundary.The density distribution is important information in the investigation of electrical exploding wires in the air.
