通过真空电爆丝实验，测量和分析了分层结构中暗、亮横向层的密度分布和能量沉积。结果表明，在电压崩溃后296 ns，暗层和亮层区域的面密度差约为2 × 1017/cm 2。这种差异对应于暗层和亮层之间的能量沉积差异为0.2eV/原子，这可能是由爆炸期间±10%的电阻率扰动引起的，正如结合气柱膨胀模型和热力学模型所建议的那样。
The density distribution and the energy deposition in dark and light transverse layers from stratification structures were measured and analyzed from electrical exploding wire experiments in vacuum. It is demonstrated that the differences in the areal density of the dark layer and light layer regions were about 2 × 1017/cm2 at 296 ns after voltage collapsed. This difference corresponded to an energy deposition difference of ∼2 eV/atom between the dark and light layers, which likely arises from a ±10% resistivity perturbation during the explosion, as suggested by combining a gas column expansion model and a thermodynamic model.
