利用方波发生器电流源研究了电流密度在0.25×108~3.26×108 Amp/cm2范围内金丝的爆炸行为。测量了不同电流密度下导线电阻与累积能量和作用的关系，并与一个简单的爆丝理论模型和Kerr池照相研究结果进行了比较。实验结果表明，达到最大线阻时间的总能量随着电流密度的增加而增加，可能会超过正常蒸发能量的三倍。电流密度越大，任意点处的瞬时导线电阻越小。阻力抑制首先出现在汽化后的区域。在较高的电流密度下，观察到这种影响发生在逐渐较早的阶段，直到并包括发生熔化的点。
A square‐wave generator current source was used to study the behavior of gold wires exploded by current densities in the range of 0.25×108 to 3.26×108 amp/cm2. Measurements of wire resistance vs cumulative energy and action at various current densities are compared with a simple theoretical exploding wire model and the results of Kerr cell photographic studies. Experimentally, the total energy input to the time of maximum wire resistance increases with current density and may exceed by threefold the normal vaporization energy. Also, the instantaneous wire resistance at any point is smaller with a larger current density. The resistance depression is first apparent in the region following vaporization. At higher current densities, the effect is observed to occur at progressively earlier phases up to and including the point at which melting occurs.
