密集的铝，铜，钨的导电性进行了评估，使用爆炸线放电在水中。爆炸丝的半径和电阻的演变测量与温度的直接高温估计一起。的电导率进行评估的基础上的测量和它们的密度依赖性进行比较，在一个固定的温度下的理论预测。结果表明，无论何种材料，在5000 K时，电导率都有一个最小值，约为固体密度的3%。
Conductivities of dense aluminum, copper, and tungsten are evaluated using exploding wire discharges in water. Evolutions of the radius and the electrical resistance of exploding wire are measured together with direct pyrometric estimation of the temperature. The conductivities are evaluated based on the measurements and their density dependence is compared with theoretical predictions at a fixed temperature. The results indicate that regardless of materials, the conductivity has a minimum around 3% of solid density at temperature of 5000 K.
