密集等离子体是利用水中爆炸丝放电产生的。测量了爆炸过程中等离子体半径、电导率、温度和水中冲击波的变化。铝，铜，钨的电导率与理论值进行了比较。为了评估状态方程，激波和等离子体边界的轨迹与数值计算进行了比较。结果表明，流体力学行为对状态方程模型敏感。从丝放电的电压-电流特性讨论了密度-温度图中暖密态的可控性。
Dense plasmas are produced using exploding wire discharges in water. Evolutions of radius, electrical conductivity, temperature of plasma and a shock wave in water accompanied with the explosion, are measured. Conductivities of aluminum, copper, and tungsten are compared with theoretical ones. To evaluate the equation of state, trajectories of the shock wave and the plasma boundary are compared with numerical calculations. Results show that the hydrodynamic behaviors are sensitive to the models of equation of state. Controllability of warm dense state in density-temperature diagram is discussed from the voltage-current characteristics of the wire discharges.
