摘      要：This work deals with an experimental study of a Cu planar wire array(PWA)in air and water under the stored energy 300-1200 J.A single Cu wire is adopted as a controlled *** configurations of PWA and a wire with the same mass(cross-section area)but the different specific surface areas(15-223 cm^(2)g^(-1))are *** transient process is analyzed using high-speed photography in combination with the results of optical emission and *** characteristics revealed that PWA always has a higher electric power peak,early but higher voltage peak,as well as faster vaporization and ionization process than the single-wire *** to three times stronger optical emission could be obtained when replacing the single-wire with PWA,indicating a higher energy-density state is ***,in both air and water,single-wire load tends to develop a transverse stratified structure,while PWA is dominated by the uneven energy deposition among ***,the synchronism and uniformity of the PWA explosion are discussed.
