抜粋

Local measurements of impulse breakdown plasmas in an atmospheric air using ruby-laser scattering revealed that pressure as high as 12 atm (electron density蝱1.3ȕ1024m-3and temperature蝱3.4 eV) and an electric field of 2.8ȕ104V/m were reached in the arc channel just after the beginning of the discharge (t=0.4 Ɓsec), and that they rapidly approached respective values at DC discharge in the air. The pressure in the arc channel was found uniform across the channel radius each time, and the initial pressure in, and the expansion velocity of, the arc channel at t=0.4 Ɓsec, were enough to cause the resulting shock-wave expansion at later times.
