摘要
Measurements of the static breakdown voltage Vs of air and nitrogen have been made under uniform field conditions for values of N in the range 1·65×1019-9·9×1019 cm -3 and 0·33×1020 less-than-or-eq, slant Nds less-than-or-eq, slant 2·64×1020 cm -2 (N is the gas number density and ds the sparking distance.) The measurements show that Paschen's Law, Vs=f(Nd s), is obeyed in nitrogen, but an interesting deviation is revealed in air. The observed deviations from Paschen's Law are in good agreement with the deviations which were calculated by Daniel et al. in 1969 from measurements of the spatial growth of pre-breakdown ionization currents.
