The change in the intensity distribution of the spectrum of microwave oscillations was studied by vary. ing the gap length between the sparking electrodes, using a cavity-wavemeter. The same analysis was made by varying the pressure of the gas in the gap, and the effect of changing the kind of electrode materials and the gas was examined. The gap length versus power relation changes systematically, as the wave-length or the gas pressure is varied. It was found also that the efficiency of the oscillations depends largely on electrode materials; only a few kind of metals, namely aluminium, magnesium and beryllium have high efficiencies, while almost all others have very low ones. A special kind of relaxation oscillation is efficient for generating an impulsive oscillation of microwaves when these metals are used.
