摘要：

Flute mode oscillations are excited in a single-ended Q-machine plasma by applying three phase voltage to electron emissive grids (coated with BaO) heated by the thermal radiation from the hot plate. Synchronous quenching is also observed: A relation a2+αb2=const. is obtained between the amplitudes a and b of the spontaneous and excited flute modes (whose frequencies are f0and fex, respectively. The factor α depends on the frequency discrepancy and the position of observation: α=0.17 and 0.3 for (f0−fex)⁄f0=0.28 and 0.13, respectively. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
