A study was made of the influence of ion viscosity and ion hea t conductivity on the drift instability of a weakly collisional plasma of finite pressure in a magnetic field. Drift oscillations, whose phase velocities in the direction of the magnetic field are of the order of the ion thermal velocity, were considered. Instability region boundaries and growth rate s were determined. The influence of ion viscosity and heat conductivity leads to a widening of the instability regions. In the stability regions, the given effects result in damping of the oscillations. The corresponding damping rates were determined.
磁場中の有限圧力の弱衝突プラズマにおけるドリフト不安定性に対するイオン粘性とイオン熱伝導率の影響について研究を行った。磁場方向の位相速度がイオン熱速度のオーダーであるドリフト振動を考察した。不安定性領域の境界と成長率を決定した。イオン粘性と熱伝導率の影響は不安定性領域の拡大をもたらす。安定領域では、これらの効果は振動の減衰をもたらす。対応する減衰率を決定した。
