Wave Characteristics of Moving Striations

移動縞の波動特性を理論的に取り扱った。従来の理論では,電子温度の緩和長さと放電パラメータ間の関係はあまり簡単ではなかったが,電子のエネルギー平衡の式を検討することにより,緩和長さは電場と電子温度のみによって表現できることが判った。この関係を使用することにより,移動縞の特性はガスの種類,電場,電子温度,圧力をもって記述することができ,これらの放電パラメータを用いて優勢な移動縞につきその存在領域を検討した。The wave characteristics of moving striations are theoretically treated in this paper. The relationship between the relaxation length for the electron temperature and the discharge parameters has so far been given in a rather complicated description in the theory of moving striations, but the relaxation length for the electron temperature, it must be pointed out, can be expressed only in terms of the electric field and the electron temperature by making investigation into the equation of the energy balance for electrons. Thus, using this relationship, the wave characteristics of moving striations are described with the sort of gas, the electric field, the electron temperature and the pressure of gas. The domain of existence for the dominant moving striations is shown in relation to discharge parameters
