| 摘 要： | 本文导出哨声波有质动力的一个公式。该公式表明,当ω<Ωe/2时,有质动力倾向于把电子推向强波场区,从而在波的传播路径上形成密度脊;当ω>Ωe/2时情况正相反,有质动力倾向于在波的传播路径上形成密度槽。这就表明,weibel的结果1]只是当ω《Ωe时本文所得到的结果的特殊情形。

| Abstract: | A formula of ponderomotive force of whistler waves has been derived in this paper.It shows that when the wave frequency ω<Ωe/2 (Ωe: the gyro-frequency of the electrons),the electrons intend to move into the region where the wave amplitude is larger.As a result,a density crest is formed along the propagation path of the wave.When ω>Ωe/2,the situation is just reversed,the ponderomotive force intends to sweep out the electrons from the region where the wave field is more intense,resulting in formation of a density through along the propagation path of the wave.Therefore,the Weibel's results are just the special case (ω<<Ωe) of the results presented here. |
