摘要
本文研究了在垂直于磁场和等离子体流动的重力场中具有剪切流动的电流片的稳定性。这种由剪切流动和重力联合作用所引起的混合模,称为流动重力模不稳定性。作为一个例子,还讨论了弱重力场情况下激发流动重力模不稳定性的临界条件。
The stability is studied of a current sheet with a sheared flow in a gravitational field which is perpen dicular to the magnetic field and plasma flow. This mixing mode caused by a combined role of the sheared flow and gravity is named the Streaming Gravity Mode Instability'. As an example, the critical condition for the streaming gravity mode instability is discussed in a weak gravitational field.
