stream geometry

河道斷面形狀-
Using the two - stream fluid model, the linear dispersion relation is derived assuming a two - dimensional spatial geometry. two cases are considered, one is that the 2d spatial geometry is defined by the plane containing the two counterstreaming electron populations and the perturbation wave vector ( referred as the xy plane ), and the other is that the geometry is defined by the plane being vertical to the two counterstreaming electron populations ( referred as the yz plane )
對高能束流和電子迴流構成的雙流系統,建立冷等離子體流體模型,採用簡正模分析方法,分別考慮擾動波矢在平行於電流傳播方向的平面(記為xy平面)上和在垂直於電流傳播方向的平面(記為yz平面)上這兩種情況,推導了不穩定性的色散關系。
