| Abstract | 采用二维三分量静电粒子模拟程序研究了电子环束流对低轨道磁化等离子体中运行的航天器表面电侠和等离子体鞘层结构的影响,当有电子束流平行磁场入射时,航天器表面所带负电位的绝对值将增大型约电子束流的速度和密度的增加将使航天器表面负电位绝对值增加很快,与此同时等离子体鞘层的尺度也将增大型约形状将由尾部延伸的"泪滴"状变成向两侧展开的"机翼"状,当电子环束流以相对于磁场成一定角度斜入射时,由于磁场的约束作用, |
| Other Abstract | The effects of electron ring-beam on the satellite surface potential and plasma sheath in magnetized plasma of low earth orbit are studied by means of 2 1/2-D electrostatic code.The simulation results show that the satellite is charged nega-tively when there exists electron beam, and the increase of the density and veiocity r of electron beams increase the absolute value of satehit negative potential. When electron ring-beams are injected in an oblique angle with respected to the magnetic field, the efFects of electron rsr_g- ceavns decrease when the ouiique injection angle increases from 0°to 90°.the plasma.sheath beconmes wider when there is electron ring-beam mid its shapo changes from "tear drop" to "fan". |
