带电尘埃粒子周围的热电子和亚超音速冷离子流动产生稳态尾流和德拜屏蔽场。这些线性静电场在二维平面或圆柱形几何中进行了研究。在较大（与德拜长度相比）下游坐标z的极限下进行渐近分析，得到与线性稳态响应函数的数值积分非常一致的解析尾流场。(C) 2000年美国物理研究所。[s1070 - 664 x(00) 01406 - 3]。
Hot electrons and sub- and supersonic flows of cold ions around a charged dust particle create steady state wake and Debye screening fields. These linear, electrostatic fields are studied in two-dimensional planar or cylindrical geometry. An asymptotic analysis in the limit of large (compared to Debye length) downstream coordinate z yields analytic wakefields that are in good agreement with numerical integrations of the linear, steady state response function.
