在流体动力学近似下，考虑了在无外磁场的情况下，有限电子束对有限等离子体的激发。在束流的极限情况下，得到了不稳定条件和波的极限长度，并计算了束流-等离子体系统中激发振荡的增量。在等离子体和光束的半径基本上小于系统中的波长的情况下，激发条件和增量与无限等离子体中的无限光束的相应值最根本地不同。（auth）
In the hydrodynamic approximation, the excitation of a finite plasma by a finite electron beam in the absence of an external magnetic field is considered. In the limiting case of a beam the instability conditions and the limiting length of the waves are obtained, and the increments of the excited oscillations in the beam-plasma system are calculated. The excitation conditions and the increments differ most radically from the corresponding values for an unlimited beam in an unlimited plasma in the case when the radii of the plasma and the beam are substantially smaller than the wave-length in the system.
