摘要

考虑了一个描述电子在带虚阴极二极管内流动的流体动力学方程组。通过在运动方程中引入相应的制动力来考虑碰撞。描述了电子流的定态。在线性近似下，考虑电子碰撞的有效频率，得到了虚阴极二极管中电子振荡频率的计算公式。得到了由于碰撞而引起的振荡衰减的表达式。

EFFECT OF ELECTRON COLLISIONS WITH RESIDUAL NEUTRAL GAS ON CHARACTERISTIC OSCILLATION FREQUENCIES IN SYSTEMS OF ELECTRON FLOWS WITH A VIRTUAL CATHODE

A system of the hydrodynamic equations describing the electron flows in a diode with a virtual cathode is considered. Collisions are considered by introducing the corresponding braking force into the equations of motion. The stationary states of the electron flows are described. In a linear approximation, formulas are obtained for the frequencies of electron oscillations in a diode with a virtual cathode, considering the effective frequency of electron collisions. The expression for the decrement of oscillations due to the presence of collisions is obtained.
