“几乎”静电场中的悬浮
Levitation in an "almost" electrostatic field
摘要：
众所周知，带电粒子在纯静电场中不能处于稳定的平衡状态。在静磁场中，情况不同;因此，磁悬浮是可能的，而静电悬浮则不是。在本文中，出于与机械系统的类比，我们表明，除了一个小的振荡电场，否则静电配置导致稳定的不稳定的平衡点。因此，悬浮成为可能在一个“几乎静电”的领域。
英文摘要：
It is well known that a charged particle cannot be in stable equilibrium in a purely electrostatic field. The situation is different in a magnetostatic field; consequently, magnetic levitation is possible while electrostatic levitation is not. In this paper, motivated by an analogy with a mechanical system, we show that the addition of a small oscillating electrical field to an otherwise electrostatic configuration leads to the stabilisation of unstable equilibrium points. Therefore, levitation becomes possible in an "almost electrostatic" field.
