摘要

改进了Davis关于微米单颗粒在EDB（electrodynamic balance）中悬浮的两区理论，通过引入Oseen曳力公式和非齐次项，建立了振荡条件下颗粒完整的运动微分方程，并对其运动轨迹进行了数值模拟.从理论上证实了颗粒在EDB中存在稳定的阻尼振荡过渡区，给出了不同于Davis理论的三区状态图 (δ-β图)，从而构建了振荡条件下颗粒EDB研究的理论基础.这些理论结果的可靠性通过实验也得到了很好的验证.

Abstract

Based on the two-regime theory of Davis

a complete motion differential equation for a single oscillating microparticle in an electrodynamic balance (EDB) has been put forward by introducing Oseen’s formula and inhomogeneous term and solved numerically by using the classic Runge-Kutta method in this paper. The fact that there exists a transitional regime

in which the charged particle can be in steady damped oscillation

has firstly been demonstrated by theoretical method. By virtue of the simulated trajectories

a three-regime state curve (δ-β)

which is different from Davis theory

has been delineated and the theoretical foundation of EDB research on microparticle oscillation has further been built up.And the above-mentioned theoretical results have been verified experimentally hereby.
