摘要通过引入等效电荷的概念，较好地处理了有极化电荷存在时象电荷的确定，给出了两种介质交界情况下的电象及电势问题的求解，从而说明用其解决问题的方便之处。 - This article solves some theoretical problems of electrostatic suspension based on optoelectronic feedback control . the mechanism of electrostatic induction of conductive suspended objects ( cso ) and electrostatic polarization of insulting suspended objects ( iso ) was theoretical discussed . the equations of charge density on the surface of suspended object caused by electrostatic field were developed . we further provided the equations describing the quantitative relationship of electrostatic forces verses the electrode voltages , the electrode area , the suspending gap , and the electric characteristic of suspended object . these equations show that the inducted surface charge density of cso is greater than the polarized surface charge density of iso , as a result , the electrostatic force acting on cso is larger than that acting on iso , as already proved by the experimental results of measured electrostatic forces . this work provided the theoretical equations and the mathematical models for effectively realizing the optoelectronic feedback control of electrostatic suspension
本文主要讨论光电反馈式静电悬浮的理论问题.研究在静电场作用下导电悬浮体的静电感应机制和绝缘悬浮体的静电极化机理，推导出悬浮体表面的感应电荷或极化电荷的计算公式，以及作用于悬浮体上的静电悬浮力的计算公式，在理论上揭示了静电力与电极电压、电极面积、悬浮间距及悬浮体电学特性等因素之间的关系.结果表明，导电悬浮体表面的感应电荷量比绝缘悬浮体表面的极化电荷量多，因此前者所受的静电悬浮力比后者大，但两者均可实现静电悬浮，这些结论与实验结果完全符合.本文工作为实现静电悬浮的光电反馈控制提供了理论依据 - In the case of dipole model , it gets the precision distribution of the electric field of the inside and outside of the particle by solving the laplace equation . the influences of the separation distance of the particles on the shear yield stress are investigated . and the result of the laplace is also contrasted with the result of the finite element by ansys software
