A novel method of electrostatic suspension was developed . this article briefly discusses the basic concept , schematic setup and optronic feedback system of the electrostatic suspension . when taking an aluminum plate and a compact disc ( cd ) as the suspended objects respectively , it is measured the electrostatic forces acting on the objects under different electrode voltages and different electrode - object gaps . the experimental results show that the electrostatic forces are sufficient to levitate both of the suspended objects , namely the electrostatic suspension method is practically feasible . compared to the conventional magnetic suspension , the significant characteristic of the electrostatic suspension is that it is capable of suspending most of the conductive and / or nonconductive , magnetic and / or nonmagnetic objects . therefore , this method can be widely applied to realize the electrostatic suspension and non - contact manipulation of the precision objects 本文提出光电反馈式静电悬浮的新方法，简要讨论静电悬浮的原理、装置及其光电反馈控制过程.采用铝片和cd光盘作为悬浮体，测定了不同静电电压和不同悬浮间距时的静电悬浮力，揭示了它们之间的相互关系.结果显示这两种悬浮体均可获得足够的静电悬浮力，证明了静电悬浮的可行性.静电悬浮方法的显著特点是既适用于导电体与非导电体的悬浮，又适用于磁性体与非磁性体的悬浮，克服了传统磁悬浮技术仅适用于磁性体的局限性，可广泛应用于精密元器件的悬浮与非接触无损操作

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
Concentrations of total suspended matter ( ctsm ) is unanimous with observational data and other scholars " researching results . the distribution of ctsm is higher along coast than other areas there is a tongue - like zone with high ctsm from north to southeast . the transport simulation result reveals that sm can spread to the okinawa trough for enough sea water mixing in winter . but in summer . sm can not traverse the big water barrier of kushino for different circulation character . this difference is probably related to the shifting n - s monsoon 悬浮体输送表明，在冬季，悬浮体除了在陆架上发生扩散外，由于海水的强烈混合作用和环流的季节性变化，部分中、底层悬浮体可扩散至冲绳海槽甚至西太平洋;在夏季，由于海水层化及夏季环流特征，悬浮体基本不能穿越黑潮这一水障，这一差异可能是由于季风和不同环流特征所引起的。
