  1. Namely, the electric field at the drain - side edge of the gate decreases with the increasing of negative charge density in the surface, so the breakdown voltage of gaas mesfet ' s will increase

    表面受主態的增多使表面負電荷密度增大,表面聚集的負電荷可以分散漏側柵邊緣處的電力線密度,減弱了柵靠漏一側的電場強度,擊穿電壓提高。
  2. 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

    本文主要討論光電反饋式靜電懸浮的理論問題.研究在靜電場作用下導電懸浮體的靜電感應機制和絕緣懸浮體的靜電極化機理,推導出懸浮體表面的感應電荷或極化電荷的計算公式,以及作用於懸浮體上的靜電懸浮力的計算公式,在理論上揭示了靜電力與電極電壓、電極面積、懸浮間距及懸浮體電學特性等因素之間的關系.結果表明,導電懸浮體表面的感應電荷量比絕緣懸浮體表面的極化電荷量多,因此前者所受的靜電懸浮力比後者大,但兩者均可實現靜電懸浮,這些結論與實驗結果完全符合.本文工作為實現靜電懸浮的光電反饋控制提供了理論依據
