  1. Sheath eddy current loss factor

    護套渦流損耗系數
  2. In simulations, all important phenomena, such as non - neutral sheath widening near cathode, cathode electron emitting, current channel migrating to the load side of the plasma, ion accelerating toward cathode and magnetic insulation of cathode emitting electrons etc, have been observed and depict the internal physics of this device. also presented is the influence of cathode emitted electrons on phenomena in the conduction processes of pegs. the simulation results show, without cathode emitted electrons, rapid magnetic field penetration takes place only in region near the cathode, with cathode emitted electrons, magnetic field penetration takes place in all plasma region

    診斷發現了陰極表面非中性鞘層的形成、陰極電子發射、電流通道的漂移、等離子體離子加速以及陰極電子磁隔離等物理現象，揭示了這一斷路器件的物理機制；分析了陰極電子對peos導通過程中的物理現象的影響，模擬結果顯示：忽略陰極電子作用，磁場滲透現象主要出現在陰極表面區域，考慮陰極電子作用，磁場滲透現象出現在整個等離子體區域。
  3. Calculation of the current rating of electric cables. part 1 : current rating equations 100 % load factor and calculation of losses. section 2 : sheath eddy current loss factors for two circuits in flat formation

    電纜載流量計算.第1部分：載流量公式100 %負荷因數和損耗計算.第2節：雙迴路平面排列電纜金屬套渦流損耗因數
  4. Those filaments self - organize in coaxial structures where the relativistic current in the center is surrounded by intense magnetic field and the return current sheath, and the magnetic field decreases abruptly to zero outside the relativistic current

    電流絲自組織形成同軸結構，束流被強磁場和迴流鞘層包圍，磁場在電流絲外迅速衰減到0 。
  5. First, we extended the liberman model of collisionless rf sheath. taking into account elastic collisions and charge - exchange collisions between ions and neutral particles, we established a self - consistent model describing the dynamics of rf sheath driven by a sinusoidal current source. the effects of collisions and rf - biased source power on the instantaneous thickness of the rf sheath and the sheath electric fields were studied

    首先將liberman的無碰撞射頻鞘層模型進行推廣，考慮了離子與中性粒子的電荷交換碰撞效應，建立了描述碰撞射頻等離子體鞘層動力學特性的自洽模型，研究了碰撞效應，射頻偏壓，電源參數等對射頻鞘層的瞬時厚度及電場分佈的影響。
