electron focusing 中文意思是什麼
electron focusing
解釋
電子聚焦-
The propagation of ultrashort laser pulse in air is analyzed with mechanics analogy by considering kerr effects and free electron defocusing. the equation describing the evolution of the laser spot is derived. it is shown that long distance focusing requires large initial beam and the propagation distance is very sensitive to the initial divergence angle of the laser beam
考慮多光子電離效應和光學kerr效應，首次利用力學類比的方法研究了超短脈沖激光在電離氣體中的傳輸，詳細分析了傳輸距離與激光初始光斑、初始發散角以及激光功率的關系，提出了實現長距離傳輸的條件。 -
The basic model about a novel plane yoke and focusing performances when electron beam is making a large angle deflection are discussed
摘要討論了新穎的平面形偏轉線圈的基本結構模式及其在電子束大角度偏轉時所具有的聚焦特性。 -
