聚束陰極 的英文怎麼說
中文拼音 [jùshùyīnjí]
聚束陰極
英文
beam forming cathode-
To select a cylindrical plane cathode ; to design proper focus electrodes in order to control the formation of beam in methods of solving equations, electrobath and simulation aided by computer. to correct effects of anode hole and work out curves of designing guns ; to discuss plasma cathode guns at last
選用圓形平面陰極;設計恰當的聚束極形狀以控制電子束的成形,並使用解析法、電解槽法和數值方法三種方法進行設計;考慮陽孔效應對電子束傳輸的影響,修正陽孔效應,給出電子槍設計曲線;最後討論一下等離子體陰極電子槍。Beam forming cathode
聚束陰極電子束形成陰極2. to design an axial magnetic field. the cathode lies in 0. 4 - 0. 7 of peak value of the magnetic field and excursion channel in a uniform magnetic field to suppress space charge effects ; to design transition section between the gun and excursion channel in converse computation. 3
選擇電子槍陰極處于軸向聚焦磁場峰值的0 . 4 - 0 . 7倍處;漂移通道(互作用區)位於均勻軸向聚焦磁場中,以抑制電子束的空間電荷效應;使用反演算法設計電子槍和漂移通道之間的過渡區。Ca2 + ions from the reactants attended to be absorbed in the diffusion dilayer by the so3 - anion. calcium ions could compress the diffusion dilayer and reduce the aggregation number of aot molecular because of the higher charge density. the absorbance of ca2 + ions change of phase diagram of system and water core diameter
反應試劑溶液中的ca ~ ( 2 + )離子傾向于被吸附在aot極性頭基的- so _ 3 ~ -陰離子附近,壓縮了極性頭基水解產生的擴散雙電層,使得aot分子的聚集體變小,也使得處于束縛狀態的水分子數量減少。The structure of field emission triode is first simulated by magic. the tip height, tip position, tip curvature, gate aperture, and gate voltage are changed, to observe the emission current and the electron congregation
本課題首先採用magic軟體對三極體結構的尖錐場發射陰極進行了模擬計算,分別改變尖錐高度,錐尖位置,尖錐曲率半徑,柵極孔徑及柵極電壓,觀察陽極收集電流及電子束的會聚情況。分享友人
