Pulased mode of inverted - magnetron cold - cathode gauge
一種反磁控冷陰極真空規的脈沖操作模式The needle of understanding will yet point steadfast and unwavering to the distinct pole of truth
理智的磁針將永遠指向遠處真理的磁極。A filtered cathode vacuum arc deposition apparatus with a filtering duct working as second anode
過濾管道作為第二陽極的磁過濾陰極真空弧沉積系統For an actual planetwide polarity reversal to occur, such a reversed flux patch would grow and engulf the entire polar region ; at the same time, a similar change in overall regional magnetic polarity would take place near the other geographic pole
如果整個行星的磁極要真的反轉,反向通量斑塊需擴大到涵蓋整個極區;同時,另一個地理極點附近也會發生類似的區域極性全面變化。Analysis of static magnetic field of an iron style bipolar axial magnetic field vacuum interrupter by 3d finite element method
鐵芯式兩極縱磁真空滅弧室三維靜磁場有限元分析General model c38 dc meters are portable taut - band suspended moving coil instruments with light - spot indication. the meters have the feature of extremely high in sensitity and small in consumpition being particularly suitable to be used for measuring weak electric quantity on dc circututs, also for testing the static paramenters of transistors as well for measuring the output of millivolt values of zhermocouple in the vacuun furnaces ( or hydrogen furnaces )
C38型直流電表是磁電系張絲支承光點指示可攜式電表儀表具有極高的靈敏度,功耗小,特別適合弱電量直流電路測量及晶體管靜態參數測試用以及用做真空爐(或氧氣爐)中測量熱電偶的輸出毫伏值In the work, mid - frequency pulse magnetron sputtering is used to prepare znoral thin films used as the back reflector of the thin silicon films solar cells. the best techological condition was obtained by optimizing the preparing conditions, ( var is decided by the deposition rate, target voltage : 265v, gas pressure : 0. 6pa, the high base vacuum is expected
本文採用中頻脈沖磁控濺射法,通過優化zno : al薄膜的制備工藝,如靶電壓、本底真空度、工作氣壓、襯底溫度、 o _ 2 ar ,得到可用於硅薄膜太陽能電池背電極的zno : al薄膜。The core - mantle boundary is the closest researchers can get to the much more intense and complicated magnetic field that exists within the core, where magnetic fluctuations actually originate ; strong electric currents in the core prevent direct measurements of the magnetic field there
地核內具有更為劇烈、復雜的磁場,而且也是磁場變動的真正發源處,但是研究人員可推算的極限是在地核?地函交界處;因為地核內的電流極強,因此無法直接測量內部的磁場。A number of epidemiological studies have reported an association between human cancers and various surrogate measures of power frequency electromagnetic fields ( pf - emf ), but the epidemiological studies done in the past 20 years as a whole showed no persuasive evidence on the causal link of interest mainly because of methodological flaws, in particular inadequate exposure assessment and scarcity of exposure parameters, if any, truly associated with cancer
摘要累積超過二十年的時問,雖有許多流行病學研究發現,極低頻電磁場與人類癌癥發生有關,但整體流行病學研究仍未能提供充分證據說明極低頻電磁場與人類癌癥之間是否具有因果關系;其中最主要的原因是,流行病學研究所使用的電磁場暴露評估方法並不完善,並且無法確定真正與癌癥相關的暴露參數。It can get the information of the objects in its supervised water area by collecting the reflected electromagnetic wave. because the raw radar video represents the real condition of the supervised water area, it is an important information resource for vts centers and maritime administrative offices to get the evidence on the spot
雷達利用電磁波反射原理收集監測海域內的物體回波信息,雷達原始視頻數據實時動態地反映了海域內的真實情況,因此對于交通管制和海事取證具有極其重要的作用。分享友人
