自去磁
英文
self-demagnetization-
Yes, i m glad i went, and such a quaint dear cheeky baby, clifford, said connie. it s got hair just like spider - webs, and bright orange, and the oddest, cheekiest, pale - blue china eyes. of course it s a girl, or it wouldn t be so bold, bolder than any little sir francis drake
「是的，我覺得很高興出去走一趟，克利福，那真是個可愛的孩子，這樣玲瓏而毫無忌憚」康妮說， 「她的頭發簡直象蜘蛛網，有著光耀的橙紅色，兩隻眼睛淡藍得象磁做的一樣，那奇妙而毫無忌憚自然呵，因為那是個女孩，否則不會這么大膽的。 」Abtd automatic bulk tape degausser
磁帶自動整體去磁電路Sbtd autonatic bulk tape degausser
磁帶自動整體去磁電路The zircondri filin wtut rirconia wa prepared and the removing technology of the zirconia on the zirconium sdrices was obtalned. the methods of chemistry and magnetron sputtring plating were used in order to platc a palladium film, which is characteristic of self catalysis for hydrogen and the sole h - permselectivity on the clean rirconium sdrices prepared by the methods of electrochemitw and ( or ) high temperatur vacuum hydrgenization, which was firstly studied. the plating tedrilogy was obained and the surface modified zirconium membran was prepared
在利用電化學法和真空高溫除氧加氫法去除了鋯表面氧化膜的基礎上，分別採用化學法、磁控濺射法兩種鍍膜技術在其表面上鍍上了一層對氫具有自催化分解、唯一選擇滲透性的金屬鈀膜，首次獲得了鋯基材膜表面上鍍鈀的制備工藝，成功制備了鋯表面改性選擇滲氫膜。Abstract : a two - pole axially - laminated anisotropic ( ala ) rotor reluctance motor, with a high saliency ratio, is de - veloped. based on it, the performance characte istics of the motors are investigated with open - loop operation. it is proposed that an intensive oscillation occurs at low speed, corresponding to the frequency supplied a little greater than the natural one of the system
文摘:研製了一臺高凸極比的兩極ala轉子磁阻同步電動機，實驗研究了電機的開環運行特性，研究結果表明電機開環運行時存在一個比較嚴重的低頻振蕩，這個振蕩發生在電機電源頻率略大於電機的自然頻率后的某一頻段，且會導致電機失去同步2, the single - phase electrical strict sense, the main winding of the magnetic field is generated directly to the pulse magnetic field rather than straight to rotary magnetic field is not a moment ; namely : supply of electrical equipment not own
2嚴格意義上的單相電機，其主繞組所產生的磁場是直來直去的脈動磁場而非旋轉磁場，是沒有啟動力矩的即：通電后電機不會自己轉動。Simulations for these two conditions prove validity of theoretical analysis. on the basis of this scheme, a new speed adjustment strategy about vector control of doubly fed motor based on rotor current vector fixing is given. it introduces the closed - loop of stator excitation current to the system, which increases two adjustment channels : speed and excitation adjustment
經理論分析可知，該方案中，由於轉子電流與磁鏈無法實現完全解耦，故僅在亞同步工況下有效，在超同步時則會因為調速系統不能自動校正轉子磁鏈幅值變化引起的橫向電流而使系統失去控制，無法達到穩定狀態。Wavelet transform domain adaptive filtering algorithm for removing the seamless pipe noise contained in the magnetic flux leakage data
去除漏磁數據中無縫管道噪聲的小波域自適應濾波演算法In the design of real - time control system, the paper takes three - phase full - bridge mosfet inverter as the real - time control main circuit, and adopts a control scheme with 120 ? switching mode combined with half - bridge pulse width modulation ( pwm ), which would avoid straightthrough short of a certain bridge. phase current is detected by single current sensor ; three - phase position signals generated by position sensors could not only supply commutation information for inverter, but also be used for speed detecting based on signals " period measurement, which makes the speed sensor unnecessary. the whole control system adopts speed and current dual closed - loop control strategy in order to construct a high performance rare - earth permanent magnetic brushless dc motor ( repm bldcm ) full - digital real - time control system
在實時控制系統的設計中，本文以三相全橋mosfet逆變電路作為實時控制主電路，採用120導通方式結合半橋pwm調制的控制方案，從而有效地避免了橋臂的直通短路；本文用單電流傳感器實現對相電流的檢測，來自位置傳感器的三相位置信號不僅為逆變電路提供換相信息，而且也用於基於信號周期測量的轉速檢測，這樣就省去了速度傳感器；系統採用的是速度、電流雙閉環控制策略，力求構建高性能的稀土永磁無刷直流電動機全數字實時控制系統。分享友人
