  1. Linear induction motor is an important kind of machines which have some merits such as simple structure, low cost, durability, convenience for maintenance etc. the subject of this thesis is to study a big circular ring linear induction motor, and the major works in this thesis are summarized as follows : ( 1 ) considering the effects of the finite length of primary core, one - dimension analytical solution for the air gap field is cited in this paper. based on it, the single layer winding magnetic field is studied. considering whole - pitched and short - pitched winding configuration with odd poles and half - fulled slots in both ends, the double - layer winding magnetic field is analyzed, respectively

    本文對大圓環感應電機進行了深入細致研究,內容包括: ( 1 )本文採用有限長行面電流作用於有限長鐵芯上的模型,引用了氣隙磁場一維解,研究了單層繞組磁場,奇數半填槽雙層繞組在採用整距和短距時磁場的分析、比較,簡單介紹了二維解; ( 2 )用有限元軟體ansoft對大圓環感應電機空載氣隙磁場進行了靜態分析,並分析了結果; ( 3 )用軟體進行了額定電壓下的瞬態分析,得到了轉矩,位移,轉速隨時間變圖,利用單性霍爾元件測定轉速並與軟體計算結果進行了比較,採用等效電路法計算了堵轉時的最大電磁力並做實驗進行了驗證,由實驗測得了三相電流形,並與計算結果進行了比較,對其不對稱性進行了定性分析。
  2. However, df pre - processing is not required in a interferometer direction finder. it only makes use of the phase relations or differences of sensors disposed at different position. azimuth and elevation are caculated from the phase differences or displayed directly on a crt drived by the voltage or current from the phase differences

    干涉儀測向不必進行測向信號預處理而是接或間接求取在空間上分開的傳感器上感應電勢之間的相位關系,即干涉相位差,方位角或仰角是接由干涉相位差計算得到,或將兩基正交的天陣的干涉相位差轉為驅動電壓(電流)分別加到crt陰顯示器的垂偏轉圈和水平偏轉圈,模擬顯示出來方位,干涉儀測向為典型的相位測向方法。
  3. Srtio _ 3 ( sto ) thin films exhibit a large electric field dependence of dielectric permittivity. the microwave surface resistance of yba2cu3o7 - x ( ybco ) is much lower than that of the normal conductor. the typical value of rs for ybco epitaxial thin film is smaller than 1 m

    在低溫下, srtio _ 3 (簡寫為sto )薄膜具有強烈的非性介電性質,即:介電常數隨外加流電場變而變; yba2cu3o7 - x (簡寫為ybco )具有低的微表面電阻, rs ( 10ghz , 77k ) < 1m ,而且它們的晶體結構相似,晶格常數匹配以及學性質相容。
