  1. Based on features of natural electric potential in oxidation and reduction zones, it is held that the natural electric field method may determine the front line of the interlayer oxidation zone, and can hence infer the general position of the interlayer oxidation zone sandstone - type uranium deposit

    根據氧化帶與還原帶的自然電位變化特徵，利用自然電場法可以確定盆地層間氧化帶前鋒線，由此推測層間氧化帶砂巖型鈾礦大體空間位置。
  2. With the development of modern permanent magnet ( pm ) machine to high speed, high efficiency, high power density and micromation, the limitation of traditional rare earth pm machine is exhibited, such as higher ripple - free torque, higher losses, lower open - circuit magnetic field, etc. halbach motor, a new type permanent magnet motor, first proposed by american scholar klause halbach, has been studied very widely. halbach motor has higher magnetic field, usually as 1. 4 times as that of traditional rare earth permanent magnet machine, which attributes to higher power density

    Halbach永磁電機是由美國學者klausehalbach提出后一直被廣泛研究的一種新型永磁電機，和普通永磁電機相比其優越性有：氣隙磁密比一般永磁電機可增大40 ，從而可有效提高電機的功率密度；固有的正弦分佈磁場，可為電機設計和加工帶來便利，降低成本；自屏蔽效應，轉子可不再需要為磁路提供閉合迴路，這為轉子的選材提供了較大的空間。
  3. Ever since the movie camera moved out of the studio into the city space, film directors, production managers, cinematographers and art directors had realised the challenge of using public space

    自從電影拍攝由片場轉移到都市尋找拍攝領域后，空間和地域感成為很多導演製片攝影和美指的挑戰。
  4. In large rotating machinery using filmatic bearing ( turbogenerator, air compressor, etc. ) there is a potential trouble from impefect installation or running conditions, a metals " contact between rotors and shells. the trouble is usully called rubbing. the advantage of ae technologe in the rubbing diagnosis and early detection is showed. instead of classical ae characteristic parameters ( counts, amplitude, energy, duration and the other ones ) a new feature extraction by frequency analysis of ae envelop signals is discussed. both research of ae process and field experements indicate that periodic components in the envelop spectrum related to rotational speed increase evidently at the beginning of rubbing production, hence are highly sensitive to the rubbing fault diagnosis. according to the new design an acoustic emission equipment for the rubbing diagnosis named buaa ae testing system is developed and described

    汽輪發電機、空氣壓縮機等採用油膜支撐的大型轉動機械，由於安裝或運行中的原因，在轉子旋轉過程中，可能和器壁發生輕微的摩擦和碰擊，簡稱碰摩.聲發射技術在碰摩發生特別是故障早期診斷上有優越性.本系統的特點是沒有沿用傳統的計數、幅度、能量和持續時間等聲發射特性參數，而是在聲發射包絡信號的頻率分析中進行特徵提取.聲發射發生的過程分析和現場試驗都表明這種方法對碰摩檢測很敏感，在碰摩發生的起始階段，包絡譜中與轉速同步的周期性分量顯著增加.根據這種新的設計思想自行研製了buaa碰摩聲發射檢測儀並對此作了介紹
