  1. The second, at the high frequency primary coil, when switch turn on with control signal ( the spwm pulse is modulated ), in the positive or negative semi - period of low frequency modulation signal, transformer coil with same direction voltage. the magnetic flux of transformer core will increase step by step. at the end, it leads to magnetic flux saturation

    二、在高頻變壓器原邊,當開關管接收控制信號脈沖列(經調制的spwm波列)導通時,在低頻調制信號的正負半周內,施加在變壓器繞組上的是同一方向的電壓,變壓器磁芯中的磁通可能將級進地逐漸增加,導致磁芯飽和,造成磁偏或單向磁化,導致低頻電信號放大失真或由於很大的磁化電流而無法正常工作。
  2. The numerical results indicate that the deformation within the solid inner core is very small. however, in the fluid outer core, the changes of the displacement with relatively low spherical harmonic degree ( n < 10 ) is very complicated via the radius, due to the resonance near the eigenfrequenies of the core long - period oscillations. while the spherical harmonic degree of the loading is larger than 10, the deformation and the gravitational perturbation in the core are very small, and the earth ' s deformation response is dominantly represented as the radial displacement in the elastic mantle

    研究了地球在日月引潮力和表面荷作用下的形變特徵,數值計算結果表明,在固體內核中的形變很小,由於在長期核模本徵頻率附近的共振,液核中低階( n 10 )位移隨徑的變化非常復雜,當荷階數超過10時,地核中的形變和擾動位都很小,地球的響應主要表現為彈性地幔中的徑向位移,且隨深度增加急劇減弱,地表荷love數與信號頻率的依賴關系很弱,給出了體潮love數計算的一種有效的近似處理方案。
  3. The capacitor has advantages of low dissipation, high insulation resistance, good self - healing character, and steady electricity performance, anti - striking current, strong over - carrying capacity, etc. it is assembled sith inner hidden discharge resistance. it is applied in high or low pressure sodium lamp and mercury - arc lamp for the help of power factor compensation

    斷開電流允許時間:在0 . 5秒內的8個波前跳閘絕緣電壓ul1699第59節:線路與載之間1000v , 1分鐘
  4. The electro - hydraulic load simulator of fin stabilizer is physical half - objective simulative system. its function is to simulate, under laboratory conditions, different kinds of hydrodynamic force exerted on the fin stabilizer so as to detect technical performance index of the driving system of fin stabilizer. thus the classical self - destructing all - objective experiment will be converted to half - objective forecasting experiment in laboratory to achieve the aims such as shortening lead time, saving developing funds, enhancing reliability and success proportion

    減搖鰭電液載模擬臺是一種實物物理模擬系統,其功能是在實驗室的條件下,模擬船舶航行過程中減搖鰭所受的海浪水動力載荷譜,從而檢測減搖鰭驅動系統的技術性能指標,將經典的自破壞全實物實驗轉化為在實驗室條件下的實物預測性實驗,以達到縮短研製期、節約研製經費、提高可靠性和成功率的目的。
