  1. According to the no - loading waveform deviation factor, the prototype conforms to the national design standard and practical needs in the engineering. more important, the high voltage is achieved. in the condition of considering core saturation and damping winding influence, the influence to powerformer of the no - loading tooth harmonic emf is smaller than conventional generator, and the waveform deviation factor of the former is smaller, too

    由求得的樣機空載電勢波形畸變可知,該樣機滿足國家設計和工程實用要求,更重要的是,實現了產生高壓的目的;考慮鐵心飽和、考慮阻尼繞組影響情況時,電力發生器與具有相同(除定子槽形)的傳統發電機相,空載齒諧波電勢對電力發生器的影響較小,前者的空載波形畸變較小。
  2. To illustrate the superiority of this type of transition, the author adapted the local normal mode ( lnm ) based on couple - mode theory to explain the coupling between two lowest order modes along the transition. for the two important parameters, propagation constants difference between the two modes apy and mode coupling coefficient cy, which denoting power coupling between lnms, the approximation expressions using structure parameters were worked out. then the author compared three typical different transitions according to the demanding of power coupling, at last concluded that the parabolic - type transition can transport the light in shortest length with lowest loss

    對于表徵局部模之間功耦合的兩個重要的參數_ ( ij ) (模式傳播常數差)和c _ ( ij ) (模式耦合系數) ,推導了用器件結構參數表達的近似公式,然後根據功耦合的需求,在常見的三種不同輪廓的過渡區之間進行了較,得出了拋物形輪廓過渡區能夠使光束在最短內以最低損耗通過波導的結論。
