  3. 1 m 0. 5, the phase - shifted angle 6 is controlled in term of sine law which makes the magnitude of resonant voltage track a reference sine voltage, and the resonant voltage is rectified, filtered, inverted and then the better sine - voltage output is obtained, theoretical analysis and experimental results show that for the resistive load and inductive load, the switches of leading leg of the phase - shift - controlled circuit are always turned on at zvs, and ones of lagging leg are turned on at zvs ( < 0 ) or turned off at zcs ( ( > 0 ), moreover, all switches in the low - frequency inverter are always turned on and off at zvs, the measured circuit efficiency for rated load reaches up to 88 %

    從功率單向流動角度出發，提出了一種lcc諧振型恆頻移相單相高頻鏈逆變電路拓撲，在調制系數0 . 1 m 0 . 5情況下，控制移相角按正弦規律變化，使諧振電壓脈沖列的幅值追蹤參考正弦電壓信號，經過整流、濾波、低頻逆變，從而獲得正弦度較好的輸出電壓。理論分析和實驗結果證明對于阻性負載或阻感性負載，移相全橋具有超前橋臂零電壓開通，滯后橋臂或者零電壓開通（ _ 0 ）或者零電流關斷（ _ 0 ）的軟開關特性，而低頻逆變器的各個開關均實現零電壓條件下的開通與關斷。
  4. Based on the resolving algorithm of continuous - layer method, the time order analyzing curves, acceleration curves and the response spectra of transfer function at the different points of the ground and at the same point on the different ground conditions are gained. it demonstrates that the responses of ground in x, y and z axial directions all change by time, and the obvious wave propagation appears in ground. for different observing points on the same ground condition, at more distant points from the load line, the less swings are found, that is to say, vibration possesses the obvious characteristic of attenuation

    基於分層法的解析演算法，得到了在不同點以及在同一點但不同地質條件下的時程分析曲線、加速度變化曲線和傳遞函數反應譜，結果表明，地基土在x 、 y 、 z三個方向的響應都是隨時間變化的，並且伴隨有明顯的波動現象產生；對于相同地質條件的不同觀察點，距離荷載作用線越遠的地方振幅越小，即振動具有明顯的衰減性。
  5. Carrierless amplitude and phase modulation has emerged as the de facto standard, having captured most of the nascent market to date

    無載波振幅和相位調制正在成為事實上的標準，迄今已佔了這個新生市場的大部分。
