  1. 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。
  2. But for real microfiltration, the distribution of shear stress on the membrane of the module with outside helical flow would have benefit to make smaller number of particles deposit on the membrane. ( 2 ) by means of orthogonal test and regression method, four new models, trans - membrane pressure model, flux model, trans - module pressure drop model, and efficiency model, were established, which roundly describe the performance of outside helical mf by depicting the flux, energy loss, and handling capacity simultaneously

    （ 2 ）採用正交回歸實驗，在無顆粒沉積的理想情況下，建立基於層流數值解的膜器跨膜壓力損失模型、過濾通量模型、過膜器的壓力損失模型和膜器過濾效率模型，首次從通量、能量損失及膜器對料液的處理能力等三個方面，更全面地對外旋流方式下的微濾過程進行了描述。
  3. This paper include the following parts. firstly the sine exciting - voltage is guaranteed by direct digital synthesize technology ; secondly the digital output of cos ( 9 ) and sin ( 9 ) are generated by microcontroller ; thirdly the two voltage signals which are the product of the two former signals gained by the multiplying d / a converter, being filtered and amplified, have constant frequency, and one amplitude has sine function relationship of with the input angle, and the other amplitude has cosine function relationship of with the input angle ; finally the two signals are acquired and analyzed by relative instrument and software

    主要由以下幾部分組成：用數字頻率合成技術（ dds ）產生正弦激勵電壓信號u _ msin （ t ） ；用單片機產生幅度的數字量輸出sin （ ）和cos （ ） ；用乘法型d a轉換器實現激勵電壓和幅度的乘積，並通過濾波器和功放后即得到頻率固定，幅值隨輸入角成正餘弦變化的電壓信號；最後用數據採集卡採集輸出信號，顯示波形並進行頻譜分析。
