  2. For the bldcm which has a pseudo - sinusoidal back - emf waveform, this dissertation presents a svpwm control method using six discrete position signals for minimizing the torque ripple. the main aspects for the implementation of this method are analyzed, including the initial orientation of the voltage vector, reasonable choice of the impedance angle and the advance commutation angle, and estimation of the successive rotor positions

    針對反電動勢類似正弦的準正弦波反電動勢無刷直流電動機，本文提出一種基於六個離散位置信號的自同步svpwm （電壓空間矢量法）控制方法，用以削弱電磁轉矩脈動，分析了實現這種方法的主要控制環節，包括起動時電壓空間矢量的初始定位，阻抗角與電流超前角的合理選擇以及連續轉子位置的估計等。
  3. Furthermore, this dissertation also gives a comprehensive analysis and comparison to the torque ripple factor, torque - current ratio and other aspects for pseudo - sinusoidal emf bldcm drived by 120 conduction mode, 180 conduction mode and self - synchronous svpwm mode respectively. the simulation and the experimental results indicate that self - synchronous svpwm method is more effective for minimizing the torque ripple without any expense of the torque - current ratio when the crest width of the back - emf waveform is less than 107 electrical angles

    對準正弦波反電動勢無刷直流電動機在120導通方式、 180導通方式和自同步svpwm三種控制方式下的轉矩脈動系數、轉矩電流比等方面進行了全面的分析與比較，模擬研究和實驗結果表明，當反電動勢的平頂寬度小於107電角時，採用自同步svpwm控制方法可以在不損失轉矩電流比的基礎上，更有效地抑制電磁轉矩脈動。
  4. In the united states, international treaties present at least four distinctive forms, and article vi, section ii of the us constitution adopts them wholesale as the supreme law of the land ; nevertheless, since 1829 the courts have come to distinguish the self - executing and non - self - executing treaties, but a large volume of cases and commentaries have controversy and confusion on the differential criteria, which has fallen into four categories in this article : intent, constitutionality, justiciability and private right of action

    首先， 《美國憲法》第六條第二款將在國內至少表現為四種不同形式的國際條約作為整體一攬子采納為全國最高的法律；但自從1829年，其司法實踐中開始區分自動執行與非自動執行兩種類型的條約，前者無須進一步採取立法或行政上的措施就能直接適用，後者反之。大量的案例和評論對於二者的區分標準充滿了爭論與困惑，本文將其分為意圖、合憲性、司法性和私人訴權四類並加以分析和評價。
  5. This paper proposes the occasional coupling synchronization scheme of the active - passive decomposition ( active - occasional coupling ). this scheme consists of synchronization and autonomous phases. in the former, the synchronization scheme is used to synchronize the drive and the response systems ; in the latter, small errors will lead to the two systems separated from each other and desynchronization. but if the synchronization phases are large enough, the full synchronization will be obtained. the synchronization condition is discussed theoretically. the spatiotemporal chaos in coupled map lattice system is achieved and the synchronization condition is given. moreover, the relation between the synchronization phases and the coupling strength is investigated numerically

    提出了離散系統中的主動-間隙耦合同步方法.該方法由同步相和自治相組成.在同步相，同步方案使得混沌系統趨于同步，而在自治相，兩系統間的誤差將迅速放大，導致失同步.但只要同步相足夠大，最終可實現系統的準確同步.還從理論上討論了同步條件，並利用該方法實現了耦合映象格子時空混沌系統中的混沌同步，給出了同步條件以及同步相與耦合強度的關系
  6. To develop the system to an automatic system, we have studied how to improve measurement precise by image processing after fast aiming. we use median filter to filtrate noise, use sobel arithmetic to detect the edge, and use kitchen - rosenfeld method to detect corners

    第一種方法著重研究了視頻採集和屏幕懸浮透明瞄準坐標系的同步顯示以及提高瞄準精度的途徑；第二種方法則著重研究快速瞄準后通過圖像處理技術自動獲得誤差補償數據。
  7. Second, the issue of approximate aggregation query on the data streams is discussed. meanwhile, the approximate query theories based on the histogram synopsis is proposed, and the autosuited histogram synopsis method and the histogram synopsis synchronization method are provided. third, the problem of predictive aggregate queries on the continuous data streams is researched, and a new predictive aggregate query method based on basic window synopsis and predictive equation is given

    本文圍繞連續數據流上的聚集查詢展開討論，首先針對數據流上的精確聚集查詢問題，提出3種改進的基於滑動窗口的精確聚集查詢演算法，這三種演算法可以在消耗很少內存的情況下提供高效準確的查詢結果;其次討論了連續數據流上的近似聚集查詢問題，給出了基於數據流滑動窗口的直方圖大綱理論，並提出了適用於滑動窗口的自適應直方圖大綱生成演算法和大綱同步策略;最後討論了連續數據流上的預測聚集查詢問題，提出了一種基於基本窗口及預測方程方法的預測聚集查詢演算法。
