  1. 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。
  2. The main issues of the research are put as following : firstly, with the international comparing of market sharing rate and trading competitive index, it was revealed that wheat in china has inferior international competitiveness with a bit rising during current years, however, which is still behind that of the main wheat export countries. secondly, after the international comparing of the main factors that affect the international competitiveness of wheat, it was discovered that chinese wheat has the obvious cost advantage on unit product, while because of the high circulation fee, it results in inferior advantage on the price ; low and unstable quality is another factor which leads to inferior wheat competitiveness ; the input of fertilizer and labor makes little impact on the productivity of chinese wheat, while the input of seeds, irrigation and machine makes a strong impact, so it should be more invested in seeds, irrigation and machine to reduce wheat ' s unit cost. the assistant industries of the wheat, such as breed, production materials and processing industries, have inferior international competitiveness and lagged development

    其次，通過對影響小麥國際競爭力的主要因素的國際比較發現：中國小麥單位產品生產成本具有明顯優勢，但由於較高的流通費用，導致在價格上不具有優勢；小麥質量較差、品質不穩定是導致中國小麥國際競爭力較低的主要因素；生產要素中化肥和勞動力投入對中國小麥生產力水平的影響程度較小，而種子、灌溉和機械投入對小麥生產力水平的的影響程度較大，因此小麥生產投入要以增加種子、灌溉和機械的投入為主，代替大量的化肥和勞動力投入，進一步降低小麥單位產品成本，增強中國小麥國際競爭力；中國小麥的上下游輔助產業（包括品種資源、生產資料和加工業）的國際競爭力較弱，發展較為滯后；中國小麥生產者的組織化程度較低嚴重製約了中國小麥質量的提高、流通費用的降低和加工業的發展；小麥生產經營活動本身的特點決定了在充分發揮市場機製作用的基礎上，必須通過政府的宏觀調控來克服其市場機制的失靈，保障市場機制有效運行，但通過國際比較研究發現：中國政府在生產者支持、市場體系建設和國際貿易政策上對小麥的支持水平較低，與提高中國小麥國際競爭力的要求有較大差距，尤其是較低的生產者支持水平和市場體系建設程度制約了中國小麥國際競爭力的提高。
  3. What form death may come in then does not matter, for the content is always the same - - our puny, painful life is ours only for a limited time before we inevitably must lose it

  4. Our results provided direct evidence that pf40 gene play a role in the tissue development, with knockout this gene the lateral buds were not visible. the plant hormones auxin and cytokinin appear to play a major role in controlling this process, therefore, the concertrition of auxin and cytokinin was measured, however, the concentration of the two hormone was variation a little in transgenic plants, but the ratio of the two was more than 5 fold in the pf40 gained function plant than that in wild type. furthermore the pf40 gene effected differentiation of the vascular bundles in different transgenic plants, results showed the pf40 could change both xylary fibers and vessel

    進一步的實驗發現pf40基因會影響植物側芽發育的早期，即pf40基因作用在側芽形成與發育的早期。對轉基因穀子的組織切片的分析還表明pf40基因引起不同形式的轉基因穀子的維管組織的發育的差異，轉化正義載體穀子的木質部變多，維管系統增多，而反義或干擾的轉基因穀子的木質部數量變少，木質部分化異常。從轉基因的結果可見pf40基因可以減弱植物的頂端優勢，這種作用是通過改變植物體內激素的含量實現的。

    在實踐方面，根據市場競爭力強弱可把這些農產品分成三類：第一類為競爭優勢產品，包括穀子、馬鈴薯、蘋果、核桃；第二類為競爭劣勢產品，包括小麥、棉花、大豆；第三類為中間類產品：包括玉米、高粱、蕎麥、裸燕麥、雜豆、葵花、梨、紅棗、蔬菜。這些產品在有些方面具有競爭優勢，有些方面又處于競爭劣勢。有些品種有競爭優勢，有些品種競爭劣勢。
