  1. This machine is used for straight - line bevel cutting and bevel grinding and polishing for flat glass, in certain condition, it can be also used in bevel cuttig, bevel grinding and polishing for soft stone panel. the contrilling system adopts plc, it can accomplish automatic grinding cutting after entering processing parameter, convery speed adopts speed adjustment of fre quency conversion, direct drive of wheel head motor, all motions for joining in parameter adjustment completely adopt straight - rolling guide - track with front beam and wheel head lifting lntegrally. the transmission of input and output adopts synchronization tooth belt and photo - electricity switch positioning, and position limitation of two pass is much more reliable

    Sxm371pa型玻璃直線斜邊磨邊機是用於玻璃直線斜邊斜切，斜磨及光拋的專用設備，在一定條件下也可以用於軟石板材的斜切斜磨及拋光。控制系統採用plc控制。輸入加工參數后可自動完成磨削傳送速度採用變頻調速，磨頭電機直接傳動，所有加工參數調整運動副全部採用直線滾動導軌，前梁與磨頭整體升降，輸入輸出傳送採用同步形帶，光電開光定位，雙行程限位更安全可靠。
  2. But due to the difficulties of the theoretical calculation and the limitation of the technique of image display, only some two - dimensional graphs of electromagnetic field of a planar set of point charges or symmetrically and uniformly charged bodies, which ignores the boundary effect, are introduced in the present electromagnetics teaching materials, which brings much incovenience for the acquaintance of the electrostatic field

    然而，由於受理論計算和圖象顯示技術等因素的限制，目前的電磁學教材中，通常只能給出平面分佈的點電荷系或具有較強對稱性、忽略邊界效應的帶電體的電力線和等勢線的二維平面圖，這給靜電場分佈的感性認識帶來了一定不便。
  3. These topologies of inverters are composed of two bi - boost dc / dc converters, they are symmetry. so whole circuit turn into four - quadrant converters, we can control every power mosfet on or off. then we can get sine wave with direct current polarization at the left, at the same we also can get sine wave with direct current polarization phase contrast 180 compared of the left at the right

    這類逆變器由左右二個雙向boostdc / dc變換器構成，左右二邊是對稱的，所以整個電路構成了一個四象限變換器，我們可以恰當控制各功率管的開、關，使左邊的兩象限dc / dc變換器輸出一個帶直流偏置的正弦波，使右邊的兩象限dc / dc變換器輸出一個相差180度帶同樣直流偏置的正弦波形，這樣，負載zl上的電壓是左、右兩個dc / dc變換器電壓的差動輸出，正好可以消掉直流偏置，最終在負載r1上得到的就是正弦波。
  4. The iboc technology, as proposed by the us - based ibiquity digital corporation, is also known as hd radio. it is designed to operate in the existing am and fm bands by attaching digital data to the sideband of analogue signals. the attached segment can either be a separate radio channel or other data

    Iboc是美國ibiquity digital corporation所推廣的制式，又命名為hd radio ，它被設計成可以在現行的am和fm頻帶內運行，在模擬訊號的邊旁加上數碼訊號，它可以是電臺聲音廣播或是其它的數據，但由於頻寬的限制，最大約是200kbps系統設計雖然善用有限的頻譜，但技術上較為覆雜，目前正發展第二代產品。
  5. And, even participate in the kit cooperation that the large business enterprise produces system to produce, because of large business enterprise ’ s control of the need and the key technical, the small and medium business enterprise have to accept the buyer ’ s high price causing by the behavior of opportunism, which lead to their profit ability is low, being placed in tiny benefit or the edge of to the bad. so the small and medium business enterprise in the industry of dynamoelectric equipment are hard to get away from the predicament of the development in a long - term

    長期以來，由於許多中小型企業受資金匱乏、技術投入和技術開發力量不足，經營和生產者素質偏低、生產規模較小等因素的限制，市場能力難以獲得較快的提高;而且即使參與大型企業生產體系的配套協作生產，因大型企業對需求和關鍵技術的控制，導致中小型企業在分包市場上不得不接受買方機會主義行為所帶來的價格盤剝，盈利能力低下，處于微利或虧損的邊緣。所以，發電設備行業的中小型企業長期難以擺脫發展的困境。
