  1. Rate - distortion analysis and rate control play a key role in video coding and communication systems by providing the rate - distortion optimized compression performance, assuring the successful network transmission of the coded video data, and achieving the best visual quality at the receiver

    為了取得最優化的壓縮效率，確保編碼數據在通道成功傳輸，並在接收端獲得最佳的視頻質量，率失真優化和碼率控制技術具有重要的地位。
  2. Electromotor joins with high efficiency selected water pump, scm ( single chip micyoco ) control system commands water pump according to cooling water temperature which substitutes traditional strap - driving mechanism pump and forms tael - level intellectualized control cooling system combining with electromotion control of cooling fan. consequently it realizes that water pump and fan autoregulate with engine working status and assures t hat cooling water temperature keeps in the best range all the time and advances the reliability of engine working and realizes exact control of cooling water temperature in deed

    選用高效率水泵與電機聯接，改由單片機控制系統根據冷卻水溫控制水泵的工作，代替傳統的皮帶帶動的機械水泵，結合冷卻風扇的電動控制形成兩級智能化控制的冷卻系統，從而，實現了水泵和風扇轉速隨發動機工況變化的自動調節，真正實現了冷卻水溫的精確控制，保證了冷卻水溫始終保持在最佳范圍內，大量減少傳熱損失降低油耗，並提高了發動機工作的可靠性。
  3. Quantizing distortion efficiency

    量化失真效率
  4. In packet based wireless video communications, when best band distribution, not only source distortion should be considered, but also channel distortion caused by channel errors. the existing macroblock - layer rate control schemes calculates quantization parameters of all macroblocks ( mb ) in a frame in a raster scan order, and then encodes the mbs in the same order. actually, the quantization distortion is heavily dependent upon the coding order of mbs

    在基於包的無線視頻傳輸中，最佳帶寬分配時，不僅要考慮信源編碼失真，也要考慮由於通道差錯引起的通道失真；已有的宏塊層碼率控制演算法以矩陣掃描的順序計算一幀中所有宏塊的量化參數，事實上量化失真與宏塊的編碼順序有很大關系，改變宏塊的編碼順序，使復雜的宏塊分配到更多的比特數，顯然能大大提高編碼效率。
  5. As well as, using vector operation substitute scale operation in order to improve compression rate condition on keeping on distortion. by tool of vc + + simulate the result of research. finally, compared with jpeg, we can draw on a condition : using dct table substitute dct calculate and using vector operation substitute scale operation which can attain that is high compression rate and steady distortion

    其中，在dct變換中通過使用dct查詢標的方式代替dct常規變化，達到減少計算機乘除運算次數的目的；量化過程中通過使用矢量量化代替標量量化，達到在保證最小失真度的前提下提高壓縮比，並因此省略了jpeg壓縮中的熵編碼過程，簡化了壓縮過程，同時獲得最佳壓縮效率。
  6. When the input voltage varies from 40v to 60v and the output side varies from no load to rated resistance load, the output voltage will vary within 1. 3 % with the thd of less than 2 % and the highest efficiency of 86. 3 %

    當輸入電壓變化、輸出從空載變化到額定阻性時，輸出電壓變化量小於1 . 3 ，正弦輸出電壓波形失真度小於2 ，變換效率最高為86 . 3 ，額定阻性負載時效率為84 . 4 。
