The high - power semiconductor quantum well ( qw ) laser is a kind of luminescence device with superior performance, it has longe - lived, low threshold current density, high efficiency, high luminosity and excellent monochromatic, coherence, directionality, etc. the high - power semiconductor laser is widely applied to the fields, such as military, industrial machining, communication, information processing, medical treatment, etc. the material ' s epitaxy is the foundation of the whole laser ' s fabricating, and it has important influence on the optics and electricity performance about the laser
大功率半導體量子阱激光器是一種性能優越的發光器件，具有壽命長、閾值電流密度低、效率高、亮度高以及良好的單色性、相干性、方向性等特點，廣泛應用於軍事、工業加工、通信及信息處理、醫療保健等領域。材料的外延生長是整個激光器器件製作的基礎，對器件的光學和電學性能有著重要的影響，生長不出優質的材料體系，獲得高性能的器件就無從談起，因此，材料的外延生長便成為了整個半導體激光器製作過程之中的重中之重。In accordance to the defects presented in using the chinese road asphalt technical standards to assess the asphalt performance as well as the facts that the shrp test equipment of usa can not be widely employed in china since its being very expensive, the shrp rheological concept is utilized in the research project to carry out the exploration of the rheological properties of modified and non - modified asphalt by using conventional tests such as penetration and ductility. the conclusions obtained by using the conventional test rheological index to assess asphalt performance are compared with those by using the shrp rheological index and their certain correlation are found
針對目前我國道路石油瀝青技術標準評價瀝青路用性能存在的種種缺陷，以及美國shrp試驗設備因其昂貴性而暫時無法在國內大量推廣應用這一事實，本課題試圖利用shrp流變思想，採用針入度、延度等常規試驗設備進行改性及非改性瀝青流變特性的研究，並將常規試驗流變指標評價瀝青路用性能的結論與shrp流變指標評價結論作比較，找出它們之間的相關關系，從而肯定了採用常規試驗設備進行瀝青流變特性及路用性能研究的有效性。The proposed md mesh - based motion coding methodis then combined with the pairwise correlating transform, and acomplete md video coding scheme is proposed. further measures are takento reduce the mismatch between the encoder and decoder that occurs whenonly one description is received and the decoder reconstruction isdifferent from the encoder. the performance of the proposed scheme isevaluated using computer simulations, and the results show, compared toreibman s md transform coding mdtc method, the proposed schemeachieves better redundancy rate distortion performance
數據重傳必然會引起延遲，因而在需要很短延遲的應用中是行不通的，如雙向無線通信同時在以廣播方式進行數據傳輸時也是行不通的當有大量突發錯誤時，糾錯碼如分組糾錯碼block code及卷積碼convolutional code無法在不產生額外延遲及需要額外運算的前提下對數據提供足夠的保護而錯誤掩蔽的性能則受接收到數據與丟失數據之間的殘留相關性大小的影響。It is not only the satisfactory substrate used for the epitaxy growth of infrared detector material hgcdte, but also attractive candidates for the manufacture of high quality x - ray or y - ray detectors, photoelectronic modulator, solar cell, and laser windows etc. no matter what the crystal is used as detectors or epitaxy substrate, it is of vital importanteto obtain high quality cdznte crystals with perfect surface
它不僅是生長紅外探測器材料hgcdte最理想的外延襯底，而且還被廣泛用於制備高性能x射線或射線探測器、光電調制器、太陽能電池和激光窗口等。獲得高性能、高質量的czt晶體是至關重要的。無論是作探測器還是作外延襯底等都要求它的表面質量要非常高，因為表面質量會直接影響到器件的性能。It is suggested that because the volcanic reservoir has very high heterogeneity, waterflooding process should not be adopted rashly in the early production period until obtaining experiences from clustered - well lest : infill drilling and adjustment during the period of early production may enhance producing extent, prolong water - free oil production period and improve performance response : a number of horizontal wells drilled during the mid - period of production may further increase the single well productivity and keep relatively long - term production stable and high
指出，由於火山巖儲集層非均質性極強，在火山巖油藏開發初期切不可貿然採用注水開發，應在實驗井組中取得經驗后，方可逐步推廣；開發初期，實施加密井調整措施，可提高儲集層動用程度，延長油藏無水開采期，改善開發效果；開發中期鉆一定數量的水平井，可進一步提高單井產能，使油藏保持較長期的穩產、高產。分享友人
