比特率減縮 的英文怎麼說
中文拼音 [bǐtèlǜjiǎnsuō]
比特率減縮
英文
bit rate reduction-
Through the experimental research, we think : the technological capacity of fiberglass asphalt macadam if weaker than asphalt macadam, however, if use elasticized capacity to solve blending technological problem. adjust the breed of fiber silk, extend its diameter, its paving capacity is still worth exploring, asphalt - rubber macadam structure lager have good deformed - become capacity and crazed - resistance capacity, small gap rate. good water - resistance capacity, good hot - stability and simple construction technology. therefore. pitch rubber spall is a good cover material which is suitable for the second class or lower whose asphalt pavement has split open because of fatigue. and is the good structural measure of preventing half - rigidity grass - roots unit shrink - rift reflecting. pave a thin layer of pitch rubber spall between asphalt - type pavement layer and half - rigidity basic level, although the cost of building is higher than paving togongbu in the middle, the construction technology, crazing - resistance and water - resistance are better than togongbu, not only could reduce greatly the reflex of half - rigidity grass - roots unit material, long then the use lifespan of pavement, but also it is possible to reduce suitably the thickness of asphalt mixture layer, though the cast of building in the early days becomes more, in the long - term opinion, it have fully important technological and economical significance
通過試驗研究認為：玻璃纖維瀝青碎石的技術性能不如瀝青碎石好，但路用彈性性能較好，如能解決拌和工藝問題，調整纖維絲的品種，增大其直徑，其路用性能仍值得探討，瀝青橡膠碎石結構層具有變形性能和抗裂性能良好，空隙率小，防水性能好，熱穩定性較好，施工工藝簡單的特點，因此，瀝青橡膠碎石是二級及二級以下公路因疲勞而開裂的瀝青路面的良好罩面材料，也是防止半剛性基層收縮裂縫反射的良好結構措施，在瀝青類路面面層和半剛性基層之間夾鋪瀝青橡膠碎石薄層，雖然造價比夾鋪土工布高，但其施工工藝，抗裂性能和防水性能均優于土工布，不僅可以大大減少半剛性基層材料的反射裂縫，延長路面使用壽命，而且可能適當減薄瀝青混合料面層的厚度，雖然初期造價有所增加，從長遠來看，具有十分重要的技術和經濟意義。This paper mainly discusses the design principles and chief techniques of a digital accessing system for power - line communication net ( plcn ). the technology of low bit rate speech compression high - speed modem based on plcn adaptive equalization to the channel anti - jamming and anti - fading are applied in this system. so speech tele - control data and tele - protection signals can be transmitted high quality in the band - limited channel
該系統綜合應用了低比特率語音信號壓縮編碼技術、基於電力通信網的高速調制解調技術、信號傳輸的通道自適應均衡技術和抗干擾、抗衰減技術，可在帶限通道中高質量的傳輸語音、遠動數據和遠方保護等信號，具有較高的整體性能。Besides the routine characteristics, xs series worm gear units adopts the helical gear - worm wheel type to make the structure more reasonable. the series not only has higher transmission efficiency and loading capability than those of single - stage worm wheel transmission, but also reduces space. moreover, under the close volume, the series can obtain higher transmission ratio and is more favorable for equipment setting
Xs系列蝸輪蝸桿減速機除具有常規特性外，該機還採用了斜-蝸輪形式，使結構更加合理化，它不僅改變了比單級蝸輪蝸桿傳動具有更高的傳動效率和承載能力，而且在結構布局上縮小了空間佔地面積，同時在相近體積條件下，能獲得更大傳動比，更有利於設備的配置，該機能與各種減變速機組合，滿足不同的使用要求。Some aspects of vertical twin screw compressor are compared with horizontal twin screw compressor : the axial bearing load of the vertical twin screw compressor is 57 % lower than horizontal twin screw compressor ; it also can increase 5 % capacity but it only occupied the 30 % area of horizontal twin screw compressor ; and it has more efficient oil separator as its special figure
並對立式螺桿製冷壓縮機與臥式螺桿製冷壓縮機進行了分析比較：立式螺桿壓縮機的軸向力比臥式壓縮機的軸向力減少57 % ；立式螺桿壓縮機的容積效率要比臥式壓縮機的容積效率高5 % ；由於油分的特殊環形設計，所以立式壓縮機的油分效果要比臥式壓縮機的油分效果好；而立式壓縮機佔地面積為臥式壓縮機的1 / 3 。For instance, arable land has decreased by 16. 7 thousand hectares at a speed of 3 % annually in recent years. structure of land use has changed basically. arable land, garden land, forest land and land for public transportation accounted for from 57. 4 %, 3. 1 %, 2. 8 % and 16. 9 % respectively in 1993 to 39 %, 7 %, 8. 3 % and 22. 3 % respectively now
城郊土地利用近10年來變化巨大：耕地面積大幅度縮減，近10年耕地減少量達到25萬多畝，年遞減率達3 ；土地利用結構發生根本性改變， 1993年耕地、園地、林地和工交建設用地的佔地比重從57 . 4 、 3 . 1 、 2 . 8 、 16 . 9改變為2002年的39 、 7 、 8 . 3 、 22 . 3 ；全區的生態服務價值出現較大增加態勢，這三方面成為該時期城郊土地變化的基本特徵。分享友人
