still water level
解釋
靜水面-
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。 -
The water supplying industry is a naturally monopolizing one concerned people ' s life and state ' s future, running - water is an unrepeatable product and essential to people. covering over 20 years of reform and opening policy ' s carrying out, china ' s water supplying industry has made great progress. however there is still a long distance compared with people ' s needs and foreign advanced level, the water - supplying enterprises must carry out a further reform before a greater promotion occurs
供水行業是一個關繫到國計民生的自然壟斷行業，自來水是人們生產生活必不可少的，不可替代的產品，我國自來水行業經過二十多年的改革開放，取得了巨大的發展，但與人民群眾的要求和外國先進水平相比仍存在較大的差距，行業與供水企業都必須進行深入的改革，才能取得進一步的發展，國家對行業提出了以構築競爭性市場為出發點，以規范管理為基礎，以提高行業效率和服務質量為目標的改革思路。 -
Scientists are still uncertain about the role that the underground water plays in the movement of the so - called ice streams that may contribute to a rise in sea level
科學家還不能確定這些湖泊對冰流的移動起什麼作用，但是冰河可能影響到海平面的上升。 -
The main conclusions include : 1 ) water use level and water use efficiency in the yellow river region have been much improved than before, but are still in a lower level ; 2 ) water use level and water use efficiency are quite different in the different sub - regions of the yellow river region ; 3 ) agricultural water use index is high in this region, the main reasons lie both on the special climatic conditions, and the underlying surface situation, and on the extensive cultivation in this region
結果表明：黃河區用水水平和用水效率較以往有較大提高，但仍然還比較低；流域內用水水平和用水效率不平衡；農業用水指標偏高，既與其特殊的氣候條件和下墊面因素有關，也與該區較為普遍的粗放灌溉方式有關。
