The main characters of the river - valley landforms are followed : the outstandingly longitudinal range - gorge landforms constitute the unique view of three parallel rivers ; the relative highness difference of the landform is great and the river valley cut deeply ; the formation and evolution of the river - valley landforms are obviously controlled by the geological structure ; the landforms types and the various characters of the landforms combination in the drainage area are prominent ; the geological environment has relatively strong frangibility ; the branches riverhead of the river - valley mostly come from high mountains and lakes, and the river - valleys of the branches along the banks have disproportional distribution
其河谷地貌的主要特徵有：突出的縱向嶺谷地貌，構成了少有的三江併流奇觀；地貌相對高差大，河谷深切；河谷地貌形成演化發育明顯受地質構造控制；流域范圍內地貌類型和地貌組合多樣化特徵突出；地質地貌環境具有較強烈的生態脆弱性；河谷支流水源多發源於高山湖泊，兩岸支流河谷分佈不均衡。 -
Xh rubber slowly - closing cut - off vavle is a new water supply and drainage vavle with full rubber structure, duck - mouthed appearance and functions or positive flow - in and reserve cut - off. according to thrust analysis and calculation as well as different operation mechanism and different rubber products by special processing. all will be open at weak hydraulic pressure is higher, the vavle gate will open more greatly and the water flow is greater. at reserve operation, the vavle gate closes naturally and seals tightly cut - off vavle ; the back pressure is higher, the vavle gate closes more tightly and the seal effect is better. it is used widely in various drainage exit to prevent from pouring backwards and flowing backwards in city planning, water conservancy and sewage disposal etc. it is the ideal productto replace flap vavle
Xf型橡膠緩閉逆止閥是一種全橡膠結構外形呈「鴨嘴狀」 ，具有「正向流入反向逆止」功能的新型給排水閥門產品。它根據受力分析和受力計算，針對不同的工況，採用不同的設計機理，選用不同的橡膠配方，並按特殊工藝製作而成。正向工作時，水由進水口流入，微小的水壓，便能打開閥門，水壓越大，閥門開啟越大，水流量越大。 -
Making use of many layers composite technique and heat press technique to make artificial skull, through a series of performance testes ( including elongate performance, compress performance, curve performance, concussion performance, lay cut performance, concussion cut performance ), making use of drainage method to calculate its average density, which is 1. 25kg / m3, and combustion method to calculate its content of macromolecule, which is 57. 7 %
利用多層復合技術和模壓技術制備來的人工顱骨復合材料，通過對其一系列性能測試（包括拉伸性能、壓縮性能、彎曲性能、沖擊韌性、層間剪切強度和沖擊剪切強度等） ，證明了該復合材料具有良好的物理機械性能。採用排水法計算復合材料的平均密度為1 . 25kg m ~ 3 ，採用灼燒法計算復合材料的含膠量為57 . 7 ，證明該復合材料比強度較高。 -
Cut plane datum only illustrate recharge and drainage relationship of part areas of the river, even though we conclude qualitative conclusion through cut plane datum, but we must make further research from qualitative conclusion to quantum
剖面資料僅能說明局部河段補排關系，代表整個沖積平原河水與地下水關系有其局限性。灌區與河道地下水補排關系，盡管從剖面分析得到了定性結論，但從定性到定量還需進一步研究。
