( 2 ) this paper has firstly identified these genetic units on shore beach - shore face, longshore zone, longshore sands, erosional channel, leveed channel, turbidite lobes, turbidite sheet, slump, debris flow, density - modified grain flow etc ; at the same time, and points out that the lake of cretaceous is open - type fresh water lake
（ 2 ）首次系統確定濱灘-濱面、沿岸帶、沿岸沙壩、侵蝕水道、有堤水道、濁積葉狀體、席狀濁積、滑塌體、碎屑流、密度改正顆粒流等成因單元。同時指出白堊紀湖泊為開放型淡水湖。 -
Takes several energy saving measures for air conditioning system, nick a large capacity centrifugal chillers working with variable frequency nil capacity chillers, variable frequency and variable flow control on secondary pump water systems, cooling tower for four - pipe water system in winter, fan - coil unit for commercial peripheral zones aid all - air systems for interior zones, variable frequency control on supply and exhaust air fain, enthalpy control on fresh air cooling in winter and intermediate season

The slick could reach the russian border as soon as sunday. it has already disrupted the normal flow of fresh water to millions of chinese who live near the river
這條污染帶最早可能在星期天到達俄羅斯邊界。這條污染帶已經打亂松花江沿岸幾百萬中國居民的正常供水。 -
After the implementation of water regulation, the river course in delta reaches the minimum ecological flux, and no flow interruption take place ; the runoff flowing into the sea and the transporting sediment increase ; the areas of fresh water wetland is also increased gradually ; species variety get instauration obviously
結果表明，黃河水量統一調度后，河口三角洲最小河道生態基流在非汛期基本得到滿足，斷流現象不再發生，徑流入海率和輸沙入海量有所增加，淡水濕地面積逐漸增多，物種多樣性明顯得到改善。 -
Upon completion of the extension to the tai tam reservoirs, the water supply problem was finally under control, particularly for supplies to central. however, supplies to sheung wan and the western district continued to be inadequate, due to inefficiency in the water transfer system. the connection between the tai tam water supply system, via bowen road and the western district, relied solely on a 10 - inch diameter water pipe. this restricted the flow of fresh water from the tai tam reservoirs to the western part of hong kong island
大潭水塘的擴建工程完成後，對紓緩港島東區及中區的食水供應有很大的幫助，但卻未能完全解決西環及上環一帶的食水短缺問題，因從大潭供水系統抽調的淡水流至中環后，一直只依靠一條直徑10寸的輸水管連接寶雲通往西區，其輸水量並不足以供應整個西環及上環區，直至1929年，該區的居民仍主要依靠薄扶林的供水系統獲得淡水。 -
Workability - design of fresh concrete was studied from rheology aspect. mortar slump flow test was further developed to evaluate properties of water - reducers and compatibility between cement and water - reducer for mortar. a method for measuring water absorbed by coarse aggregate in fresh concrete was put forward
從流變學角度對新拌混凝土工作性進行了以下研究：進一步完善了砂漿坍落擴展度試驗方法，用於測評砂漿中減水劑飽和摻量及水泥對外加劑的適應性。 -
Measures for further developing concrete mix design were presented based on above work. for example, adopts pfca as an index in designing durability of concrete, uses mortar slump flow test to select cements and water - reducers and to measure saturation dosage of water - reducer in mortar and then determine optimum dosage of it in concrete, uses bar - slump test to determine stability and fluidity of fresh concrete, and consequently, the workability of high fluidity and high stability concrete such as pumped or self - compacting concrete can be designed by adopting proper cfvm determined in terms of rheological properties of designed mortar measured with cone - based rheometer
如採用粗集料破碎率作為耐久性設計的一個指標；採用砂漿坍落擴展度試驗選擇水泥和減水劑，確定砂漿中減水劑的飽和摻量，並通過上述數學模計算混凝土中減水劑的飽和摻量，以此為參照確定最佳摻量；採用障礙坍落度試驗確混凝土的穩定性和流動性，結合由漏斗式砂漿流變儀測定的砂漿流變性能確定合理的砂漿填充系數，從而實現對高流動性高穩定性要求的混凝土（如泵送和免振自密實等）的工作性設計。
