The effort of manganese removal was studied and the kinetics of manganese removal was tried to establish. the factors of dissolved oxygen concentration, fe2 + concentration, ph, p concentration and closing of the filter were studied to evaluate their effort for biological manganese removal, and the correlation of residual manganese and oxidation - reduction potential was also discussed. as the iron content of water was high, experiment results showed that the reaction was zero order, as the iron content of water was low, the reaction was first order. the time needed for the cultivation of biological manganese removal was 60 70 days. the filter operated at the filtration rate of 8 10m / h, silica sand of effective size 0. 95 1. 25mm filled the filter to a depth of 1200mm
試驗結果表明，成熟后濾砂表面濾膜的x射線衍射圖譜與mno _ x ? 5h _ 2o （ x = 1 . 86 ）的x射線衍射圖譜一樣，濾膜成熟后的結構在進水物質不發生變化的情況下不發生變化;合適的碳磷比對生物除錳有明顯的促進作用，試驗條件下的投磷量不會對出水造成二次污染;生物除錳需要亞鐵的參與，亞鐵的存在除了能夠促進微生物分泌胞外酶並刺激其活性外，還通過鐵離子的變價傳遞電子，催化錳離子的氧化反應，從而促進對二價錳的降解。It has shown that a good agreement between acoustic emission and transpiration, and the ae signal is a good water stress index for irrigation control
試驗結果表明，作物在水脅迫下產生的聲發射信號與蒸騰量等水分指標的一致性較好，對水分虧缺反應敏感，是一個良好的灌水指標。With the very low water to cement ratio, rpc has ultra - high strength high ductility and low permeability. in this paper, the compressive strength of rpc can reach to a high point with the number approximately 135mpa. as illustrated from the study results, we can approve some fundamental conclusions : there are big effects on rpc with deferent kinds and properties of raw materials and deferent curing conditions ; stress - strain curve shows the process of destroy with rpc samples ; x - ray diffraction analysis indicates that heat treatment at temperatures 90 accelerate the hydration of rpc sharply, therefore, mechanical and microstructural properties of rpc are highly dependent on heat treatment ; it is believed that rpc materials have excellent resistance to chloride permeability ; during the heat treatment, the shrinkage of rpc developed quickly because of chemical reactions ; the rpc with slag mostly has the advantage of rpc without slag about resistance to solutions corrosion
研究結果表明：通過對rpc各組分摻量變化的研究，可以找到rpc的最優配合比；試件成型后的熱養護制度對rpc的性能影響巨大； rpc的抗壓應力?應變曲線可以反映出試件受破壞時微裂紋的擴展情況，剛纖維的摻入可以大幅改善rpc的韌性； rpc在成型后存在較大的收縮，而其中的化學收縮要遠遠大於乾燥收縮； rpc具有很強的抗氯離子滲透性能，漿體的密實度很高；通過x射線衍射實驗，可以發現rpc的膠凝體中ch晶體已經幾乎不存在，膠凝體主要由c - s - h凝膠和未水化水泥顆粒組成；在抗溶液侵蝕的實驗中，摻礦渣rpc的抗溶液侵蝕性能在絕大多數情況下要好於不摻礦渣試件，酸、堿溶液和浙江工業大學碩士學位論文摘要一些鹽溶液都會對rpc的結構產生侵蝕作用，但是機理各有不同。Nevertheless the system cannot fulfill the request of present satellite launch because of the out - of - date equipment, the low grade of technique application, the in - normative system interface, etc. consequently it is crucial to update the system to meet the following satellite launch campaigns
但當前整個系統存在著設備老化嚴重，技術應用水平不高，系統連接標準不統一等弊端，由此造成了整個效率低下，設備故障率偏高，運行不夠穩定等一系列問題，為了適應后續衛星發射試驗任務的需要，迫切要求對系統進行相應的改造。During the rapid development of navy proving ground on the se4a ldnd of undodr optical highspeed video recording device is asked to test new underwaer weapon launching on submarine and meet the demand of underwater observing in near distance. underwater weak light high speed video imaging system ( swg - l ) consists of one wat902h camera and two pci500 digital highspeed camera to accomolish imaging underwater object
隨著海上試驗靶場的發展，新型水下兵器試驗和水下實時觀測的需要，目前迫切需要一種專門應用於水下的光學高速攝像設備，在近距離內實現對水下武器發射實況進行記錄，以滿足對水下高速運動物體運動姿態的觀測要求。Experimental study on acoustic emission characteristics of rock concerning hydromechanical coupling
