Zmd系列自吸磁力泵採用電機直聯式結構,由中間支架支撐,結構緊湊,拆卸維護方便,採用高性能磁性材料「釹鐵硼」製造內外磁體,隔離套採用進口非金屬材料,徹底消除了一般磁力泵具有的磁渦流損耗,可輸送高濃度,密度大於1 . 84 t mThe author excogitated a kind of appropriative mud jacking material which is made up of cement, sand, fly ash, admixture and water. this material which was developed on the basis of large amount of tests has the proprieties of good self - flowing density, high earlier strength, non - segregation, non - weepage and non - contractility. especially, the author aim at dealing with pumping mud and earlier maintained developed a kind of high flow grade material which can meet the requirement of mud jacking
本文研製了專用壓漿材料,採用水泥、砂、粉煤灰、外加劑和水混拌而成,通過大量實驗配製出的漿液具有自流淌密實性好、早期強度高、無離析、無泌水、無收縮的性能,特別是針對路面唧泥處理或預防性養護,板底脫空量較小,研製出高流動度材料,能滿足壓漿施工的需要。With the development of high power microwave tube, the theoretical and experiment investigation of the high performance cathode have been conducted. the research work includes how to prepare the high performance cathode and the effect of the based metal on the cathode emission, the measurement of the inner and surface fine structures of the cathode, the discussion of emission mechanism of thermionic cathode. after a lot of experiment, we finally determined the cathode preparation with an excellent emission
為了適應大功率微波管的發展,本文展開了對高性能(大電流密度、長壽命)陰極的研究,研究工作包括陰極制備工藝、鋇鎢陰極基金屬對陰極發射性能影響、以及鋇鎢陰極基底內部結構無損檢測及表面形貌檢測、鋇鎢陰極發射機理探討及應用四個方面的實驗和理論的研究。The experimental results showed that firstly, the distribution of resistiveity, mobility, carrier concentration, epd and ab - epd in gaas substrate was not uniform ; secondly, the distribution of electrical parameters depended on that of epd and ab - epd ; thirdly, mesfet devices performance correlated with ab microdefects ; last, as shown by pl mapping results, it is substrate with better parameters quality that could provide more chance to fabricate good mesfet devices
實驗結果表明, lecsi - gaas的電阻率、遷移率、載流子濃度、位錯密度和ab微缺陷分佈都不是均勻的,且電參數的分佈與ab - epd 、位錯密度分佈有關。製作的mesfet器件的性能參數分佈與ab微缺陷有明顯聯系。從plmapping測量結果可以看出材料的襯底參數好,則pl譜的強度高, pl譜均勻性也好,器件參數也好,就有可能製作出良好的器件與電路。Electronic commerce, as a result of high speed development in communications, network and information technology, combines the enterprise, supplier and customer of traditionary commerce firmly with its powerful data information and efficient corresponding network, which can press manufacture close to consumption, and can reduce transactiona ! cost of material flow, fund flow and information flow. so we say electronic commerce is a thoroughly commerce innovatory mode, it is a direction of trade in the future
電子商務作為通信、網路和it技術高速度發展的結晶,它應用強大的數據信息和高效的通信網路把傳統商務的企業、供應商和客戶緊密聯系在一起,使生產和消費更為貼近,減低了物流、資金流以及信息流傳輸處理成本,是對傳統貿易方式的一次徹底變革,也是未來貿易發展的必要方向。The experiment results indicate that 90 % pressure drop is attributed to minor pressure drop in heat sink and these results are higher than the theoretical value. the thermal resistance will drop with the increasing of pumping work and the extent of the drop will decrease when the pumping work reach some value. the maximal temperature difference between the heat - sink surface and the coolant will increase with the increasing of heat fluxes, as is same to the maximal temperature difference on the heat - sink surface
研究表明,在微射流熱沉中,熱沉總阻力主要是由局部阻力引起的,佔到熱沉總阻力的90 % ;微射流陣列冷卻熱沉熱阻隨泵功的增加而減小,但是當泵功增加到一定程度時,熱阻變化趨于平緩;熱沉散熱片底面溫度和溫差隨熱流密度增加而升高,但是溫差保持在一定范圍之內。分享友人
