  1. It is studied that the formation mechanism of taylor bubble and its control method in gas - liquid two - phase flow, which affects the pressure balance and mechanical driving efficiency in the flow of petroleum engineering. experiments show that the formation of taylor bubble in gas - liquid two - phase flow is due to the intensive congregation and amalgamation of small bubbles driven by void fraction waves and that the highly turbulent flow is able to restrain this formation. thus, the flow regime transition may be checked by increasing the flow turbulence and controlling the disturbed frequency

    對大管徑氣-液兩相流動中嚴重影響壓力平衡與機械驅動效率的段塞流生成機制和控制方法進行了研究,實驗證明段塞流的形成是由於空隙率波的大幅度增長使氣泡高度集中,並形成聚並所致。強湍流運動可以抑制taylor泡的形成。因此,通過強化湍流或控制擾動頻率可以對氣泡聚並起明顯的抑制作用。

  4. Sige simox : oxygen ions with high dose were implanted into sige grown directly on silicon substrate for the first time, and sige - oi novel structure was formed successfully with additional high temperature annealing ; it has been confirmed that oxygen implantation with 45kev, 3 1017cm - 2 and annealing at 12500c in ar + 5 % o2 for 5 hours, are fit for the formation of sige - oi structure ; ge loss during the high temperature annealing has been observed, which is originated from ge volatility and ge diffusion ; it has been proposed to use nanoporous layer induced by h + / he + implantation to surppress ge diffusion and to use surface oxidation to overcome the upper limit of sige simox. sige smart - cut : hydrogen ions were implanted into sige material and followed by high temperature process ( 4000c to 7000c ) ; blistering study was done and suggested the possibility of sige layer transfer by smart - cut technology ; it is concluded that the bubble formation is easier in sige than in si, and the strain in sige / si and the difference of binding energy in sige and in si could possibly contribute to this effect. behavior of sige / si implanted with hydrogen : gave a detailed study on sige implanted by beamline or phi hydrogen implantation ; it has been found that great strain is introduced into sige by hydrogen implantation and this strain could be alleviated by high temperature annealing ; both for conditional beamline implantation and piii hydrogen implantation, 600 is appropriate for the post - implantation treatment

    Sige - simox工藝方面:首次採用硅( 100 )襯底上直接外延的100nm厚sige的樣品中注入高劑量的o離子,通過退火處理成功制備了sige - oi新結構,即sige - simox工藝,證實了以45kev注入3 10 ~ ( 17 ) 7cm ~ ( - 2 )劑量的氧離子,隨后在氧化層的保護下經1250 , ar + 5 o _ 2氣氛的高溫退火( 5小時)過程,可以制備出sige - oi新型材料;實驗中觀察到退火過程中的ge損失現象,分析了其原因是ge揮發( ge通過表面氧化層以geo揮發性物質的形式進入退火氣氛)和ge擴散( ge穿過離子注入形成的氧化埋層而進入si襯底中) ,其中ge擴散是主要原因;根據實驗結果及實驗中出現的問題,對下一步工作提出兩個改進的方案:一是通過在si襯底中注入適量h ~ + / he ~ +形成納米孔層來阻斷ge擴散通路,二是可以通過控製表面氧化來調節安止額士淤丈撈要表面sige層中的ge組分,從而部分解決sige

  8. With a rapid expanding of banking credit on real estate industry since 1998, as long as the housing price soaring, there are a theoretical controversy on real estate bubble in china. at the present, our real estate industry depends deeply on credit funds, the bank credit supports our real estate to its full flourish, while accumulating substantial risk correspondingly. therefore, researching the relationship between bank credit behavior and real estate bubble is of great meaning to understand the formation mechanism of bubble and to take measures to guard against and to dissolve the risk of real estate bubble

    本文借鑒carey模型和herring & wachter模型來研究銀行信貸行為與房地產泡沫之間的關系,認為銀行提供的信貸資金是房地產價格的一個決定因素,銀行信貸擴張是造成房地產價格上漲直至泡沫形成的重要因素;房地產業的高收益率、銀行對風險評估的失敗是銀行信貸集中於房地產業的主要原因;運用行為金融學理論研究表明,房地產信貸市場存在著過度自信與羊群效應行為,這些行為使得銀行低估信貸集中於房地產業的風險,從而使得大量的信貸資金集中於房地產業。
