Ir - ta - ti metal oxide coated titanium anodes of variable composition were prepared by thermal decomposition. their micro morphorogies and electrochemical properties were characterized by scanning electron microscope, open circuit potential, cyclic voltammetry, consumption rate measurements and accelerated life test. the sem results indicated that all coatings were of a porous and cracked - mud microstructure influenced greatly by the composition of coatings. the electrochemical measurements showed that the ir - ta - ti ternary oxide - coated anodes exhibited excellent electrochemical activity and electrochemical stability in both acidic media and seawater which were affected by the composition and microstructure of the coatings. owing to good corrosion resistance and low consumption rate in seawater, metal oxde coated anodes belong to insoluble material, and can be potentially applid in impressed current cathodic protection systems as an anode
採用熱分解方法在鈦基體上制備銥鉭鈦金屬氧化物陽極，用掃描電鏡對陽極塗層顯微形貌進行分析，通過強化電解壽命試驗、開路電位測試、消耗率試驗及循環伏安曲線研究了金屬氧化物陽極的電化學性能. sem分析結果表明銥鉭鈦金屬氧化物陽極塗層呈現多孔多裂紋形貌結構.隨陽極塗層組成不同，塗層顯微形貌表現出很大差異，這種差異直接影響陽極電化學性能.電化學性能試驗結果表明銥鉭鈦金屬氧化物陽極在酸性介質和海水中具有良好的電化學穩定性和電化學活性.此外，銥鉭鈦金屬氧化物陽極在海水中的消耗率很低，屬于不溶性的陽極材料，作為外加電流陰極保護用輔助陽極具有廣泛的應用前景 -
As is seem from above, if the natural ground is filled directly in high - fill side slope at liho airport. the entire stability of the side slope filled is good. there are n ' t global stability problems alongside with the hight of the strong - moderate weatheing mud shaly, but there are n ' t unstable location partly, alongside with overburden slipping
四川大學工程碩士專業學位論文通過以上分析得知，荔波機場高填方邊坡若直接在天然地基上填方，填方邊坡整體穩定性較好，場區不存在沿強一中風化泥頁巖的深部整體失穩問題。 -
Wld is a high - temperature anti - sloughing agent, which contains si and organic compound ion. by applying it with polymer drilling fluid in the high - temperature deep well and the well section of heaving mud shale, it can improve the stability of drilling fluid dramatically. and at the same time, it can deactivate the drill cuttings and the wall surface active point to greatly improve the property of rejection and anti - sloughing of the drilling fluid through the physical - chemical action occurring between the special group of molecule vs. drill cuttings and the wall surface
Wld高溫防塌劑是一種含有si元素和有機復合離子的抗高溫防塌劑，在高溫深井及易垮塌的泥頁巖井段配合聚合物鉆井液使用，不僅可以顯著改善鉆井液的穩定性，而且可以利用分子中的特種基團與鉆屑和井壁表面發生物理-化學作用，使鉆屑和井壁表面活性點鈍化而顯著提高鉆井液的抑制防塌能力。 -
Because of the merit of continuity, economical efficiency, reliability and high resolution, the well logging has shown its advantages, especially in some drilling engineering problem, such as the prediction of rock drillability, selecting the drill bit types, prediction of formation pressure, calculation the in - situ stress, evaluating the borehole walls stability and determining the reasonable mud density, and etc. aiming at the engineering accidents, for example the well spout, well leak, well collapse and the drill blocking during the drill engineering in the t formation in north - east of sichuan, some farther studies of formation pressure in feixianguan from well - logging information are presented in this dissertation
尤其是在巖石可鉆性預測與鉆頭選型、地層壓力預報、地應力計算以及井壁穩定性評價、泥漿密度安全窗確定等鉆井工程問題上。測井技術由於連續性、經濟性、可靠性及解析度高等特點，越來越多地顯示了其優越性。本文針對川東北部三疊系地層在鉆井過程中遇到的井噴、井漏、井塌和卡鉆等工程事故，主要對飛仙關組地層壓力的測井解釋方法作了大量的深入研究工作。 -
Abstract : in this paper the visco - elasticity constitution relationship of cyclic degradation describing offshore soft clay behaviors is studied. a method for quantitatively analyzing the stability of offshore soft soil sites under wave loading is developed by combining the relationship with water - mud multi - layer interface model. since the variation of nonlinear visco - elasticity parameters due to cyclic degradation of soft clay can be considered, the analytic results can reflect the changing process of soft clay under wave loading
文摘:本文研究了海洋軟土的循環弱化粘彈性本構關系，進而把它與波浪、水、土多層計算模型相結合，提出一種定量分析波浪作用下海洋軟土場地穩定性的方法.由於它考慮了軟土的循環弱化而導致的非線性粘彈性參數的變化，使分析結果能比較真實地反映波浪作用下海洋軟土層的變化過程
