  1. This paper unfolds engineering disposition and theoretical research of negative temperature high performance concrete ( nthpc ) with the damage of many factors motivation, the project background based on qing - zang railway engineering, which is one of four - emphasized engineering during the tenth five - plan. due to the difference of environment of construction and service between nthpc and ordinary concrete, and therefore durability of nthpc is required to higher level. at a first, nthpc must avoid frozen damage at early age and possess anti - freezing property at later period, in order to meet engineering practicable application need, and this are two emphasized and difficult problems, as for nthpc ; by means of mechanism analysis about deicing - agent ingredient and anti - freezing at early period, adopting composite technique routine of mineral addition + anti - freezing element + water - reducer4 - air - entraining + anti - erosion of steel component etc, based on orthogonal experimental approach, fd - 1 composite functional admixtu re was manufactured, which has more property and orientation on qing - zang railway

    負溫混凝土由於和普通混凝土在施工環境及服役環境上存在的差異，因此表現為比普通混凝土更為較高的耐久性要求；負溫混凝土首先要避免早期的凍害以及具備長期抗凍性能，才能夠滿足工程實際應用的要求，這也是負溫混凝土必須解決的兩大技術關鍵；通過對目前常用防凍劑組分作用機理的分析研究及混凝土早期防凍機理探討，採用礦物外加劑+防凍組分+高效減水劑+引氣+阻銹組分功能復合的技術路線，通過正交試驗設計復配了適應青藏鐵路工程要求的專用多功能復合型外加劑fd - 1 ；並在此基礎上配製不同等級負溫高性能混凝土，開展一系列包括硫酸鹽侵蝕、氯離子滲透、抗凍融循環、收縮及耐磨性等耐久性能研究；通過對fd - 1組分和摻量的調整，優化負溫混凝土在施工特性、力學指標和耐久性三個方面的兼容、協調性。
  2. 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
