本文試圖從膨脹劑不同摻量研究其對混凝土和砂漿主要性能的影響,進行了一系列宏觀力學性能試驗研究;利用差熱分析( dta ) 、掃描電子顯微鏡( sem )等分析手段對鈣礬石等水化產物的結晶和生成量、形貌特徵進行微觀分析;並採用復合方法摻加新型膨脹組分對硫鋁酸鹽類膨脹劑( uea )進行了改性試驗研究,根據多因素模糊綜合評價方法就各類膨脹劑的主要性能進行綜合評價,得出摻加新型膨脹組分pt的膨脹劑性能較優,取得了明顯的效果。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。The total rna was purified from the germ in the liquid by the guanidine isothiocyantehod method, then the total rna digested by dnase that had not rnase was used for rt - pcr. i change the magnesium ion dencity in the pcr system in order to optimize the pcr condition. at the end i selected the magnesium ion density as 1. 25 mm. the production of rt - pcr was inserted directionally into pgem ? z ( ampr ). the pgem ? z ( ampr ) was used to transform e coli jm109. i got a positive clone through culling and identificatin. the dna sequence inserted into pgem ? z ( ampr ) was sequenced and blasted with the cdna sequence of the # - mannanase mature peptide that got from genbank
分取誘導培養液中的菌體,用異硫氰酸胍法提取總rna ,總rna再經無rna酶的dna酶處理後用于rt ? pcr 。在pcr擴增目的基因時,通過優選擴增體系,使鎂離子濃度為1 . 25mm時rt ? pcr可順利地獲得目的基因,並能定向克隆到載體pgem ? 3z ( amp ~ r )中。用克隆載體轉化宿主大腸桿菌jm109 ,通過篩選獲取陽性克隆子,對陽性克隆子進行酶切與pcr鑒定,並對載體中插入的目的基因進行測序。All the results of present study show that the factors secreted by the adult oecs can promote pc12 cell differentiation and protect it from zn2 + insult. our results support the possibility that the adult oecs can release factors beneficial for neuronal survival and neurite outgrowth, as a part of the mechanism of enhancing cns regeneration following their transplantation
我們的結果表明aocm可誘導pc細胞分化,並對高濃度硫酸鋅損傷的pc細胞有保護作用,提示體內移植的成年oecs可通過分泌對神經元有益的因子促進神經元和軸突再生。There are 4 cysteins in the protein hbfgf, cysteins 78 and 96 are localized on the surface of hbfgf, whereas cystein 34 is completely buried and cystein 101 is partly buried within the folded peptide chain. so the cys78 and cys96 are especially prone to intramolecular disulphide - bond formation. we converted these two cysteins into serines
同時對於155個氨基酸的hbfgf來說,其34 、 78 、 96和101位的四個半胱氨酸的巰基有形成二硫鍵的可能,是造成二聚體或多聚體的主要原因,其中cys34隱藏在分子內部, cys101部分包埋在分子中; cys78和cys96暴露在蛋白質的表面,很容易因cys78和cys96的游離巰基氧化,在不同的分子間形成錯誤的二硫鍵。分享友人
