  1. This paper carries on the 3d finite element structure analysis for power house monolith with a bulb turbine hydropower station located in the upstream of huang river as the carrier

    摘要以黃河上游擬建的某燈泡貫流式水電站為載體，對廠房壩段整體進行了三維有限元結構分析。
  2. ( 2 ) according to the forming model of the deep pull cracks, they can be divided into three classes pulled cracks -, pressed cracks and sheared cracks. ( 3 ) based on the two - dimensional and three - dimensional finite element methods. the following results can be affirmed : in the slope excavating process, the base surface will rebound in the direction of the excavating surface ' s excerior normal. the maximal displacements of the left and right bank are + 3. 6cm and + 2. 4cm ; the arch abutment will rebound in the direction of the river valley, the maximal displacements of the two bank are + 3. 5cm and + 2. 2cm ; the upstream and downstream surface will rebound in the direction of the normal direction. the maximal displacements are + 2. 1cm and + 1. 7cm. ( 4 ) the natural slope is stable

    （ 3 ）通過二維及三維有限元分析得知，左右岸拱肩槽邊坡在開挖過程中，開挖底面主要表現為朝開挖面外法線方向發生回彈，左右岸最大位移量分別為+ 3 . 6cm 、 + 2 . 4cm ；拱端面主要表現為向河谷方向發生側向回彈，左右岸最大位移量分別為+ 3 . 5cm 、 + 2 . 2cm ；上下游坡面主要表現為向臨空方向的回彈，左右岸最大位移量分別為+ 2 . 1cm 、 + 1 . 7cm ；開挖使巖體產生由卸荷回彈導致的傾倒拉裂現象。
  3. ( 3 ) on the basis of the deletion analysis, three substitution mutants ( ml : 6bp sequence upstream of gcc box m2 : gcc box and m3 : g box - like sequence ) by pcr were designed to isolate the essential ja - responsive element. transgenic tobacco plants containing promoter substitution constructs were generated by agrobacterium - rnqdiaied leaf transformation. loss - of - function experiment, using transient expression analysis of gus reporter genes, confirmed that gcc box act as an essential element to respond ja signaling in pdf1. 2 promoter

    （ 3 ）在缺失突變的基礎上，通過對gccbox及其相鄰的上下游六個堿基進行取代突變，將突變啟動子與gus構建融合基因，在煙草中受heja誘導的瞬時表達結果表明， h1和m3的突變對該啟動子應答ja信號的影響很小，而m2 （ gccbox的突變）則幾乎使該啟動子應答ja信號的功能完全喪失，所以gccbox是該啟動子中應答ja信號的必需元件。
  4. The clpg mutation is a a g substitution 32. 8 kb upstream of gtl2, which was later shown to be the only difference between the callipyge and wild - type chromosome in what is probably a long - range control element ( lrce )

    2002年， freking等人發現了一個位於gtl2基因上游32 . 8kb的a g的突變，這一突變位於一個新發現的轉錄本clpg1內部，它是callipyge羊和正常羊的唯一不同之處。
  5. The structure of the seed - specific promoter matches the characteristics of the promoter, having a basal promoter, initiator and upstream element

    種子特異性啟動子的結構符合類啟動子的特點，具有基本啟動子、起始子和上游元件。
  6. Extension of low k + treatment to 12 hours did not increase the binding sites or protein abundance either. among ros species, h2o2 was specifically involved in the up - regulation of na, k - atpase induced by low k. 96 base pairs of upstream of na, k - atpase subunit promoter was the key cis - element in transcriptional regulation of promoter activity

    Ros對鈉鉀atp酶亞基啟動子的刺激作用縮小至編碼區上游96堿基對，該序列包含多個潛在sp1轉錄因子結合位點，研究也表明sp1參與了低鉀對鈉鉀atp酶的調節作用。
