  • substitution : n. 1. 代，代用，代替，更替，置換。2. 【化學】取代；【數學】代換；代入；【法律】預定繼承人；【語法】詞的代用。adj. -al ,-ary adj.
  1. A linear programming method of vector loop used in the analysis of mechanism motion and its error was introduced, the possibility of using the sensitivity of kinematic analysis for error was analyzed, and it was proposed for the error analysis model of the mechanism to make equivalent substitution for the dimensional error with basic kinematic joint element ( kinematic pair ) and as well to implement the linear programming method of vector loop for error analysis within the adams

    摘要介紹機構運動分析與誤差分析的向量環路線性規劃法，分析運用運動分析靈敏度進行誤差分析的可能性，提出在機構誤差分析模型中用基本運動連接元素（運動副）對尺寸誤差進行等價替換，使誤差分析向量環路線性規劃法在adams中實現。
  2. ( 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。
  3. 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。
  4. The development of enterprise firstly depends on the birth and expansion of the transactions of element use right, which is the development of element market. the relationship between enterprise and market is not simply a kind of substitution but a sort of advance and dependence

    企業的發展首先必須有要素使用權交易的簽訂與擴大，這就是要素市場的發展，企業與市場並不是簡單的替代關系，企業與市場是相互促進、互為基礎的。
  5. During back substitution 2503 elements encounter a load applied to a degree of freedom that does not have any stiffness. the elements have been identified in element set warnelembacksubnostiffstep1inc1

    這個錯誤是什麼意思？如何解決？字面上看一個荷載加到一個沒有剛度的節點上怎麼解釋？謝謝！
  6. Recent development of element partial substitution to improve the characteristics of mg - ni - based hydrogen storage alloys

    系儲氫合金元素取代改性的研究進展
