等價變換
  • equivalence : n. 1. 均等，相等，相當。2. 【化學】等價，化合價相當；當量。3. 等值；等量。4. （語詞的）同義；同類。5. 【數學】等勢；等效。6. 【地質學；地理學】等時代。
  • transformation : n 轉變，變化；變形；【生物學】（尤指昆蟲的）轉化，變態，改造，改革；變質；【數學】變換；【電學】...
  1. Then we in - vest gate seiberg - witten map, which defines the equivalence relation of the gauge symmetries in different spaces. we also analyse the u ( l ) gauge electromagnetic field in noncommutative space. finally we discuss the ambiguities of seiberg - witten map, and find although that some part of the ambiguities can be absorbed by gauge transformation and hence negligible, the existence of the matter field makes some other parts difficult to be absorbed by gauge transformation or field redefinition

    然後利用seiberg - witten映射，我們研究了不同空間的規范對稱性的等價問題，並對非對易空間的電磁場進行了微擾分析，最後我們對seiberg - witten映射的松動進行了討論，研究發現這些松動中的一部分可以由規范變換吸收因而是可以忽略的，由於物質場的存在，另外一部分很難用規范變換和場的重定義吸收。
  2. In this paper, the author discusses the orthogonal transformation, pointing out that there is difference in essence between the two condition of equivalence

    摘要對歐氏空間正交變換作了討論，指明了兩個等價條件的不同之處。
  3. There are four kinds of important mathematics ideologies in advanced algebras, namely analogoue ideology, equivalence and classification ideology, transformation ideology, isomorphism ideology

    摘要高等代數中蘊含的主要數學思想有類比思想、等價分類思想、化歸轉化思想、同構思想。
  4. Beginning with the equivalence principal, two types of near - field to far - field ( nfff ) transformation s are discussed systematically, i. e. frequency - domain nfff ( fd - nfff ) and time - domain nfff ( td - nfff ). in td - nfff transformation, the concurrent - processing approach is used, where the contributions to far - field from the tangential electric current and magnetic current on the equivalence surface are calculated " on - the - fly " in step with the fdtd simulation. as a result, it is not necessary to store the tangential current components for every equivalence surface at every time step, and therefore reduce considerably computer storage required for the td - nfff transformation

    在理論部分，本文從電磁場的等效原理出發，系統、詳盡地論述了頻域和時域近遠場變換的基本思想，在時域近遠場變換中採用實時的變換方法，即每進行一個時間步的迭代，就計算一次等效面上該時間步的切向電流和切向磁流對遠場各方向的貢獻，這樣就使時域近遠場變換不需要儲存等效面上每一個時間步的切向電流和切向磁流，大大減小由於近遠場變換而增加的計算機內存需要量。
  5. This article proves that primary transformation of line in a matrix is used to judge the dependence and equivalence of vector set as well as the linear representation of vector and to evaluate the radix and dimension of sum and intersection of vector space

    給出了利用矩陣的初等行變換，判斷向量組的相關性，向量組的等價及求向量子空間的和與交的基和維數的方法。
  6. Secondly, we give a monotonic transformation for the converted single programming problem and prove the equivalence between the converted monotone programming problem and the programming problem with single constraint

    再將轉化后的只有一個約束的規劃問題轉化為一個單調規劃問題，並證明了其等價性。
