  1. The physical origin of the gauge transformation is a mystery.

    這個規范變換的物理起因還是個謎。
  2. We examin e the generation of bell state in bose - einstein condensates of two interacting species trapped in a double - well configuration analytically and the density of probability for finding the entangled bell state is given. we find that the oscillation amplitude of the probability of density for finding the entangled bell state becomes greater as the ratio of the interspecies interaction strength and the tunneling rate increases, moreover the self - interaction strength of the component a ( b ) has no effect on it. also we use the time - dependent su ( 2 ) gauge transformation to diagonalize the hamilton operator, obtain the berry phase and analytically the time - evolution operator

    此外我們還研究了在雙阱玻色-愛因斯坦凝聚中糾纏態的演化，研究發現隨著組分間相互作用和隨穿率的比值的增加系統演化到bell態的概率變大，而且組分自身內在的相互作用對形成bell態的幾率沒有影響；並且用含時su （ 2 ）規范變換對角化哈密頓量得到了系統的berry位相和時間演化算符，並研究了量子隨穿過程。
  3. 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。

  5. We found the generators g of an local elliptic su ( ri ) g ( su ( n ) ), which transform covariantly by the global gauge transformation of an - by acting on hn we establish the isomorphism of an and ?,

    此外，我們還發現了局部橢圓su （ n ）代數g的生成元g ，它是按a _ n的整體規范變換進行協變變換的。作用在h _ n上，我們建立了a _ n和g之間的同構關系。

  7. Using lewis - riesenfeld theory, we obtain exact solutions of the time - dependent system, then we recover both n - pulse method based on time - evolution operator of the system and stirap method in terms of instantaneous eigenstates with the help of time - dependent gauge transformation

    利用含時規范變換理論得到系統的精確解，我們用時間演化算符同時得到文獻中分別採用-位相法和stirap （受激拉曼散射）方法得到的結果，因而更具有普遍性。
  8. According to the dirac constrain theory and the extended condition, we deduce the gauge generators, show the brst transformation of ( 1 + 1 ) dimension o ( 3 ) non - linear model under the new general condition. we first gain the new general commutation relations of ghost field, deduce the brst charge from gauge generator, complete the general brst quantization of the model, get green function, connecting green function and generating functional, gain three kinds of ward identities. at last, we complete the brst quantization of o ( 3 ) non - linear model with topological term in ( 1 + 1 ) dimensions space - time
