field redefinition meaning in English

字段重新定义

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
然后利用seiberg - witten映射，我们研究了不同空间的规范对称性的等价问题，并对非对易空间的电磁场进行了微扰分析，最后我们对seiberg - witten映射的松动进行了讨论，研究发现这些松动中的一部分可以由规范变换吸收因而是可以忽略的，由于物质场的存在，另外一部分很难用规范变换和场的重定义吸收。
