ward identity meaning in Chinese
沃德恒等式
Examples
- 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
最后依据dirac约束规范理论和推广的条件，导出了规范生成元，推导出了1 + 1维o ( 3 )非线性模型的新的一般条件下的brst变换，给出了其brst变换与dirac规范变换的等价性，首次得到了鬼场的一般对易关系，且其一般参数为零时就回到通常的鬼场的对易关系，第一次由规范生成元导出了brst荷，进而完成了此模型的一般的brst量子化，并在此基础上进一步导出了此系统的green函数、连通green函数生成泛函和正规顶角生成泛函，获得了三种不同的ward恒等式。 - Thereafter , we summarize the intrinsic properties of brst transformation , the canonical ward identities of phase space and the gauge generators , further sum up the first - class & the second - class constrains ( in hamiltonian system ) and the relations between the first constraints and gauge transformation generators
进而综述了brst变换的内秉性、相空间变换的正则ward恒等式和规范生成元，综合地讨论了约束hamilton系统中第一类约束和第二类约束以及第一类约束与规范变换生成元的关系。
