COMPOSITE FIELD THEORY AND VECTOR MESON DOMINANCE (VMD), PARTIAL CONSERVATION OF AXIAL VECTOR CURRENT (PCAC), FIELD-CURRENT IDENTITY AND SOME PROBLEMS OF CURRENT ALGEBRA
复合场场论和矢量为主(VMD)、赝矢流近似守恒(PCAC)、场流关系以及流代数的一些问题

We derive the theory of vector meson dominance, partial conservation of axial vector current, field-current identity and the combined algebra of field and current with the application of the composite field theory. It can be shown that an unified theoretical foundation can be given by the composite field theory for these various theories.
