摘　　要：流代数的基本概念是各种“流”算子的矩阵元在物理实验中是可以测量的 .物理流在互相交换下有与场论的一个简单类型的矢量流相同的代数性质 .The essential idea of current algebra is that matrix elements of various “current” operators are measurable in physical experiments.The physical currents have the same algebraic properties under commutation as the vector currents of a simple class of field theories.By applying current algebra sum rules and introducing infinite momentum,problems of the free-quark field theory can be solved.

关 键 词：流代数 自由夸克场论 无限大动量 矩阵元 物理流 矢量流 求和规则
