本文指出，Schwinger最近提出的一个建议使人们能够构造一个守恒到忽略中等强k介子相互作用的轴矢量电流。Schwinger还提出，存在一个同位素标量粒子，sigma，它是洛伦兹空间中的标量，不会被看到。粒子的存在使我们能够从与的交叉项中构造一个轴矢量玻色子电流，从而构造一个守恒的轴矢量电流。(交流)
It is pointed out that a recent suggestion of Schwinger enables one to construct an axial vector current that is conserved to the extent that one neglects the medium strong K-meson interactions. Schwinger also suggests that an isotopic scalar particle, sigma , exists which is a scalar in Lorentz space and will not be seen. The existence of the sigma particle enables one to construct an axial vector boson current from cross-terms wth the sigma and so to construct an axial vector current that is conserved. (A.C.)
