Abstract : with adopting of a frame of the principal fibre bundle . the article constructs a unified model of gravity and electromagnetic with torsion both in internal sp ace and in four - demensional space - time . the curvature on the bunde is calcula ted using connection theory in the principle fibre bundle . the action is construc tod with the curvature . the field equations are achieved . finally a discussion is made
文摘:应用纤维丛理论，在内部空间和四维时空引入挠率，建立了引力与电磁场的统一模型.利用纤维丛联络论求出主丛的标曲率，由它构造作用量，求得场方程，最后作一些讨论
