文摘The generalized Lagrangians of matter field and gravitational fields are specified and their invariances under (ε^(mn), ξ~μ) transformations in the space-time with torsion are studied. The possible forms of coupling between gravitational fields and matter field as well as the possible types of gravitational Lagrangian are derived. Some physical quantities are introduced and several interesting conclusions are discussed.
