摘要：
We discuss Bianchi type-VII0 cosmology with a Dirac field in the Einstein-Cartan (E-C) theory and obtain the equations of the Dirac and gravitational fields in the E-C theory. A Bianchi type-VII0 inflationary solution is found. When it 3/16S(2) - sigma(2) > 0, the Universe may avoid singularity.
