Abstract

This paper is an improved version of the thesis �?�5�??.The ECT Spin-Gravitational Field theory is the promotion of the general relativity (Einstein gravitational field theory) in curved spacetime with torsion,it eliminates the contradiction between the Einstein gravitational field theory and the Dirac electron field theory.The simplified form of the ECT spin- gravity theory has a limit of Einstein gravitational field theory,so the ECT spin-gravitational theory should be more correct than the Einstein gravitational field theory. In order to obtaining a clear physical picture and analyzing a specific physical problem, the given Riemann background presentation of the ECT spin-gravitional field has been established through separating the physical effect of spin-gravitional field from the given Riemann background spacetime in this article. In this article,the gauge conditions and simplified form of the ECT spin-gravitational field has been discussed in a given background spacetime.
