| Abstract: | The two-dimensional string gravity model with curvature and torsion is studied in this paper. In the stationary case, it is proved that equations of the motion and extremal curves are integrable. It is found that the velocity of a massive point-like particle can be expressed by the first integrals of these equations. Moreover, the numerical solutions of the field equation are inverstigated, and the influence of string coupling on the motion velocity of the particle is also analyzed. |
