摘要

Using RXTE observations, we investigate the evolution of inner disk radius (R_(in)) of Cir X-1 during two cycles and find obvious orbital modulation. We argue that the modulation is attributed to its high orbital eccentricity. The disk luminosity is inversely with the inner disk temperature (kT_(in)), which is ascribed to the slow increase of kT_(in) and, however, the rapid decrease of R_(in) during the passage for the neutron star to depart from the companion star.
