The propagation properties of (1+1) D Gaussian double light beams in strongly nonlocal nonlinear media with low losses are studied. By simplifying the nonlocal nonlinear Schrdinger equation which the light propagation in strongly nonlocal nonlinear media with low losses obeys, the propagation model of (1+1) D Gaussian double light beams in the media is obtained. With analysis method, the evolution laws of double light beams propagation are studied, the quasi double solitons solution is obtained. Further studies point out that the trajectories of the two light beams centers in propagation are Airy functions; the two light beams will collide and separate; with the increase of propagation distance, the maximal distance between the two light beams centers will become larger. When the losses increase, the collision spatial period will become smaller, and the maximal distance between the two light beams centers will become larger.
