| 摘 要： | We study the propagation of (1+1)-dimensional spatial soliton in a
nonlocal Kerr-type medium with weak nonlocality. First, we show that
an equation for describing the soliton propagation in weak
nonlocality is a nonlinear Schr?dinger equation with
perturbation terms. Then, an approximate analytical solution of the
equation is found by the perturbation method. We also find some
interesting properties of the intensity profiles of the soliton.
