Introducing the Korteweg-de Vries equation with a damping term and anexternal force, the behaviors of solitons under the Gaussian white noise is studied.In the non-damping case, a height and a width of the soliton are proportionalto t - "" and t "' respectively, for large t. The asymptotic form of the multi-solitonis also discussed. In the damping case, it is found that a width of the soliton ismuch narrow while a height is much small as compared with the non-dampingcase. A new idea for the analysis of inhomogeneous soliton equation is suggested.
