In the paper,the generation of striped trajectories in phase space by noise-injection is considered. With suitable amplitudes of noise,the steady-state system orbits appear in rectangular striped shape.The relationship between the shape(including the range and the number of stripes)and some parameters is discussed.The result shows that noise can also generate the striped shape effectively and simply,which is similar to the newly-discovered striped patte generated by controlled Rossler systems.
