At first, we transfer the integro-differential equation to a first order system. Then, by the phase plane analysis, we obtain the behavior and classification of solutions. Finally, we can draw the corresponding curves of the solutions and we give the code of graphics by Mathematica for your reference.穩定旋轉螺旋波曲率流曲率相平面steadily rotating spiral wavecurvature flowcurvaturephase plane
