It This paper uses the equivalence relation between the three-dimensional intends homogeneous vector field and three-dimensional homogeneous vector field, while drawing on the alignment vector field research methods, some of the conclusions of the homogeneous vector field successfully extended to the intended Qitimes a vector field. In this paper, three-dimensional space of the system has been to transform transformed into spherical and conical, projected onto the plane up to investigate the geometric properties, and finally return to the three-dimensional space to derive the geometric properties of the original equation by the same cone. In this way we get the nature of such a model in space plays an important role and significance of similar biological model. |
