While there has no control, the behavior of the system is discussed in Chapter 3. No defines in the point (0,0) of the system brings much difficulties in the research on the kinetic nature near (0, 0). By applying the series theories and methods in the literature on the singular point of nonlinear equations, we solve this problem satisfactorily and give the all possibility of the orbits of the system converging (0,0) as t→+∞ in the First Quadrant.

This paper gives a mathematical definition to that two open planar curves have the same shape based on curvature representation, therefore, a new kind of shape distance is proposed. It is concluded that the problem of computing the shape distance between two open planar curves can be changed to the problem of a functional extremum, and the differential equation is given, which can be used to figure out the shape distance.
