The Research on the Generalized Elliptic Curve with Three Foci

This paper gives a new concept of the generalized ellipse with three foci,shows the ploting method and the mathematical models of the ellipse,builds up the mathematical model of the distance from the gravity center M of the ellipse to the moving point P on the curve of the ellipse,presents the transfer characteristics of the ellipse to force and velocity and its applications in the industry.
