But this is not unique mode, when particularly u t cannot ( ( ) be solved. In the modern theory of circuit and system, we can select three dynamical variables in the nonlinear system to constitute 3-dimension phase space. The mutual nonlinear relation among three dynamical variables can be described by a bounded space curve. This is 3-dimension phase portrait. The nonlinear dynamical systems of regarding N 3 variation may constitute N -dimension Euclidean space. The bounded space curve cannot be represented by concretely ex- plicit parametric form in math. It cannot be solved analytically by human. However, the graphic solution can be plotted by numerical simulation. If the bounded space curve is non-periodic in si- mulation interval, this is orbital chaos of continuous time system. This paper research
