Based on the linear coefficient character of Lorenz attractor and Chen's attractor, we coined a 3dimension nonlinear dynamics, and studied its chaotic characters, including the space trajectory, the largest Lyapunov exponent, the Lyapunov exponent spectra and the Poincare map. All these characters show that the nonlinear dynamics exists chaotic attractor.
