摘　　要：考虑器件实现方面的简单性，提出一种新的混沌方程模型，并通过单向耦合法构成超混沌网络。通过微机模拟表明网络具有丰富的混沌、超混沌现象。进而在单向耦合法基础上，提出参数耦合法，利用此方法，构造成的二维混沌网络具有超混沌动力学特性。网络具有高效、灵活、易于器件实现的特点。这种新的混沌方程及超混沌网络模型可望在提高激光器的输出功率。This paper introduces a new chaotic equation in consideration of device simplicity.And its lattice is built by one way coupled map lattice.Computer simulation shows that the lattice exhibits abundant chaotic and hyperchaotic phenomena.Further,on the basis of this one way coupled map lattice,a parameter coupled map lattice is proposed with which a two-dimensional lattice can be formed and hyperchaos is produced.The lattice is characterized by high efficiency,flexibility and device simplicity.The mew chaotic equation and its lattice are expected to be widely used in the fields of improvement of laser output and covert communications,etc.
