摘　　要：混沌电路的设计是混沌通信和混沌加密等应用的先决条件,因此混沌电路的理论研究和设计具有十分重要的意义.本文对作者以前提出的二维混沌电路的方法进行推广,论述如何在三维空间中构造混沌吸引子,从而产生混沌信号.该方法的最大优点是:采用模块化设计思路,混沌吸引子的形状可以根据实际需要来设计,易于电路和集成电路实现.Designing chaotic circuits is prerequisite to chaotic communications, chaotic encryption etc. Therefore the fundamental research on it is extremely significant. This paper generalizes the method of designing 2D chaotic circuit proposed by the authors before. By this new method, it becomes simple and flexible to design chaotic dynamic systems in the 3D state space. The remarkable advantage of this design method is that one can choose complexity of the chaotic attractor as needed by combining the three kinds of modules, and the chaotic attractor can be easily implemented with a circuit or an integrated circuit.
