中文摘要：

提出了一种将混沌系统的单螺旋结构转变为双螺旋结构的新方法。通过将典型的三维Genesio-Tesi单螺旋混沌系统和与它关于某点成镜象映射的混沌系统融合，从而构造出一个新的双螺旋混沌系统。对构造的新混沌系统进行计算机仿真和实际电路仿真分析，实验结果显示了该设计方法的正确性。

英文摘要：

A novel method of transforming single-scroll to double-scroll structure of a chaotic system is introduced. This method integrates the typical three-dimensional single-scroll Genesio-Tesi chaotic system with its image-mapping system about a certain point, and consequently reconstructs a new double-scroll chaotic system. Then, it has been simulated by computer and the corresponding circuit implementation of the reconstructed double-scroll chaotic system. The correctness of the method is guaranteed theoretically by computer simulation and circuit implementation.
