提出了一个新的具有两个大的正李雅普诺夫指数的超混沌系统，并进行了物理实现。谱分析表明，该系统在超混沌模式下具有极宽的高幅值频带，验证了其不寻常的随机性质，并表明其在保密通信等相关工程应用中的巨大潜力。
A new hyperchaotic system which has two large positive Lyapunov exponents is presented and physically implemented. Spectral analysis shows that the system in the hyperchaotic mode has an extremely broad frequency bandwidth of high magnitudes, verifying its unusual random nature and indicating its great potential for some relevant engineering applications such as secure communications.
