Firstly,the wavelet-based contourlet coding using an SPIHT-like algorithm is utilized on the plain image,and as a result,the compressed datum stream could be achieved which is then mapped to a 3D bit matrix. Afterward,a chaotic sequence is generated by Lorenz chaotic map,and it is preprocessed to a bit sequence which is used to permute and substitute the elements of the 3D bit matrix achieved above. In the end,the processed 3D matrix is mapped back to datum stream,and the encrypted compressed image could be achieved if decoding and inverse transform are performed on the datum stream.

首先采用基于小波的Contourlet变换的类等级树集合分割编码算法对明文图像进行压缩，得到压缩数据流，然后将压缩数据流映射为一个三维位矩阵；利用Lorenz混沌映射产生混沌序列，并对其进行预处理得到比特值序列，根据比特值序列对上述三维位矩阵进行置乱和替代操作；将置乱和替代后的位矩阵重新映射为数据流，并对其进行解码和反变换操作，得到加密后的压缩图像。

Since that time, much effort has gone into showing that Lorenz's basic ideas about these equations were correct.

从那时起，大量的努力投入到证明 Lorenz 关于这些方程的基本思想是正确的。

RESULTS: Compared with control group, SDNN, SDANN, TP, VLF and scattergram length in organic heart disease group were significantlylow. Results of Lorenz plot showed that most of controls were comet shape (82.22%) as well as organic heart disease patients were complex shape (42.22%), triangularshape (35.56%) and torpedo shape (8.89%). L correlated well with SDNN, SDANN, TP and VLF. Scattergram dispersion correlated well with rMSSD, PNN50 and HF.

结果：与对照组比较，器质性心脏病组的SDNN、SDANN、TP、VLF及Lorenz散点图长度均显著下降，对照组散点图82.22%为彗星状，器质性心脏病组复杂形、扇状及鱼雷状分别占42.22%、35.56%及8.89%； L与SDNN、SDANN、TP、VLF呈显著的正相关，散点图离散度与rMSSD、PNN50、HF呈显著的正相关。

Lorenz Helbling is a Switzer, who opened ShanghART Gallery, which is known in Shanghai in the reign of Chinese modern art.

Lorenz Helbling，一个瑞士人，在上海开设的香格纳画廊成为了中国当代艺术领域中一个不能被遗忘的名字。

However, few reports discuss the smooth Lorenz-like system with multi-wing attractors,and the attractors with both hyperchaotic dynamics and multi-wing topological structure are seldom reported. Based on the existing smooth hyperchaotic system,the common characteristics of these systems are analyzed.

构造超混沌系统在目前并非难事，在Chua系统基础上构造具有多涡卷拓扑结构的吸引子也有很多系统方法，但较少有文献讨论基于Lorenz系统族的拥有多翼结构吸引子的光滑混沌系统，而同时具备超混沌特性和多翼拓扑结构吸引子的光滑混沌系统则更少报道。
