Although the disperse model is beautiful and sententiously, the problem is NP-hard problem, when the number of aminophenol is very huge, the style of the difficulty of settle the problem is exponential, solving the problem is impossible.

离散模型固然很简洁优美，但是蛋白质结构的预测问题是NP-HARD问题，当蛋白质一维氨基酸序列的链长n很大的时候，计算时间随着问题规模的增加呈指数方式增长，求解将变得非常困难。

The storage method utilizes the periodic orbits embedded in chaotic attractors for information storage. The main idea is to map periodic points on the UPO inside the attractors to some specific information alphabet according to some mapping rule, and thus represent an information string as a sequence of periodic points.

这种存储方法利用离散时间混沌系统中的周期态进行信息存储，其核心思想是将吸引子中周期轨道上的周期点按照一定的规则映射为一定的信息符号，进而用混沌系统的一个周期点序列来代表一个信息串或字符串。

Consequently, the vertical TEC around the receiving station was exported. Through this method, the vertical TEC got is an average value of a prick angle around the vertex. With the statistics of dispersion and the high precision data collected in Kunming station, the authors calculated the day by day time sequence value of total electron content in altiplano zone ionosphere. Based on this, they described the characteristics of TEC Sunday-changing in double-hump zone, comparing with CORS of Kunming.

这种方法得到的垂直TEC为天顶周围一锥角内的平均值，通过离散度的统计，并结合昆明站采集得到的高精度数据计算了该地区电离层2007年6~8月的电离层电子浓度总含量的逐日时间序列值，在此基础上对照昆明市连续运行参考站CORS描绘出了对于处在双驼峰区里该地区TEC日变化的特性。

Discrete Ambiguity Function is used to estimate parameters of LFM signal after improving SNR based on recomposing sequences.

摘要提出了一种基于序列重组提升输入信噪比，然后利用离散模糊函数估计LFM信号参数的新方法。

In this paper, a cube is used to denote the data-source of the video, with the interaction of the mouse, a large infinite imagined-plane is daggled to cut the cube in any directions, then it gets a cut-plane; After calculating the discrete points of the plane, the points can then be indexed to get the RGB value of the original points in the video-cube, to show the plane in the form of 2D instead of 3D.

用一个立方体表征视频帧序列数据在空间的存在形式，通过拖曳鼠标的交互作用，拖动一个假想的无限大平面任意切割该立方体，获得一个切面片；进而求解该切面片上的离散整数点，再通过这些点去索引视频立方体中对应点的像素颜色值，把该空间切面片以平面图的形式展示给用户。

The split between the two groups can hardly be papered over.
