序列空间

Salience measures reflected in segmentation together with focus shift rules provide cues for attention to visit objects in turn. Object-based saccade sequence in this way is closer to human perception than space-based one.

注意机制按照知觉分割中提供的显著性尺度和焦点转移原则依次检测各目标，形成的基于目标的扫视序列比基于空间区域的扫视序列更符合人的感知。

Comparison of SRY/Sry primary structure of human and bovine, the HMG-box was the singular conserved part, but they were similar in the three-dimensional structure.

比较牛和人SRY蛋白结构，仅在保守区HMG-box处有较高的相似性，但是空间构象却比较相似，都是通过结合DNA螺旋小沟来识别7个碱基的核心靶序列，作用方式也很相似，说明虽然SRY/Sry蛋白在物种间序列差异较大，但蛋白的结构和作用方式却是很保守的。8。

On the basis of state space model of system dynamics, the decomposition of periodic term and trend term in the time series of both power demand and Gross Domestic Product are carried out respectively, and it is discovered that there is a strong correlativity between the periodic term...

文章基于系统动力学的状态空间模型对电力需求与国内生产总值(GrossDomesticProduct，GDP)增长率时间序列分别进行周期项与趋势项的分解，发现电力需求与GDP分解的周期项之间存在很强的相关关系；基于此关系及电力需求增长率序列数据自身的变化规律，采用计量经济模型预测了2004~2008年我国电力需求增长率，以期为当前的电力规划工作提供参考数据。

Based on the chaotic characteristic of time series of power loads and combining the phase space reconstruction theory of chaotic time series and regression theory of supporting vector machines, a short-term load forecasting model based on chaotic characteristic of loads and least squares SVM is built.

以负荷时间序列的混沌特性为基础，结合混沌时间序列的相空间重构理论和支持向量机的回归理论建立了一种基于负荷混沌特性和最小二乘支持向量机的短期负荷预测模型。

We introduce the phasespace reconstruction theory of the chaotic time series and give a method of calculating its Lyapunov spectrum with neural network. This method needs less data and has high precise results.

对于混沌系统单变量时间序列，介绍了相空间重构方法，提出了用人工神经网络计算混沌时间序列Lyapunov指数谱的方法，这种方法就有较高的计算精度，需要的数据点较少，因而具有较强的实用性。

Secondly, according to the theory of retrieving model using time series and the self-memorization principle, the grey self-memory model based on grey system theory and phase space self-memory model established using chaotic theory are put forward, and the two kinds of models are applied to the analogy and forecasting of hydrologic time series, and the application field of the self-memory model is further expanded from extent and profundity.

更进一步，根据时间序列反演建模基本理论和系统自记忆性基本原理，提出了基于灰色系统理论的灰色自记忆预报模型和基于混沌理论的相空间自记忆预报模型，并应用于水文时间序列的模拟与预测，从广度和深度上更加拓广了自记忆模型的应用范围。

At the same time, to reserve the correlation between short snippets, the adjoined sequences between them are considered, instead of breaking these longer sequences simply. This method can reduce the requirement of time and space, and reserve the global information.

为了保留短片断之间的相关性，并不是简单地分割这些长序列，而是同时考虑了短片断之间分界点两侧的序列，这样既可以降低算法对空间和时间的需求，又尽可能地保留了全局信息。

We chose three amino acid sequences from PDB based on SCOP,which all belonged to and had similar fractal dimensions.From the point of view of multifractal,the complexity of the distance of protein and the polar and volume of amino acid sequences are compared.

按照SCOP分类法，从PDB中选取三条同属于类的分维相近的蛋白质序列，利用多重分形分别对蛋白质空间距离以及序列中氨基酸的极性、体积的复杂性进行比较。

When one basin changed from rifting basin to foreland basin, it presents different stages of basin evolvement in time series, and presents different basin types in special series.

从裂陷盆地向前陆盆地的转化过程中，在时间序列上表现为盆地演化阶段的不同，在空间序列上表现为盆地类型的不同。

A space series substituting time series method was adapted and Levins niche breadth index and the Pianka Niche overlap index was applied to calculate the resumption of different age and population niche and niche overlap in spring-autumn grassland enclosed for different years at Zhaosu horse ranch.

采用空间序列代替时间序列的方法，运用Levins生态位宽度指数和Pianka生态位重叠指数，对不同围封恢复年限种群生态位及生态位重叠计算分析。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
