查询词典 characteristic

A sequenced method in consideration of the sample range was proposed to rationally array classifiers of a support vector machine with binary tree architecture. A sample distribution radius and a sample distribution distance were introduced to estimate sample range of all classes in high-dimension characteristic space. The classes with bigger sample range were classified earlier in the higher nodal point of the binary tree architecture, and were given wider classificatory areas in the characteristic space.

考虑到样本的分布情况对分类器推广能力具有较大影响，提出一种次序二叉树支持向量机多类算法，采用样本分布半径和样本分布距离估算各个类别的样本在高维特征空间中的分布情况，把分布半径较大的类别或者分布距离较大的类别较早地分出来，并且在特征空间中给其划分较大的分类区域。

In the fourth chapter, firstly it introduces the Boolean functions algebraic expressions of the 2-value clock-controlled stop-and-go generator and Gunther generator. It reveals the balanced property of the two kinds of Boolean functions, and studies the Walsh cycle spectrum and the autocorrelation function. It also obtains the coincidence rate of their output sequences with affine sum of some bits of input sequences, and analyzes their ability of resisting the best affine approximation cryptanalysis and differential cryptanalysis. Secondly, we properly present a new definition of the Best Affine Approximation, namely BAA on the Boolean vector functions, followed by the spectral characteristic of such defined BAA attacks through using the decomposition formula of the union distribution for random variables. A lower bound of such BAA attacks is proposed. Finally, we also study the spectral characteristic of the second kind of nonlinearity of Boolean vector functions, followed by a higher bound of such nonlinearity. Furthermore, the limited relationship between the second kind of nonlinearity of Boolean vector functions and the linear structure of the linear combination of every component is analyzed.

The results indicated that the high level density functional theory calculations can be used to predict the 13C chemical shifts of the modified nanotubes. The calculated results also provided the characteristic chemical shifts values of nitrene (superscript -), carbene (superscript -) and 1,2- and 1, 4-fluorinated nanotubes, which would be helpful for experimental spectrogram assignments. Combined with NMR experiments, these predicted characteristic chemical shifts can be further used to monitor the addition mechanism and the extent of surface modifications on nanotubes.

Compared with the corresponding BEAS-2B cells, the shapes of cells and nuclears, the shapes and quantity of cell organs were not significantly changed in the 1st, 2nd, 5th passage BEAS-2BNNK cells. The 10th, 15th passage BEAS-2BNNK cells, which had swelled cell and cell organs and abnormal nuclear and enlarged the nucleoli gradually and increased the quantity of the cell organs and activated their function, showed the characteristic of transformation cells. The 20th, 25th passage BEAS- 2BNNKcells, which had obvious aberration of the cell and nucleoli and had cataclasm of nucleoli and decreased cell organs, showed the characteristic of tumor cells.

It's an experimental creation period from "Boatman's Elegy" to "Sirius" during which the performance of poetry's perception and the knowing are not mature/Under the influence of the west modernism art, his poetry has been experienced from the new moon romantic to the modernism. It's his mature period from "Lotus's Association" to"Separates the Water Goddess of Mercy". During this time his poetry's intellectuality and sensibility tends to be mature. Through the reconsidering of the westernization, the poet starts to inaugurate a new sky, and the poetry displays a bright neoclassic principle characteristic, then penetrates into the traditional nationality culture;and the "Bestows on from Cercis chinensis" is the deepened time until now which the poet displays for all kinds of practical styles, which includes multiplex characteristic.In his poetry, the intellectuality blends with sensibility, the sensation combined with logos.

从《舟子的悲歌》到《天狼星》是诗人创作的实验期，这一时期诗歌的感性和知性的表现还不成熟，其间由于受西方现代主义艺术的影响，其诗歌经历了从新月浪漫派到现代主义的变化；从《莲的联想》到《隔水观音》是诗人创作的成熟期，这一时期诗歌的感性和知性表现趋于成熟，诗人通过对西化的反思开始"浪子回头"，诗歌表现出鲜明的新古典主义特征，进而深入到民族传统文化之中；而自《紫荆赋》至今是诗人创作的深化期，表现为兼容并蓄的写实风格，并具有多元取向的特征。
