66529 To 0.90675. The none-scale range and the range of the variation were very large.

重性状的信息维数都集中在0.66529~0.90675，而且无标度区较大，测度范围广。

In this paper,an exponential relation between the reciprocal of fractal dimension of urban boundaries and compactness ratio or circularity ratio i...

边界维数与紧凑度的数理关系反映城市地理系统宏观规律与微观结构的内在联系，这类关系正是地理空间复杂性关注的问题之一。

In order to diminish the effect of reconstructed parameters to prediction of chaotic system, a combined model for

为了减小混沌系统的重构参数对预测结果的影响，提出了基于多嵌入维数的风力发电功率组合预测模型。

In this method, the parameters to be estimated are divided into two sections, the number of equation dimension is reduced by half, so the solution of equation is simplified, and the working efficiency is greatly raised.

在这种解算方法中，由于将待估参数分成了两部分，使原本庞大的高维方程组的解算得以简化，把待求参数的维数减半，大大提高了工作效率。

Support vector machine procedures can be carried out the classification and regression, the effect better than the neural network, there is no dimension disaster problem, it is more good modeling method.

详细说明：支持向量机的程序，可以进行分类和回归，效果比神经网络好，没有维数灾难的问题，是比较好的建模方法。

And for multi-dimension the conditions of the problems with sufficiently regular and star-shaped domain are also given, which have no solutions in Sobolev space.

给出了在空间维数为一时所论问题有无界解的条件，以及在高维空间时，区域充分规则和星形情形下，所论边值问题在Sobolev空间无解的条件。

The more regular is surface topography of fracture 2, 5, 6, the smaller is fractal dimension.

断口2、断口5和断口6外观形貌较规则，分形维数较小。

We proposed to use wavelets and a regularization method to solve the small sample problem.

我们提出了基于小波分析的解决"维数灾难"的正则化方法。

Renormalization group method which calculates fractal dimension theoretically is the most useful tool when we study critical phenomena of phase transition.

重整化群方法是研究相变的临界现象最有力的工具，它是一种由理论求得分形维数的方法。

In this paper, we study the phase diagram of the deformed t-J model in one dimension in the regime where deformation parameter and J/t are both positively small but comparable to each other by using the bosonization field theory and renormalization group technique.

我们利用重整化群方程对相应的相互作用项的标度维数进行了分析并以此来判断相应的电荷与自旋元激发是否存在能隙。同时我们用准经典势的方法讨论了各种序参量在基态能量中的竞争情况。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
