It is clear that the maximum principal component is mainly made up of the supply frequency component. The subspace II is spanned by the other eigenvectors related to the rest components.

子空间I由信号中的最大主分量和噪声所对应的特征向量张成，子空间II由其他分量的特征向量张成。

Throughcalculation, we find that there are remarkable differences between coding and non-coding sequences, and vector from random sequences is closely related to that fromthe coding sequences.

通过计算，我们发现，编码区和非编码区所对应的4维向量有很大不同，并且随机序列与编码区对应的向量较为接近。

基于支持向量回归理论和小波支持向量核函数，提出了一种新的SAR滤波方法。

In this paper as an example of a typical large-span dome roof, the direct superposition method of Ritz vector s are used in the solution of the eigenvalue problem and the cal.

本文以典型的大跨圆拱屋盖为例，将里兹向量直接叠加法应用于屋盖系统特征值问题计算和风致响应分析，其特点是在误差逼近的基础上自动生成一组正交的里兹向量并用于缩减系统自由度数。

It used the inner product and discriminant rule to concentrate the row vectors of boolean matrix step by step, so the frequent item sets of transaction databases can be inducted quickly and intuitively.

即通过向量的内积运算和判别准则逐步浓缩布尔矩阵的行向量，从而快速、直观地归纳出事务数据库的频繁项集。

However,the performance of SVM with Gauss kernel is influenced greatly by the penalty parameter C and the scale parameter σ.

支持向量机的识别性能对参数的选取是敏感的，惩罚因子C和核函数参数σ对支持向量机性能会产生重要的影响。

A sidelight here is that if you look at the mathematical representations of a PM signal versus an FM signal, the difference is that the modulation component in a PM signal is the mathematical derivative of the modulating signal in the FM signal.

如果你看调相PM信号和调频FM信号的数字表达式的对比，它们的不同点是调相PM信号调制向量是调频FM信号调制向量的数学派生。

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。
