By this approach, the structural features and statistical features of characters are firstly extracted, then they are normalized to the input vector of neural network, and RBF neural network is used for recognition.

该方法首先提取字符的结构特征和统计特征，以它们作为神经网络的输入向量，然后用RBF神经网络进行识别。

A fault diagnosis based on wavelet and PNN was introduced, which firstly uses Mexican Hat wavelet to transform diagnosis signal and extract energy normalized vector, then uses PNN to output fault as a classifier.

针对煤矿主通风机故障与征兆对应关系复杂的特点，以及利用传统BP网络进行故障诊断存在训练速度慢、易陷入局部极小的缺点，提出基于小波和概率神经网络的故障诊断方法：先利用时频两域有紧支撑能力的MexicanHat小波变换故障信号并提取能量归一化故障特征向量；然后将概率神经网络作为诊断决策分类器，输出故障模式。

This mechanism overcomes the disadvantages of the implement mechanism of RBAC which have already been presented,and it has both the advantage of the small number of lock vector updating and the advantage of low possibility of overflow.

它不仅能很好地克服已有RBAC实现机制存在的缺点，还兼备了对锁向量修改次数少和发生溢出可能性小的优点。

In this paper, to establish a vector error correction model, based on the use of impulse response function and forecast variance decomposition to describe China's agricultural infrastructure development and rural economic growth dynamic relevance.

本文以建立向量误差修正模型为基础，使用脉冲响应函数和预测方差分解来描述中国农业基础设施发展与农村经济增长之间的动态相关性。

According to this method, intrusion detection is regarded as one-class classification problem.

该方法将入侵检测看作是一种单值分类问题，建立正常行为的支持向量描述模型，通过该模型可以检测各种已知和未知的攻击行为。

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。
