The AR spectrum is not restricted by length of data, and AR spectrum parameters are sensitive for law of condition change. Autoregressive transformation is made to vibration signals, and then AR spectrum coefficients are got which can be utilized as feature vectors. Fault diagnosis method for centrifugal pump Based on AR and 2D-HMM is produced in this paper. The topology of this model and its parameters were introduced too.

The interval estimation information given by estimators is classfied. The bargaining interval and bargaining value is also determined for each class information. Then, the information of the bargaining interval and bargaining value is integrated by utilizing the induced ordered weighted averaging operator. The problem to choice the weighted vector of the IOWA operator is also discussed.

在加权近似空间中提出了关系矩阵和布尔列向量加权α下乘法和加权α上乘法的概念。

Firstly, the decision matrix is transformed into an objective matrix, and then the weight of every objective is determined by means of entropy coefficient method. By Integration of experts' knowledge, the acceptable lower bound of degree of satisfaction and acceptable upper one of degree of dissatisfaction of every objective are decided. At last, by using the weight vector and the acceptable lower boun...

首先将决策矩阵转化为目标矩阵，然后利用熵权系数法计算各个目标的权重，综合专家的意见得到对于每个目标可以接受的满意度的下界和不满意度的上界，最后利用得到的权重向量以及得到的满意度的下界和不满意度的上界计算各方案的vague估计值，将得到的vague估计值按照评分函数进行排序，得到方案的排序结果。

In general,the convergent sequence and bounded set are concepts only in topological spaces.

收敛序列和有界集一般是拓扑空间中的概念，文章首先引入序列收敛C和L-空间(给出某种序列收敛关系的向量空间)，然后在其中定义有界集。

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.
