In the end of this chapter,weprove a local nilpotency property of operators on modules(Theorem 2.3.3)whichis one of the main theorems of this work.

In the second chapter, the basis concepts of interval-valued fuzzy sets are given, and a new definition of interval-valued implication operator and triangle norm is proposed, then some properties are proved.

By means of estimates for three-dimensional discrete derivative Green's function , the theory of the interpolation operator of projection type and the technique of cancellation of elements, for several usual elements in the three-dimensional setting, including rectangular parallelepiped elements, tetrahedr.

借助三维离散导数Green函数的估计，投影型插值算子理论和单元合并技术，本文详细讨论了几种常用三维单元(包括长方体元，四面体元和三棱柱元)的有限元解梯度的最大模超逼近，均获得了高精度的超逼近结果。

Petre Hajek have proposedBL algebra based on the three continues triangle norms and construct Basic Logicsystems correspondingly.

A sensor with balanced detection is introduced to the BB84 protocol and the theoretical model of the QBER is established with POVM (Positive Operator Valued Measurement).

论文将双平衡探测结构引入BB84模型中，利用半正定算子值测量建立了接收端在偏振模影响下的误码率模型。

The quantum quadratic residue codes are also extended in a nice way, most of which allow, the projective unimodular group, to act.

构造出量子二次剩余码的扩展码，与经典情形类似，对几乎所有的，量子二次剩余码的扩展码都以射影幺模群为自同构子群。

The method takes and combines the advant- ages of both the subspace iteration method and Ritz vecter method.

0引言 目前求大型结构部分模态参数已有许多成熟的方法，如R八z向量法川子空问迭代法，1和Lonozo。

Mould industry is a most important industry of in the world, development of it already the life with people , the rapid and intense relevance working and studying, especially plastic mould, design that originally time though be a comparatively simple eye shadow box cover mould, but small but complete, its design process has included the plastic model designing a lot of fundamental process flow , has selected and used the XS-ZY-125 type injection machine such as the injection machine choice.

模具工业作为世界上最重要的一个工业，它的发展已经与人们的生活，工作和学习紧密相关，特别是塑料模具，本次设计虽然是一个比较简单的眼影盒盖子的模具，但是麻雀虽小，五脏俱全，它的设计过程包括了塑料模设计许多基本的工艺流程，像注塑机的选择，选用了XS-ZY-125型注塑机。

The left singular vector of the projection has been tracked by the projection approximation subspace tracking algorithm. Then the modal parameters are obtained by least square method. At last an experiment is made using a cantilever beam to prove the efficiency and stability of the method by changing the frequency band of the exciting signal.

通过子空间跟踪算法，不断跟踪计算投影的左奇异值向量，再利用最小二乘法求出系统的模态参数，最后用悬臂梁作为实验模型，通过不断改变系统激励的频带范围，验证方法的有效性及稳定性。

Firstly,surd or sonant judgment with each voice frame is done,then the multi-scale wavelet analysis is done only on the sonant frames to get pitches.In order to get accurate pitches,the intervals of local modulus maxima of dyadic wavelet coefficients are corrected according to amplitude information and appearance probability information.

针对这一问题，提出一种基于小波变换的基音周期提取改进算法，将TEO算子与二进小波变换结合起来，首先进行清浊判定，然后只对浊音帧采取多尺度小波分析提取周期，提出用幅度信息和出现概率信息校正二进小波模极大值间距，从而得到准确的周期。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
