• This thesis begins to analyze these questions , and the analysis is made up of five parts . they are as follows : chapter 1 : we expatiate on the meaning and the measurement of ' industrial isomorphism " , and give demonstrative analysis on the evolvement trend of it in our country
  本文就是针对这一系列问题展开分析的，其过程可以分为五个部分：第一章首先阐述了产业同构的涵义及其测度方法，并对我国的产业同构程度演化趋势进行了实证分析。
• Subsequently we make use of the isomorphism property between the behavior of petri nets with exponentially distributed transition rates and markov process to acquire markov chain , and compute the subsystem ' s mean time to delay and transfer probability of subsequencial state , which present the theoretical evidence for intrusion detection system ' s design
  随后利用随机petrinet和连续时间的马尔可夫链同构的性质，应用所获得的同构马尔可夫链对求得稳定状态概率的子系统的平均延时时间和后继状态转移概率进行了详细的计算，从而为入侵检测系统的设计提供理论根据。
• We can give different structures on a tensor product h q to make it a bialgebra or hopf algebra . in [ 1 ] radford constructed a hopf algebra a x h with the smash algebra structure and the smash coproduct coalgebra structure , and pointed out that if a bialgebra b has a hopf subalgebra h and a projection ! : b - - > h , then there must be a subalgebra a of b such that b @ a x h is a bialgebra isomorphism
  在张量积hq上可以给出不同的构造，使它成为双代数或hopf代数， radford在文献[ 1 ]中构造了以smash积为代数结构，余smash积为余代数结构的hopf代数a h ，并指出若b是双代数， h是b的子hopf代数，且存在投射： b h (即是双代数同态，且| _ h = id _ h ) ，则一定存在b的子代数a ，使ba h是双代数同构。
• In the second part , a class of left - continuous isomorphic to r0 t - norm are given . the concept of isomorphism among implication operators is introduced and it is proved that two implication operators are isomorphic if and only if the two t - norms residuated to them respectively are isomorphic . moreover , modifications of classes of a - tautologies under isomorphisms are investigated
  紧接着，引入了蕴涵算子同构的概念，并对伴随情况下t -模同构与蕴涵算子同构之间的关系进行了讨论，初步研究了同构的蕴涵算子对-重言式类的影响，得到了关于系统的广义重言式分类定理。
• And by far , most theories of wavelet analysis are established in , but this method is rare to be known and exists defects in the reproducing kernel space with good properties . then in the reproducing kernel space , isometric isomorphism of relation is founded between and by differential operator . and starting from the haar basis , multi - resolution analysis inis gived by folding method ; then multi - resolution analysis and orthonormal wavelet in are obtained through integral transform from to . then the reproducing kernel space can be expressed by wavelet spaces
  于是，在再生核空间中，利用积分算子建立了空间与hilbert空间的等距同构关系；并且从haar小波出发，由折叠法实现的空间中多尺度分析通过积分变换得到中多尺度分析和正交小波，使得再生核空间可以由小波空间来刻划；从而对空间中的函数，给出了小波逼近具体表达式和相应的采样公式，形式简单易于数值分析。
• The following algorithms have been proposed and tested in the thesis : 1 frequency selective fading : combine the isomorphism between the input space and the output space and propose a new approach to blind equalization of the channel . compared with conventional methods , the new approach offers lower computational complexity , better performance , and more robust against the over - determination of the system order ; 2 time selective fading : a new approach to the equalization of time selective channel based on the zero - forced equalizer is proposed which is more simple in its structure of algorithm ; 3 time - varying channel : using the instantaneous mean value changes of the output signal to extract the information of channel variations and model it using ar model , kalman filter is then employed to track channel variations , it bears faster ability in tracking the variation of tv channels ; based on the isomorphism between the inputs and the outputs and some of the approaches using in mimo system , a new algorithm of equalization of simo time - varying channel is proposed , which also share the merits of being robust against the over - determination of the system order ; model the time - varying channel using the multi - resolution decomposition wavelets , and then a blind identification method based " on the model is proposed ; at last , a new model for equalization and identification of mimo system is proposed
  主要工作在以下几个方面： 1 、针对频率选择性衰落信道：结合输入输出空间同构关系提出一种新的频率选择性信道均衡方法，与传统方法相比，该方法计算量更小，收敛速度更快，性能更优，且对系统阶次的过确定表现稳健，具有实际均衡应用价值； 2 、针对时间选择性衰落信道：提出一种基于迫零均衡的时间选择性信道均衡方法，算法结构简单； 3 、针对时变色散信道：利用瞬态均值曲线提取信道时变信息，对之ar建模，利用卡尔曼滤波器跟踪时变信道抽头变化，可以快速跟踪信道变化；基于输入输出空间之间的同构关系以及多输入多输出系统的处理方法，提出了新的单输入多输出色散时变信道均衡与识别算法，同样具有对信道阶次过确定保持稳健的优点；结合小波多分辨率分析提出一种基于小波模型的信道盲识别算法；研究时变的多输入多输出系统的盲均衡与盲反卷积问题，给出一种时变系统处理模型。
