The main job and contribution of this paper are as follows:Based on narrowband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, compute the cross-correlation function of FH signals from multichannels, then we get the cross power spectral density matrixCSDM Secondly, select the hops of FH signals from the CSDM via processing and analyzing the CSDM, meanwhile reduce the influence coming from noise, fixed frequency signal and other interferences; Lastly, estimating the DOA of every hop and according to the DOA, we can separate the hops, get the number of FH signals and their parameters. Propose a new method for designing the threshold in FH signal detection. This method makes it easy to get the threshold by theoretic computing and it can extremely reduce the interference of non-FH signals.Based on broadband signal processing, we propose a new method for FH signal blind detection and blind parameter estimation. Firstly, get the DOA of the signals by wideband spatial spectrum estimation; secondly, separate the signals by spatial filtering using wideband beamformer; Lastly, we propose two methods for FH signal blind detection and blind parameter estimation, one is for several constant hop-rate FH signals whose dwell-time are different and another is for a single FH signal whose hop-rate is alterable.By employing spatial interpolation in broadband signal beamforming, it can reduce the number of antenna elements and corresponding RF modules, A/D converters, etc. It can also eliminate the mutual coupling between antenna elements while getting the narrower main beamwidth and lower sidelobe level.

本文的主要研究工作和贡献如下：●提出了一种基于窄带处理的FH信号盲检测和参数盲估计的实现方法，即首先求出多路信号之间的互相关，进而得到互功率谱密度矩阵，然后通过对CSDM进行对折处理来抑制噪声、定频信号及其他干扰的影响，并将所有属于FH信号的hop(每一跳的驻留时间在时频图上持续的线段)从CSDM中筛选出来，最后用阵列信号处理中的到达方向估计理论在频域中估计出各个hop的方向参数，利用方位信息完成FH信号分离并得到FH信号的数目及其各自的参数集；●提出了一种确定FH信号检测门限的策略，该策略不仅使得检测门限能够通过理论计算得到，而且还显著地抑制了非跳频信号的干扰，从而能有效地检测出FH信号；●提出了一种基于宽带处理的短波FH信号盲检测和参数盲估计的实现方法，即首先利用宽带空间谱测向技术得到接收信号的DOA，然后采用宽带波束形成技术对特定方向进行空间滤波，实现多个信号的分离，最后分别提出了两种FH信号的盲检测和参数盲估计方法，第一种方法适用于空间某个特定方向上存在着几个驻留时间不同的恒跳速FH信号和其他干扰信号的混合信号，第二种方法适用于空间某个特定方向上仅含一个可变跳速的FH信号和噪声的混合信号；●将空间插值的概念和宽带波束形成技术结合起来，提出了一种基于频域处理的宽带恒定束宽的波束形成方法。

Furthermore, the thesis takes the advantage of Chapter Three "The roles' multiple relationship in Ai-Lin Yan's poems" which embraces the three kinds of writing archetypes all above to present the poetic thoughts' orientations with multiple conflicts of individual consciousness by the struggle and the escapement the role "I" treat "you" on the individual consciousness and the performance of the gender in the text, the harmony and the separation "you" treat "I" in the spirit of thinking and on the physical passion, and the metamorphosis of "him" or "her" in accordance with or against subversion "I" treat "him" or "her" that way between the interpretive community and the Other, the imagined community and the alterity.

在当代的文学批评中，相较於对现代小说或现代散文之析论趋势，专文探讨而研究现代诗之论作仍非主流大宗，而居於现代诗中边缘书写的女诗创作，在向来以阳系体制为主导之诗域内，亦往往不易彰显其独特文学价值性。因此，本论文拟择定代表当代台湾女诗中创作思维既有别於他者，亦强烈建立女性意识书写风格之颜艾琳诗作，进行深度剖析，并藉由文本中特殊凸显出之角色个体意识冲突，作为论证台湾九0年代现代女诗突破既往父权文化藩篱，且开启新世代诗创定位之初探基点。

It is a holistic, non-material realm that lies outside of space and time, but upon which we impose the categories of space and time and localisation via the mysterious Kantian categories of our minds.

它是一个神圣的、非物质的领域，位于空间和时间之外。在它之上，通过我们的意识这种神秘的康德式范畴，我们赋予了空间、时间和定域性的概念。

The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.

本文对上述问题做了研究：第一，在数值模拟方面，借助于张涵信提出的NND算法和混合通量法，我们将他建立的时间为一阶、空间为二阶精度的快速隐式算法推广为时间和空间均为二阶精度的算法，这样做保留了原格式收敛快的特点，而且能适用于真实的非定常流态的计算；第二，将张涵信的拓扑分析方法加以推广，研究了涡轴附近及破裂点邻域内流场的空间特征，并以这些拓扑分析结果为指导，研制了一套显示计算结果的软件，这一软件能很好地帮助我们分析流场的计算结果和旋涡演变的特征。

The introduction of quark delocalization can be viewed as taking into account either the contribution of excited configurations or the distortion of individual baryon due to mutual interaction, its characteristic is to allow the six-quark system to choose the favorable configuration by its own dynamics automatically; Various quark models extended linear or quadratic confinement potential for 3q system to 6q system directly. Due to the nonlinearity of QCD, quark-quark interaction in color singlet may be different from that in non-color singlet. For example, the contribution of three-gluon exchange to one baryon is different from that to two baryon singlets, and so on.

引入夸克蜕定域效应，既可以看作是考虑了具有较高能量的激发组态的贡献，也可以看作是考虑了重子不碰撞过程中发生了畸变，其特点是让夸克体系自动选取最有利的组态；以往的QCD模型总是将哈密顿量直接从单重子系统推广到双重子系统，但QCD理论是一个非线性理论，处于色单态的两个夸克间的相互作用可能不同于处于非色单态的两夸克间的相互作用。
