Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.

由于信元抖动的复杂性，非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能，以及在目的节点的源定时恢复问题作了较为全面的研究。首先，文中描述了CBR业务流的信元抖动，并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后，采用了精确的数学模型和分析方法，有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法，在性能分析中，我们成功地完成了CBR业务流信元抖动的功率谱分析，使得不但可以从频域定性地认识信元抖动的能量分布特性，而且还可以定量地求出信元抖动的均方根值(rms：root-mean-square)，以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中，我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流，并基于这一模型进行了CBR业务流中间节点的初步排队分析。

In this study, the methodology of linear structural rela- tionship model of latent variable has been studied which is the first time in China. Some extended conclusions have been come up to, such as multi-factor congeneric measure model, the reliability of measurable variable and its hy- pothesis test, the relation between standardized solution and unstandardized solution, multidimensional path model with measure errors, and multilevel model of latent vari- able. Some examples have been shown to help apply these results in practice, such as the analyses of the children growth-development data, the bone density data and the health resources data by means of latent variable model. Not only have new explanations for these data been achieved, but also powerful patterns for applying the theoretical methods in medical sciences and other fields.

日常叙事的风行是对曾经一统天下的宏伟叙事的偏执性反拔，是启蒙神话破裂之后的幻灭叙事，写物主义倾向和日常生活本身的封闭性与重复性使小说的主体性呈现为碎片状态；模糊审美作为叙事风格主要表现为内心光照逐渐黯淡的黑夜主题夺走了叙事者的存在基础，欲望化叙事和表象化叙事闪现着一种遗忘意志，作家相对主义式的犹豫表达模糊了必要的价值分野；小说的新闻化倾向作为一种文体现象，是对快速推进的信息时代和全球性的非虚构化潮流的文化回应，但它所标榜的真实性因为只能停留在表浅层次而显得暖昧和可疑；自我重复是反修辞和反诗学的命题，是指相同的叙事成分在同一作家的不同作品中的机械重复，自我重复有细节重复、情节与结构重复、扩写与改写等表现形式，媒体时代的强制性文化法则、作家的内在缺陷和叙事模式的局限性是其文化根源；反讽与讽刺相比，是一种相对温和却又更具普遍性的文化反抗形式，但九十年代小说的言语反讽、情境反讽和总体反讽都因为主体缺乏内在的价值支撑而陷入虚无，虚伪的反抗成为一种遮蔽现实的屏障；九十年代小说的叙事视角从传统的全知视角转向限知视角，具体表现为旁观视角和窥视视角，这种强调局部性和差异性的视角本来可以成为扩展个人话语空间的正当途径，但由于它们被过分地利用于渲染感官刺激和心理刺激，与大众趣味不谋而合。

The thesis probes into Schoenberg' thinkings about music history, music nationalism, music education, music criticism, and music creation, respectively. There are some important viewpoints in Schoenberg's music thought: Firstly, Schoenberg's ideas of music history, he believes relationship of tradition and revolution in art is dialectical in nature, and argues that evolution in music was determined by natural law, obviously influenced by Hegel's philosophical history idea. Secondly, the thesis sums up his viewpoints of music nationalism, such as "lay stress on art music, look down on folk music","lay stress on western European music, look down on non- western European music" by Schoenberg's account about the reasons of the formation of national art, the dominant of national art and nationality in music; in fact, this viewpoint of western cultural centricity is one of his i mportant viewpoints throughout his life; Thirdly, Schoenberg's concept of music education: in his thought a composing teacher should teach the students how to master "the tool of art", train them for their ability of "one major and various kinds of techniques", try his best to nourish the student's personality; Fourthly, Schoenberg set forth some opinions about modern music critics and the method of music criticism: a music critic must be equipped with the quality of a music expert, and render composer's idea to the public by his art imagination, but not his personal opinion,and Schoenberg stress the areas of music criticism on style and idea ; Lastly, Schoenberg's concept of music creation: Expressionism and organism are two important issues in Schoenberg's thinking about music creation.

本文通过对勋伯格各类论文、书信、演讲、专著等文稿的评述，分别探讨了作为音乐思想家的勋柏格的音乐历史观、民族主义音乐观、音乐教育观、音乐批评观与音乐刨作观，并在此基础上总结了折射在勋柏格音乐思想中的几个重要观点：一，勋柏格对于音乐历史的认识：通过德奥音乐界前辈给予他的创作启示，以及勋伯格对自己几个创作阶段的发展历程的总结，阐述了他对于艺术中的传统与革新之间的关系的辩证认识，并通过这些问题总结出音乐的演进与黑格尔倡导的&历史发展必然性&哲学观念之间存在着必然联系；二，勋柏格的民族主义音乐观：通过勋柏格对于形成民族艺术特征的根本原因、民族艺术中的支配现象、民间音乐与艺术音乐之间的比较、音乐刨作中的&民族性&问题的意识等方面问题的剖析与认识，总结了他的&重艺术音乐，轻民间音乐&、&重西欧音乐，轻非西欧音乐&的观点，从而突出了他的精神领域中的根深蒂固的&德奥音乐中心论&，这是一个浸润着浓厚的西欧文化中心论色彩的观点，也是贯串他毕生的音乐思想的重要观点之一；三，勋柏格对音乐教育问题的见解：勋柏格认为作曲教师应该教会学生掌握&艺术的工具&、在教学中努力做到&一专多能&、注重个性培养；四，勋柏格对当代音乐批评家与音乐批评方法提出的要求：音乐批评家必须具备作为一名音乐家的专业修养，要以真实、客观的态度对待音乐批评这门神圣的职业，充分运用内心的艺术联想向公众再现作曲家的意图，而不是将个人见解强加于受众；同时，批评家需要对艺术的过去与未来拥有全面的了解与较准确的预测，在音乐批评的具体范畴中，应将重心角度置于探讨音乐作品的风格与思想之间的关系方面。

Hydrolysis of the mischarged amino acids in theediting reaction will rely on the proper binding and correct recognition of both mainchain and side chain of the substrate. In general, the editing active site ofLeuRS-ED has a very rigid structure with a defined stereochemistry and usesa number of conserved residues to precisely bind and recognize the misactivatedamino acids and discriminate and reject the cognate amino acid, specifically usingMet336, Asp345, and possibly Thr247 for main-chain recognition and Thr252,Met336, and Val338 for side-chain recognition.

In this chapter,on the base of discussingcomprehensively the three subjects of the Adversary Principle,andcombining with the practice of the reform of the civil trial style,thewriter holds that the non-binding Adversary Principle that is beingpracticed for the time being in our country is not the Adversary Principleof its essence,and it should be changed to be the binding standard to boththe court and the parties.On this,the writer have given the followingdefinite suggestions:First,the parties' claim acts should be controlledunder the law,and cannot be exercised for the objectives of delaying theproceedings or raising the action cost,otherwise will suffer losing hisright,or will be punished economically;Second,in order to reflectthe fairness of the action,and prevent the delay of the process,in thecivil procedure field of our country the timely evidence producism shouldbe carried out and implemented,and the evidence-production deadlinesystem should also be set up.Furthermore,to the parties that produceevidence out of time,hewill be deprived of attack and defense,orwill be given certain economic sanctions; Third,scientific admissionsystem should be set up,and to the admission withdrawal or statementscontradictory to the admission,should give legal restrictions orprohibitions.

本章中，作者在全面论述辩论原则三大命题的基础上，结合我国民事审判方式改革的实践，认为我国目前推行的非约束性辩论原则并非本质意义上的辩论原则，应将其转变为对法院和当事人的约束性规范原则，并在此基础上提出了如下具体建议：第一，当事人主张行为应受法律控制，不得以拖延诉讼、增加诉讼成本等为目的予以实施，否则将遭受失权效或经济上的诉讼制裁；第二，为体现诉讼公平，防止诉讼迟延，在我国民事诉讼领域应当推行和贯彻证据的适时提出主义，设置具有法律后果的举证时效制度，并对当事人违反举证时效制度的提供证据行为采取或取消其攻击防御方法，或课以其一定经济性制裁的惩罚措施；第三，设定科学的自认制度，对撤销自认或与自认相抵触的陈述应给予法律上的限制或禁止。
