Positive and negative interval divisions of dynamic pressure signal was proposed. The differences of weighted signal sums,signal mean values,signal peaks of every two successive intervals were selected as the features of leak signal,and their calculations and relative scaling transformations were presented. The feasibility criteria for lengthwise and breadthwise evaluation of leak signal features were presented,and evaluation was done with features extracted from field data and the feasibility was verified.

Based on the date of outcrop, log and lithology, sequence stratigraphic division and correlation were made on Neopaleozoic in south of North China Basin, and high-precision geologic correlation framework was built up in the basin.2. In the term of sedimentary features of Neopaleozoic in south of North China Basin, lateral variation of sedimentary facies was studied selectively in Benxi-Taiyuan Formation, Shanxi Formation, Lower Shihezi Formation, Upper Shihezi Formation and Shiqianfeng Formation. Lithofacies paleographic features and the sedimentary evolutionary process of Late Paleozoic in south of North China Basin were worked also.3. On the basis of sand-bodies Isopach figure drawing, the distribution of major reservoir sand-bodies of Neopaleozoic in south of North China Basin was studied. Basing on the distribution of sand-bodies in sequence stratigraphic framework, combining the development and distribution features of barrier and underwater distributary channel, there is a disquisition on the distribution regularity of pay reservoir sand-bodies of Neopaleozoic in this area.

以露头、测井和岩性资料为基础，对华北盆地南部上古生界进行了层序地层的划分与对比工作，建立了盆地范围内的高精度地层对比格架。2、根据华北盆地南部上古生界的沉积特点，按本溪组—太原组、山西组、下石盒子组、上石盒子组和石千峰组5个层组分别开展了沉积相的横向变化对比研究，并以此为基础探讨了华北盆地南部晚古生代的岩相古地理特征及其沉积演化过程。3、以编制砂体等厚图的方式研究了华北盆地南部上古生界主要储集砂体的平面展布规律，并以层序地层格架下的砂体展布研究为基础，从沉积体系控制下的砂体分布特点出发，结合障壁岛与水下分流河道的发育与分布特点，系统深入地开展了区内上古生界有利储集砂体的分布规律研究。

The conditional nature of the distribution over label sequence can depend on non-independent, interacting features of the observation sequence. CRFs offer a solution to the problems in Chinese shallow parsing with hidden Markov models or with maximum entropy Markov models. First, as HMMs are generative, it is hard to employ overlapping features and nonindependent features of the inputs such as surrounding words.

通过单个状态将增大的或减小的概率和传递到它们的后继状态，使得这个单一的分布不需要对每个状态进行归一化，整个状态序列可以一起描述，从而克服了HMMs和 MEMMs的标记偏差（1abel bias）问题，而标记偏差的问题在汉语浅层分析中是个严重的问题。

The paper is composed of three main parts."Part of Drama" focuses on analyzing contents and artistic features of Shakespere"s drama "Othello";"Part of Opera" aims at illuminating contents and artistic features of Verdi"s opera-"Otello";"Part of Comparision"is the key part of the essay. The author tries to explore differences and causes by comparing Verdis opera with the original on the point of artistic features and contents.

全文分为三部分，第一部分&戏剧篇&意在分析莎士比亚戏剧《奥瑟罗》的主题内容和艺术特点；第二部分&歌剧篇&旨在阐明威尔第歌剧《奥瑟罗》的主题内容和艺术特点；第三部分&比较篇&是本文的研究重点，笔者致力于歌剧与原著在艺术特点和艺术内涵上的比较研究，探讨二者之异同及其原因。

It is necessary to distinguish between the typical features and variable features in the research on the phonetical features of Min dialects, so that we can recognize the synthetical and subordinate characteristics of Min through grasping the origin and development of this dialect.

研究闽语的语音特点，有必要区分典型特点与变异特点，这样有助于更好地把握闽语的源和流，体现闽语的综合特征和下位特征。

The history and current situation of research in speech recognition are proposed all-sidedly and systematically. We probe into such topics about acoustic features, phonetic features, phonologic features and auditory perception in terms of related theory and disciplines. Furthermore, we summarize and analyze focus in current theoretical and technical aspects of speech recognition and immediately put an insight into challenge to speech recognition presently, even in a long time.

论文全面、系统地介绍了国内外语音识别的发展历史和发展现状，结合相关学科的知识，分析了语音声学特征、语音学特征、音系学特征及其语音感知等有关问题，分析并总结了目前语音识别理论和技术实现方面的研究重点以及目前、甚至在相当长的时期内语音识别面临的挑战。

According to the analysis of features of the key outcrop sequence stratigraphy, build the sequence frame, through the section comparison, and the study of feature of the 5 key outcrops, then it can be concluded that, conglomerate on the denudation plane or the other contrastive sediment are the main features surrounding the bottom border of the sequence. In the foreland basin sediment environment, the transilient group of mud rock and sandstone are the main sediment features of low-stand system tract. Thick mud rock and sandstone interbedded is the chief component of transgressive system tract, sometimes together with thick turbidity current sandstone; High-stand system tract is composed by the combination of mud rock and sandstone interbedded, with the progradation as its main style. Maximum flooding surface Sediment are usually mudstone, and the thickness is different from each other.
