In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。

The infrared radiation characteristics of unsymmetrically two dimensional nozzle are experimentally studied. UTDN is designed and manufactured by prolonging one broad side of a general two-dimensional nozzle AR8 and its aspect radio is 8. Temperature distribution on the axes and spectral IR intensity on the orientation of 0, 10, 30, 60 and 90° on three typical detective planes of the hot plume are measured on hot plume simulation platform of the turbo fan engine.

In Chapter One we give the background of large unsymmetric matrix eigenproblems and basic numerical algorithms for solving them. We review the state of the art of this subject. Finally, we describe the work of this thesis. In Chapter Two we make two improvements for the Jacobi-Davidson method combining with the refined projection principle.

This is a properly positioned, nonrotated film as evidenced by (1) comparative anterior ribs equidistant from the pedicles,(2) medial aspects of the clavicles symmetrically positioned,(3) the carina approximates the right pedicles, and (4) no difference in aeration between the two sides.

一张适当位置，非旋转的胸片是通过以下几个方面判断的：（1）从椎骨上比较各前肋之间间距相等，（2）锁骨的内侧面呈对称分布，（3）气管隆凸靠近右侧胸椎，还有（4）两侧的充气影应该是相同的。

The first two impulsions\' influences to the product market environment and capital structure is one-off, once facing the impulsions, the oligopolies will adjust their product and capital decisions, then the equilibrium of product market will recover. When facing the third impulsion, the oligopolies can reach to a temporary equilibrium by adjusting their strategies, but the leader will have a strong desire to change its strtage and the long-term equilibrium will not be reached until one of the oligopolies retreat from the market.

前两种随机冲击对市场环境和资本结构的影响是一次性的，寡头企业在冲击之后调整产品市场决策和资本结构决策，产品市场可以恢复均衡；第三种冲击之后企业可以通过调整策略获得暂时的均衡，但领导企业有进一步作出非对称策略变化的动力，市场的长期均衡是寡头厂商之一退出市场。

As a natural result, the mass matrix is a positive definite consistent and time-independent one, and the two time-dependent and nonsymmetric matrice, that is, the "gyroscopic damping" and "centrifugal stiffness" ones, don't exist in the equation.

在不附加任何&运动学&假设的情况下，作为自然的结果，方程的质量阵是正定、协调的常数阵；方程中不存在两类时变的非对称系数项，即所谓的&陀螺阻尼&项和&离心动刚度&项。

At First, the thesis researches the dynamic characteristic of servo valve, model of dynamical outfit about valve control unsymmetrical hydraulic ram, influence of the additional disturbing force and the systematic static error, on the base of analysis of fatigue testing machine system. Then the mathematical models of position control system and force control system are built. According to the principle of load-matching, the hydraulic dynamical outfit and power source system are designed and components are chosen. Then the correlative parameters of system model are calculated and the simulation study is carried out.
