Many researchers have devoted their work to the development of modal analysis extraction techniques in order to obtain more reliable identification of the modal parameters. There are many damping identification methods, but each one has different merit and defect. In order to find which one is the most reliable method with respect to certain characteristics, this thesis focus on how to identify structure's damping in time domain. The following works have been done in this thesis: 1. Investigate four modal analysis methods——the LSCE Method, the Ibrahim Time Domain Method, the Time Domain Collectivity Modal Parameter Method, the Rational Fraction Polynomial Method and improve on the ITD Method in arithmetic.

本文主要做了如下工作： 1、集中研究了四种常用的模态识别方法，即最小二乘复指数法、Ibrahim时域法、时域总体模态参数辨识法及有理分式多项式法，并对ITD法在算法上进行了一定的改进； 2、建立结构动力模型，利用这四种方法在具体条件下识别结构的阻尼，并绘制相应的图； 3、讨论不同的情况下，不同的识别方法对阻尼识别精确性的影响； 4、基于业已明确的阻尼识别的精确性，根据研究的需要，指出在实际的识别过程中，如何选择最佳的识别方法以及识别过程中需要注意的问题； 5、选择最为精确的阻尼识别方法，以导师李书进教授在日本京都大学防灾研究所强震反应实验室所做的一足尺木制结构房屋的动力测试实验为实测模型，识别其阻尼； 6、在本文的最后，尽作者所知，提出了一些需要改进的地方，并对未来的研究方向给出了作者的建议。

This paper explores improving the relativity of accountancy information from two aspects : the first is upgrading the current financial report system , for which the author proposes that part of items in the current financial statements should be improved and relevant statements such as overall income statememt should be included ; the second is upgrading the current financial analysis method , including development of du pont analysis method and revisal of wale proportion analysis method , for which the author proposes that attention should be paid to the financial analysis , meanwhile enhance analysis of unfinancial index , establish banlance marl record and a set of efficient evaluation system by applying synthetic grade - point method

本论文从两个方面探索提高会计信息的相关性，一是对现行财务报告体系的改进，提出应改进现有报表的部分项目，并增加全面收益表等相关的报表；二是对现行财务分析方法的改进，包括对杜邦分析方法的衍展及沃尔比重分析法的修正，提出应在重视财务分析的同时加强非财务指标的分析，建立平衡记分卡，运用综合评分法建立一套高效的绩效评价体系。

In order to improve the existing generic service oriented intrusion tolerant system in aspect of architecture and function, this paper presents an improved adaptive intrusion tolerant system with improved architecture, functional modules and key techniques. From an overall consideration of the system, mixed with firewall, intrusion detection and other traditional technologies, IAITS combines redundancy, diversity and various fault tolerant techniques, thus enhancing reliability through active replication and secure multicast, reaching tradeoff between system complexity and intrusion tolerance ability by redundant design only in most vulnerable components, and supporting data protection on the basis of architecture with only a little extra cost in software and hardware by making use of topological coherence between application servers group and key share servers group.

An improved shceme for the old double-way authentication access control scheme based on Harns digital signature is proposed. The new double-way authentication protocol of the improved access control scheme can prevent man-in-the-middle attack and replay attack. After strict formal analysis with BAN logic, the result have proved that the authentication protocol is secure. The improved access control scheme is realized by the mode of single-key-lock-pair. Under new access control scheme, user can own several kinds of access right upon one file under the new scheme without the supposition that the access rights is increase by degrees, and the possibility of overflow problem is significantly reduced by our new method
