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。

A bstract: This paper focus on virtual instrument design of modal parameters identification with curve fitting theory based on rational fraction orthogonal polynomials. Using Forsythe orthogonal polynomials solves the coefficient equation instead of normal power polynomials in order to decrease the morbidity of it, making the orders of coefficient equation reduce to half and increasing computing efficiency.

本文基于有理分式正交多项式曲线拟合理论对振动系统的模态参数辨识进行了虚拟仪器的设计，为了减少系数矩阵的病态，采用 Forsythe 正交多项式代替普通的幂多项式进行求解，使系数矩阵阶次降低近一半，提高了运算速度。

The rhetorical narrative theory combines the precise survey of narrative-mode and the focus on the narrative receiving-context, especially on the reading ethic and ideology, the aesthetic studying of internal text and the social history environment, which is out of the text. It notices reciprocal and communal function of writer, text and reader in the movable course of narrating.

修辞性叙事理论将严谨的叙事形式考察与对叙事接受语境，特别是阅读伦理、意识形态的关注结合起来，将文本内部的形式审美研究与文本外的社会历史环境结合起来，注重作者、文本和读者在叙事的动态进程中的互动和协同作用。

Although these three aspects all face their own difficulties to deepen the influences, the author lastly propose an optimistic legal feminism that does not focus on law's social effect or law's power to social change but on the reflexibility and possibility of prompt responses of legal feminism for social problems.

这三个面向使得作为法律继受国家的台湾，得以逐渐取得某程度的规范主体性，但也出现一些新的问题，亟待社会各界的努力。这问题包括法理重新建构的困难、法治推动的各方阻力、以及法意识上的落差。最后作者总结从法律多元主义的观点，提出一个乐观的女性主义法学，希冀从规范的「法社会创造」之观点，重新评价女性主义立法行动的积极意义。
