实际情况如何

According to the actual situation and performance requirements, we found that how to bate the influence of friction in the system is the principal difficulty for us to improve stabilization accuracy.

If marketing is partly about creating and managing expectations, Mr Bidwell now has an estimated 45m annual visitors to London attractions who will be all too able to compare any green claims made for the city against the reality.

绿色使命与实际问题如果说营销活动的部分目标是要创造和利用预期，那么，面对伦敦每年吸引到的估计4500万游客，比德韦尔先生如何应对他们的预期将是个巨大挑战，因为这些游客有太多机会将这座城市的绿色宣言与现实情况加以对比。

Through fine-tuning the unit-price combination, it could solve 2 problems that almost all contractors concern about during the tendering period: one is how to decrease the offer, and hence increase the winning probability with the expected payoff un-changed, while the other is how to invisibly raise the profit value when the offer keeps invariant.

它通过调整单价组合，能够解决承包商在实际投标时最为关心的，在预期利润不减少时如何降低报价，以提高中标率，以及在报价基本不变时，如何无形提高预期利润增值两种情况。

Now high schools have two main tasks: propaedeutic to enter a higher school and propaedeutic to take up an occupation after graduation. So how should we adjust and enrich various resources according to the spirit of the reform in the whole country and local schools and in terms of the history、tradition and current situation of schools? And how to change the style of administration on new curriculum during the process of carrying it out in order to adapt to the requirement for the setting-up and implementation of new curriculum? It is really a big challenge for the stabilization and innovation of schools.

如何按照国家和地方课程改革的精神，根据学校的历史传统和现实情况的实际，调整和充实各种教育资源，合理地设置国家课程和学校课程，构建符合课程改革要求并具有学校鲜明特色的课程体系，以及在实施新课程的过程中如何适当地改革课程管理方式以适应课程设置与实施的要求，都对承担着升学预备教育和就业预备教育双重任务的普通高中提出了巨大的挑战，对高中学校的稳定、创新与发展提出了严峻的考验。

To be sure, we get into what are, at first, rather strange circumstantialities——but how can they be avoided, if our radicalness is not to remain an empty gesture but is to become an actual deed ? Let us go on then with patience.

确实，在一开始我们进入到相当奇怪的情况里：如果我们的彻底性不至于仅仅是一种空洞的姿态，而是要成为实际的行为/操作『deed』，那么，我们要如何才能够避免这种情况呢？

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。

First is the definition, ruction and development of corporate culture.Second is to analyse the culture of DLYPA. Last but not least is to suggest the methods of constructing the culture of the company.

文章首先列出企业文化的内涵、作用及该理论的发展现状，然后分析青少年刊社的企业文化发展情况，理论结合实际，从而进一步分析刊社应该如何建设企业文化。

On this base, in serval special instances, this thesis also research how to improve GM(1,1) model and make grey forecasting more better accordly with practical applications.

在此基础上，本文接着研究了在几种特殊情况下，如何对GM(1，1)模型进行改进，从而使灰色预测更好的符合实际应用。

In the case of scarce practical data and priori knowledge,modeling of the transmission loss of HF skywave to give guidance to the practical system is a very difficult problem in communication countermeasure simulation system.

如何在实际数据和先验知识较少的情况下，建立适用于通信对抗仿真系统的短波天波传输损耗计算模型来为实际系统提供指导，是通信对抗仿真中一个非常棘手的问题。

But it can only be used when each of evidence is independent, in practical applications there are many evidences can not satisfy this condition, so how to improve this theory has become to a focus problem; More over, multi source information fusion needs data of multi platform, so how to unify data of multi platform to the same time space so as to fuse is an important factor influencing the performance of fusion.

但D-S理论只适用于证据独立的情况，实际应用中往往需要处理不独立的情况，因此对证据理论的研究和改进是摆在众多学者面前的一个重点问题；另外，多源信息融合要利用多平台信息，如何将各传感器信息统一到同一的时间空间范围内进行融合是关系到融合性能的一个重要因素。
