The main work and the originality points of this dissertation could be concluded as the following parts:(1) To analyze systematically the mathematical model of LES of air flow in great space, under the case of isothermal and non-isothermal, as well as the combined action of buoyancy and strain. Some basic problems are studied about the LES application into airflow simulation of great space, such as boundary conditions, spatial difference scheme and time advancing scheme, time step etc., which creates the basis for the LES application to indoor airflow simulation.(2) Both the instantaneous and time averaged flow field of great space with multiple jets under isothermal and non-isothermal cases are explored with large eddy simulation method, and also discussed the dynamic characteristics and the law of fluidflow in the great space.(3) Based on the results of LES of the great space and the Fanger thermal comfort indexes, it is brought forward the concept of the series of dynamic thermal comfort evaluating indexes, which could be divided into thermal comfort index with time averaged properties PD, PPD, PMV, thermal comfort index with instantaneous properties IPD, IPPD, IPMV, and time averaged thermal comfort indexes TAPD, TAPPD, TAPMV, and transient situations time averaged thermal comfort indexes TTAPD, TTAPPD, TTAPMV. The differences among them and the calculation methods are discussed, and the four kinds of indexes are calculated with the thermal comfort index PD as an example.(4) Based on the LES results it is discussed the hot air stratification phenomena in air-conditioned buildings in the case with air supply and return registers on the ceiling and the case on the sidewall. The fundamentals of the hot air stratification are studied and the relations of estimating hot air stratification are brought forward.(5) With the advanced apparatus such as hot wire film anemometer IFA300 and laser particle field anemoscope, corresponding model test and site measurements have been done, which are compared with the simulation results and LES is proved a very promising method in air flow simulation indoor.

本文主要工作既创新点体现在以下几个方面：(1)系统分析了等温、非等温和考虑剪切力与浮升力综合作用的高大空间大涡模拟数学模型，并研究了高大空间大涡模拟在室内气流仿真应用中的一些基本问题，如边界条件、空间离散格式和时间推进格式、时间步长选择等问题，为大涡模拟在室内气流计算中的广泛应用打下了基础；(2)首次用大涡模拟方法研究了高雷诺数下高大空间多射流在等温、非等温情况下的瞬时流场和时均流场分布，并探讨了多射流流场的动态特性和流动规律；(3)基于大涡模拟的动态仿真结果和Fanger的热舒适指标，首次系统地提出了动态热舒适评价指标体系的概念：即基于时间平均参数的热舒适指标PD、PPD、PMV；基于瞬时参数的瞬时热指标IPD、IPPD、IPMV；基于时间平均热舒适指标TAPD、TAPPD、TAPMV；以及沿行动迹线的时间平均热舒适指标TTAPD、TTAPPD、TTAPMV，并分析了四类热舒适指标的差异性和计算方法，还以PD值为例对四类指标分别进行了计算；(4)基于数十种工况下空调房间大涡模拟的结果，研究了空调建筑上送上回和侧送侧回两种情况下热分层现象，并探讨了热分层的基本规律，首次提出了避免热分层现象的判断公式；(5)在暖通空调领域，首次使用IFA300热线风速仪、激光粒子速度场仪等先进设备，完成了与大涡模拟相对应的模型试验，并把实测结果与仿真结果进行了对比，说明LES在室内气流仿真方面是一种很有前景的方法。

Look on the net, fizzle out eventually day of not negative a person with high aspirations and determination, was found by him eventually he thinks at that time good cheap space is Www.vip5944.com then here, I also had persuaded him not to buy the space over there at that time, there are a lot of people to had bought a space over on the net, say the space over there very rubbish, but he is not obedient,still want to buy, the friend won't be bought at that time, I try to do a difficult job as best one can did sth for sb, at that time I that friend says to buy two, a space uses the privacy network that makes him himself like, a space uses the fortune-telling network that makes his like.

就在网上看啊，终于黄天不负有心人，终于被他找到了当时他认为又好又便宜的空间那就是www.vip5944.com这里，我当时也劝过他别买那里的空间，在网上有很多人在那里买过空间，都说那里的空间很垃圾，可是他不听话还是要买，朋友当时不会购买，我就勉为其难代劳了，当时我那个朋友说买两个，一个空间用来做他自己喜欢的隐私网，一个空间用来做自己喜欢的算命网。

The transition of well-arrayed sculptures from a plane form to the present stereoscopic model represents the instantaneous flashes of so-called time-space art, which is full of symbolic implications and visual impact.

看到这些作品，给人的第一感觉是相当富有意味。

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。

His paintings possess a traceable thread within modern art. For instance, Morandi's world is expressed through isolated fragments. In Balthus' world, humans seem to drift, frozen in modern time space, and this kind of language can be traced back to Dutch paintings and great masters like van Dyck.

他的绘画在现代艺术之中存在着一条可以寻找的线索，譬如，在莫兰迪那里，世界是以孤立的片段感来显示的，在巴尔蒂斯那里，人物仿佛都是游离、静止在现实时空之中，而这种语言还可以追溯到尼德兰绘画以及凡·代克那样的古典绘画大师那里。
