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.

Go up first 2 when, attend Chinese class one day, came an exercitation teacher, at that time sit last me, from the back also sit with respect to my person, when beautiful female teacher turns around to write on blackboard, I see she is wearing a tight white pants, appear a bit, because she is wearing very small very small briefs, so I look see her one most buttock, at that time my JJ can'ts help rose, see more afflictive more, see classmates be in finally absorption attend a lecture, at that time I draw out my JJ to play with respect to big courage, my eye also is staring at the teacher's buttock to look all the time of course, when I am about to shoot, the teacher comes around come over, but I do not have a canal, reckon she also loses sight of me, I continue again all the time, at that time the teacher halted, the eye looks at me:"Backmost classmate, what are you playing?"

上初2的时候，有一天上语文课，来了一个实习老师，当时我是坐最后一排的，后面也就我一个人坐，当漂亮的女老师转过去在黑板上写字的时候，我看见她穿着一件紧身的白裤子，有点透，因为她穿着一个很小很小的内裤，所以我看的见她一大半屁股，这时候我的JJ不由自主的起来了，越看越难受，最后看看同学们都在专心听课，这时候我就大着胆子掏出我的JJ玩起来，我的眼睛当然也一直盯着老师的屁股看，我快要射的时候，老师转来过来，但是我没有管，估计她也看不见我，我一直再继续，这时候老师停住了，眼睛看着我："最后面的同学，你在玩什么？"

Effects of dry temperature and dry time on properties of heat cured sand and the relationship with binder composition are as follows:sands bonded by binders that are not modified have high strength when dry temperature is high and dry time is long,but their anti-wettability power is poor . Sands bonded by binders that are modified by B but not modified by M can be dried quickly and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M but not modified by B can also be dried quickly to obtain maximum strength,then the strength becomes lower when they are dried continually for more time. and sand strength is high but anti-wettability power is also poor. Sands bonded by binders that are modified by M as well as by B at the same time can be dried quickly to obtain maximum strength at low temperature and short time. But the anti-wettability of sand mold is best when they are dried at high temperature and long time.

烘干温度和烘干时间对热硬砂性能的影响及其与粘结剂改性的关系是：未经改性剂B和改性剂M改性的粘结剂砂，脱水速度较慢，烘干温度越高，时间越长，则硬化强度也越高，但未经改性的粘结剂热硬砂的抗吸湿性较差；经改性剂B而不经改性剂M改性的粘结剂热硬砂，烘干硬化速度较快，强度也高，但在高湿度下的抗吸湿性不好；经改性剂M改性而不经改性剂B改性的粘结剂热硬砂，烘干时强度先随烘干时间升高至最大值后，继续烘干时强度又出现下降；经改性剂B和经改性剂M共同改性的粘结剂热硬砂能在短时间和较低的烘干温度下就可烘干到最高强度，即烘干脱水的速度较快，但试样的抗吸湿性差，若在更高温度和更长时间下烘干，试样的抗吸湿性得到改善，综合考虑烘干强度和抗吸湿性要求，对于φ30×30mm试样，理想的烘干温度是200℃，烘干时间20分钟。

Leifeng Pagoda was first built in Northern Song Dynasty 977 AD, two years of peace and rejuvenating the country, originally for the King of Wu and Yue Feng Qian-shu Tibetan Buddhism as a relic to pray for peace and prosperity Luo Ji-fat built, the original name of Princess tower, tower of brick-wood structure leifeng well-known high tower, and Chinese folk legend of White Snake widespread myth is closely related to the story in the embodiment of white snake Bai Suzhen have been a result of the pursuit of true feelings and sea monk imprisoned in Leifeng Pagoda, the Leifeng Pagoda and therefore the statement of history far and wide Leifeng Pagoda on the fire hit twice, the first declared in the Northern Song Dynasty and years, because of Fang La uprising, a torch outside the wooden structure burned to the tower to the Southern Song Dynasty years, have been rebuilt Leifeng Pagoda, West Lake, one of Dusk is the leifeng circulated Leifeng Pagoda at that time subjected to fire the second Jiajing in the Ming Dynasty, when the pirates violation of Hangzhou, Leifeng Pagoda burnt again, remaining tower stands on the shore of West Lake, this case continued until the end of the Qing, Leifeng Pagoda finally collapsed due to overwhelming cause of the collapse on the Leifeng Pagoda in history is also very controversial, in general there are two versions of the previous two years in the clean-up sites Leifeng Pagoda time, found that a considerable portion of the tower of brick side of a small hole in the cave there are Buddhist in the past, people have incorrectly relay erroneous messages will pass into a gold brick by brick, the tower blocks have take-home, resulting in the collapse of the tower argument argument, one of the two, due south is the land of plenty since ancient times, but Hangzhou is the House of silk and tea, the history of Hangzhou on the rich silk, and every year when the silkworms cocoon silk, a variety of reasons, tend to have a large number of cocoon death, Over the past superstition, misconception that cocoon cursed, while the Leifeng Pagoda is a town of white snake demon, thinking that would be the Pagoda bricks at home, they can withstand the erosion of Yao Xie, you have to take a sericulture, his family wealth take a course of time, in particular, Taki shaft damage due to the common people, coupled with those in power are indifferent Leifeng Pagoda finally at 13:40 on September 25, 1924 came crashing down

雷峰塔初建于北宋太平兴国二年公元977年，原本为吴越国王钱淑为奉藏佛螺髻发舍利子以祈祷国泰民安所建，原名叫皇妃塔，塔为砖木结构雷峰塔的知名度之高，与中国民间广泛流传的神话传说白蛇传密切相关，故事中白蛇的化身白素贞因追求人间真情而被法海和尚囚禁于雷峰塔下，雷峰塔因而声明远播历史上的雷峰塔曾两次遭遇大火，第一次是在北宋宣和年间，因方腊起义，一把火把外面的木结构塔身加以焚毁到了南宋年间，曾重修雷峰塔，西湖十景之一的雷峰夕照就是在那个时候流传的雷峰塔第二次遭受火烧是在明朝的嘉靖年间，当时倭寇侵犯杭州，雷峰塔再次把火焚，仅剩塔身屹立于西湖之滨这种情形一直持续到清末民初，雷峰塔终因不堪重负而倒塌了关于雷峰塔倒塌的原因，历史上也很有争论，一般来讲有两种说法，前两年在清理雷峰塔遗址的时候，发现有相当一部分的塔砖一侧有一个小洞，在洞里有佛经而在过去，老百姓们以讹传讹将经砖传成金砖，纷纷将塔砖拿回家，从而导致塔的倒塌此说法之一说法之二，由于江南自古就是鱼米之乡，而杭州又是丝茶之府，历史上的杭州就盛产丝绸，而每年蚕宝宝吐丝结茧之时由于多种原因，往往有大量的蚕茧死亡，过去的人迷信，误以为蚕茧中了邪，而雷峰塔是镇妖的白蛇，以为将雷峰塔的砖放在家里，就可以抵挡妖邪的侵蚀，你家养蚕拿一块，他家求财拿一块，久而久之，塔身特别是塔基由于老百姓的破坏，加上当权者的漠不关心，雷峰塔终于在1924年9月25日下午1点40分轰然倒塌
