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.

However, we only knew that Le2 involves "change of states", may provide speech time as a reference time, and has many pragmatic functions. In this paper, based on its core semantic content- Current relevance and anteriority, we aim to define Le2 as a perfect marker, and it also introduces a perfect time span.

Math-genius-and-artist had no time to build his geometric sculptures, so thatAndy couldn't pursue his fascination with well-made knives and guns, so that Krisand Chris and Rick and Young didn't have enough time to read, so that Shira—aher outstanding chorale group if she missed any homework assignments.

这些活动浪费了孩子们的时间和精力，以至于John，这位在数学上有天赋的小艺术家，没有时间去构建自己的几何雕塑品；Andy没有时间用来专研其制作精良的刀和枪； Chris、Rick和Young没有足够的时间花在阅读上；为了完成作业任务，充满才气的演员与富有天赋的音乐家的Shira不得不放弃自己在圣歌唱诗团里卓越的表现。

Based on the results, suggestions are provided to assist engineers in this field to select best parameters for saving test time of flash memories.

就NOR型的快闪记忆体测试来说，本研究发现，在相同测试条件下，随著IC电源电压升高可以减少测试时间，因为电压越高则写入与擦拭的动作会越快完成，且测试项目中最为费时的就是写入时间；提高测试频率也可以减少测试时间，因为较高的频率加快测试指令下达的速度与资料传输的时间，对於减少读取与写入的时间有极大的帮助。
