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.

Firstly, we hypothesize that the stocks of funds with net outflow will have a higher herding measure when the fund manager is concerned with his reputation risk (Scharfstein and Stein, 1990), and have a lower herding measure when he engages in gaming the incentive scheme derived from the asymmetric performance-flow relation. The results support the reputation-risk hypothesis.
首先,针对前期流量与基金群集指标的关系,本研究推论:如果经理人行为符合声誉风险假说(Scharfstein and Stein, 1990),则前期净流出基金的群集指标会高於前期净流入基金的群集指标;反之,如果经理人行为符合放手一博假说,则净流出基金的群集指标低於净流入基金的群集指标,实证结果符合声誉风险假说。

The use of footscan balance test system of national high-level pistol, rifle shooters had a balance of stability tests, by analyzing the following major conclusions: First, all the athletes in men's pistol shooting athletes body posture and adjusting the balance of stability the capacity of the worst; the second, firing only state body sway eyes open area and before and after the shaking smaller decrease; and thirdly, the general balance of the stability of indicators (both before and after the body center of gravity, around shaking rate, trajectory length, shaking the area) can not accurately reflect the high level of shooting athletes balance the characteristics of stability, and derived indicators - per unit area of the track length (the total length of track and shaking the area ratio), both show the balance of stability, but also reflect the attitude adjustment ability, in the sway area certain circumstances, the greater its value, indicating that ability to regulate the more intense the frequency of shaking sooner, the better the stability of physical balance, in the actual shooting of firearms at the time of the impact of the smaller, can be used as shooting athletes evaluation and selection of indicators.
运用footscan balance测试系统对国家高水平手枪、步枪射击运动员进行了平衡稳定性的测试,通过分析得出以下主要结论:第一,所有射击运动员中男子手枪运动员身体姿态的平衡稳定性及调节能力最差;第二,射击训练只能使睁眼状态下身体晃动面积和前后晃动幅度减小;第三,一般平衡稳定性指标(身体重心前后、左右晃动幅度、轨迹长度、晃动面积)不能准确地反映高水平射击运动员平衡稳定性的特点,而派生指标——单位面积的轨迹长度(轨迹总长度与晃动面积的比值),既显示平衡稳定性,又能体现姿态调节能力,在晃动面积一定的情况下,其值越大,表明调节能力越强,晃动的频率越快,身体平衡稳定性越好,在实射时对枪支的影响越小,可作为射击运动员的评价和选材指标。
