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.

结果表明：随着提升管内表观气速的增加，立管内的负压差梯度变化不大；而随着系统循环量的增加，立管内的负压差梯度以及滑移速度均增大；随着加入热解室内松动气量的增加，立管内尤其是立管上部的压力也随之增大，热解室内无论是移动床流动还是流态化流动均对立管的稳定性影响不大；但当热解室内的压力超过某一值时，立管内的料封很快被破坏，导致系统无法运行。

1前言 现有的均热炉计算机控制系统大部分是以燃烧控制为主，即控制炉温、炉压和空燃比等热工参数。这种控制方法由于控制的目标是炉温而不是炉内加热的钢锭，因此，很难实现钢锭优化加热的目的。针对马钢初轧厂的实际生产情况，采用文献【l提供的钢锭一维无限长圆筒在线控制数学

Results: 1. The value of all experimental indexes decreased significantly after heat stress, and reached the lowest at the time 2-8 hours after heat stress. This indicates that the immunity of the mice is damaged to the largest extent at 2-8 hours after heat stress. 2. L-arginine supplementation with appropriate dose could remit the acute atrophying of thymus and spleen tissue caused by heat stress. 3. After L-arginine supplementation with appropriate dose, the lymphocyte proliferation, the level of concentration of IL-2 and * expression of IL-2R raised in the group with room temperature; in the heat stress group the level of three indexs decrease significantly. Furthermore, the decrease of the group given 1 .Smglg.bw L-arginine is the smallest. This result indicates that the concentration of 1 .Smglg.bw L-arginine supplementation could remit the depressment of the immunity caused by heat stress. 4. The [Ca2~] in activated thymocytes of the group with L-arginine -2- supplementation is significantly higher than that of the group with water supplementation. This indicates that L-arginine supplementation could protect thymoeytes of mouse under heat stress. We also found that the fluorescence intensity of [Ca2~] in activated thymocytes of the group given 1 .Smglg.bw L-arginine is the highest.
