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.

The rheological character of a polymer often appears as shear-thinning. Most polymers behaviour in a solution can be explained by the polymer chain or hard sphere theory. Other than that, shear-thickening polymer solution also exists. Its behavior can be explained by dilatant theory, which suggests that the shear-thickening of the solution is due to the swelling of the polymer particles. This phenomenon often occurs in suspension or emulsion. Solution exhibits a mixed behavior can also be found whose behavior is such that shear-thinning occurs under low shear force and shear-thickening occurs under high shear force. Under this circumstance, the viscosity versus shear force graph exhibits a spoon shaped curve. The rheological study can be applied to the dispersion of paint which can predict the dispersion effect of various polymer materials in solution.
中文摘要一般高分子聚合物溶液的流变行为多半呈现剪稀(shear-thinning)的现象,而大部分的高分子在溶液中的行为是以分子链或是硬球观点来解释,另外也有剪稠(shear-thickening)现象的高分子溶液,其流变行为则是以膨胀体观点来解释,即在高剪切力下,由於高分子团体积变大而使溶液黏度升高,这在悬伏液、乳液等常见;但也有在低剪切力下,溶液具有剪稀的行为,而在高剪切力下却成现剪稠的行为,在黏度对剪切力作图时,会呈现出一个勾形曲线的图形;流变行为的探讨可应用在涂布材料的分散技术上,以推测不同的高分子溶液对分散效果的影响。

如果用西方哲学的观点,从意念和现象的角度对心外无物进行再诠释,就会发现,王阳明的心外无物有着特殊的含义:物是意念中的物,是认识与物自体的再创造,是存在于人的意识领域的物,是现象界里的物;心是物的存在域,也是物产生的源泉。

Deng's idea of systematic combating corruption terminates the viewpoint that corruption should be regarded as an ideological or interclass conflict; it reveals the importance of combating corruption and accelerates the great change of fighting against power corruption to system corruption.
邓小平提出的制度反腐思想第一次从理论上结束了把腐败现象看作是一种思想作风问题或阶级斗争的表现,深刻揭示了制度反腐的重要性,推动了我国反腐败斗争从权力反腐到制度反腐的重大转变,实现了反腐理论的新飞跃,提出了不搞运动,从建立健全制度入手解决腐败现象的新路子;邓小平提出的:"一手抓改革开放,一手抓惩治腐败"的两手抓思想,使经济建设和廉政建设并重,确保了社会主义现代化事业的顺利进行;邓小平提出的反腐败"还是要靠法制,法制靠得住些"的思想,使廉政建设在社会主义法制的基础上,真正做到"有法可依,有法必依,执法必严,违法必究,"逐步实现了依靠法制和制度而不是人治来解决党风廉政建设的问题。

The Earth possibly is one by occupies the major part material stably the counter-flow inner layer as well as occupies the few parts the counter-flow outer layer to be composed, the former is constitutes the Earth quite stable movement, the attraction, the magnetic field and so on the macroscopic phenomenon foundation; The latter constitutes the Earth most to be rich in the change the beautiful semblance, such as: Land, islands, volcano, earthquake, plate movement and so on nature environment with each kind of great phenomenon, eliminate this this also are decide the Earth for the perfectly round spheroid basic reason, because the internal heat circular reactions is from starts, the huge energy finally becomes the Earth good fortune a beautiful rich life the star.
地球可能是一个由较稳定占绝大部分物质的对流内层以及占较少部分的对流外层组成,前者是构成地球比较稳定的运动、引力、磁场等宏观现象的基础;后者则构成地球最富于变化的美丽外表,诸如:陆地、岛屿、火山、地震、板块运动等等自然界环境与各种伟大的现象,除此这也是决定地球为浑圆球体的根本原因,因为内热循环反应是从一点开始的,巨大的能量最终把地球造化成一颗美丽的富有生命的星球。

Results: 1 Tritiated thymidine incorporation assay showed that 1μM adenosine plus coformycin slightly inhibited CTLL-2 proliferation, while 5-20μM adenosine elicited marked inhibition on CTLL-2 proliferation responded to IL-2 a dose-dependent fashion. 2 Coformycin alone could also inhibit CTLL-2 proliferation at the concentration of 2.5μM. The underlying reason maybe due to the endogenous adenosine produced by CTLL-2 cells.
结果:11μM腺苷对CTLL-2增殖仅有轻微的抑制作用,而5、10、20μM腺苷的存在可显著抑制CTLL-2的增殖,并且呈剂量相关,P值均小于0.05.2CTLL-2经过2.5μM助间型霉素的单独处理也可引起轻度的增殖受抑现象,分析其可能原因是T细胞自身可以分泌腺苷,所以该抑制现象的出现与内源性腺苷有关。3本实验所用腺苷浓度对CTLL-2的活细胞百分率影响轻微。
