查询词典 supply

The area used to be known as Nacochtank, which was a settlement of Necostan or Anacostan Indians. The Indians lived well there, surviving on an almost endless supply of fish from the river. The first European explorer to visit this area was Captain John Smith in 1608. His visit opened up the area to European settlement along the Anacostia River a few years later.

过去，这个区域较为人所知的名字是 Nacochtank ，它是 Necostan 或 Anacostan 印地安人的定居地；住在这儿的印地安人生活过的很好，他们依这条河内源源不绝的鱼儿维生。1608年时，第一个造访此处的欧洲探险家是约翰史密斯上尉( Captain John Smith ，因其与印地安公主 Pocahontas 的故事而为人所知)，这个地方因他的造访而开启，几年后，欧洲人开始沿着阿纳卡斯蒂亚河创建殖民地。

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.
