热电制冷技术广泛应用于散热、除湿等领域,具有节能环保的优点.针对电器柜的除湿装备效率低下、速率缓慢,严重影响设备的正常运转,对空气温湿度调节机冷端结构进行建模设计以及换热除湿数值分析,重点在翅片结构优化设计,以及进口风速、制冷温度等环境参数控制.结果 表明当入口风速为3 m/s、冷端温度为-15℃时,冷凝器存在最佳结构设计尺寸,即翅片长度420 mm、翅片间距5.6 mm、翅片厚度2 mm,冷凝器能达到湿空气最低含湿量为0.0245 g/kg,进出口最大温差为21.6℃.
交流损耗作为超导电缆本体的主要损耗,其数值大小将影响超导电缆性能及设计长度.使用传统H公式计算CORC电缆损耗时所需时间长、计算复杂.针对以上缺点,提出一种基于有限元仿真软件COMSOL Mul-tiphysics下的T-A公式计算方法,通过对三相同轴超导电缆主要结构参数的设计,并建立稳态下超导电缆电磁场模型.此外,分析了导体层绕制角与电磁损耗之间的变化规律.结果 表明,各相导体层绕制角均为20°情况下电缆本体总电磁损耗为0.203 W/m,满足设计要求.在此基础上,增加各相绕制角均可减少电缆电磁损耗,其
Obligate brood parasitism,which refers to parasitic birds,fish,and insects that lay eggs in host nests,imposes strong selective pressure on hosts because the reproductive output of hosts is reduced consid-erably or eliminated completely while the foster p
Global temperatures are increasing rapidly affecting species globally.Understanding if and how different species can adapt fast enough to keep up with increasing temperatures is of vital import-ance.One mechanism that can accelerate adaptation and promote
Many organisms are characterized by strikingly contrasting black and white coloration,but the function of such contrasts has been inadequately studied.In this article,we tested the function of black and white contrasting plumage in white stork Ciconia cic
Coordination and consensus in collective behavior have attracted a lot of research interest.Although previous studies have investigated the role of compromisers in group consensus,they provide little insight into why compromisers would allow such social a
Patterns of specialization and the structure of interactions between bats and ectoparasitic flies have been studied mostly on non-urban environments and at local scales.Thus,how anthropogen-ic disturbances influence species interactions and network struct
The functions of sexually selected traits are particularly sensitive to changes in the environment because the traits have evolved to in-crease mating success under local environmental conditions(Rosenthal and Stuart-Fox 2012).When environmental condition
Wildlife tourism is a thriving form of nature-based tourism that can provide revenue for conservation funds,and increase public aware-ness of biodiversity conservation (Xiang et al.2011).Tourism,how-ever,may induce behavioral and physiological stress resp
As the only working dog independently developed and bred in China,Chinese Kunming dog (CKD) was approved as a new breed by the Chinese National Livestock and Poultry Genetics Commission in 2007.Now CKD is widely used by the Chinese army and police and has
