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 responses on animals (Maréchal 2015;Beehner and Bergman 2017).Part of the physiological stress response is increased activity of the hypothalam-ic-pituitary-adrenal (HPA) axis,resulting in the systemic elevation of glucocorticoids.An increase of glucocorticoids in the blood-stream leads to rapid mobilization of stored energy reserves and inhibitions of nonimmediately critical activities like growth,repro-duction,and digestion in response to environmental challenges(Beehner and Bergman 2017).Although there is a debate as to whether deleterious chronic stress exists in wild populations(Beehner and Bergman 2017),measuring glucocorticoids is an im-portant tool in assessing anthropogenic disturbance to animals(Maréchal 2015;Palme 2019).Cortisol,the main glucocorticoid secreted in primates,is metabolized by the liver and partly excreted in urine,meaning that elevations of cortisol and its metabolites pro-duced in the stress response can be detected by using urine (Palme 2019).

不同波纹参数对波纹管的传热性能有重要的影响,因此开展波纹参数的优化设计研究具有重要的意义.通过建立不同参数波纹管有限元模型,数值仿真研究了雷诺数为10000 ～40000时波纹组合类型及凸凹波纹宽度比例对流动及传热性能的影响规律.研究结果表明,相比单一的凸起或凹坑波纹,凹坑-凸起及凸起-凹坑组合波纹能诱导更强的流体混合继而更大程度地提高波纹管的传热性能.此外,当组合波纹的凸起与凹坑波纹比例等于或小于1时波纹管有更优的流动及传热性能.研究结果可以为波纹参数的优化设计提供指导.
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

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
