摘要：Evapotranspiration(ET)is of great significance for the ecological environment and water resource utilization in arid and semi-arid *** Mongolian Plateau,owing to drought,low rainfall,and extremely uneven distribution of water resources,has a typical temperate continental climate.A refined understanding of the spatiotemporal distribution of ET in this region will help in establishing regulatory strategies for climate change responses,regional livestock regulation,and grassland degradation *** this study,meteorological station data,precipitation data,and the Penman-Monteith model were used to study the temporal and spatial distribution characteristics of actual ET over the Mongolian Plateau from 2011 to *** found that:(1)The spatial distribution of ET in the Mongolian Plateau showed a high trend in the north and east and a low trend in the middle and *** was a significant difference in the regional annual ET,with the highest ET reaching over 500 mm and the lowest being only approximately 70 mm.(2)The annual ET values in 2013,2018,and 2019 were relatively large,varying between 80 and 500 mm,and the overall ET of the Mongolian Plateau first decreased,then increased,and then decreased.(3)The temporal distribution exhibits a unimodal trend of increasing and then decreasing,with July being the turning ***-September was a period of high ET,with the highest ET exceeding 100 *** vegetation coverage was high,precipitation was abundant,and the vegetation ET effect was *** was a period of low ET,with a maximum ET of approximately 10 mm in January and December;the ET for the month with the lowest value was approximately *** quantitative inversion method proposed in this study can provide method and data support for north and central Asia,and other large arid and semi-arid areas.

摘要：We investigate the area and entropy spectra of D-dimensional large Schwarzschild black holes. By utilizing the new physical interpretation of quasinormal mode frequency we find that a large Schwarzschild-AdS black hole has an equally spaced area spectrum and an equidistant entropy spectrum; both are dependent on the spacetime dimension.

摘要：随着社会和行业的发展,互动性公共艺术受到越来越多的关注和欢迎。然而,就地铁公共艺术而言,由于空间和功能上的局限性,将互动公共艺术引入地铁空间有着来自于各方面的限制和难度。本文试从互动性公共艺术本身的特征和地铁空间对公共艺术的要求两个方面,探究互动性公共艺术介入地铁空间的可行性和方法原则。

摘要：随着时代的发展,人们开始追求高品质生活,而能够满足这一需求的软装设计行业开始崭露头角。社会对软装设计人才的需求量增大,多数院校环境设计等相关专业为此开设了软装饰设计课程。随着信息技术的崛起,对《室内软装饰》这门实践性核心课程的改革逐渐深入,在混合式教学下,为当前教改提供延续性创新新思路,但未能充分调动学生的积极性。笔者将Groupproject(简研讨式)教学方式运用到课堂中,通过这种教学方式提升学生的学习能力。软装设计热潮的兴起,直接反映了当下人们对生活品质及精神面的强烈追求。

摘要：广告作为中国近现代社会历史语境中的短期印刷品——"蜉蝣",以其文字与图像的丰富性、复杂性和多样性为研究者提供了很多有价值的学术问题,而当前的信息化时代所带来的媒介变革、数字技术、大量数字化的历史资料及相关的研究成果也为广告研究提供了新的条件和可能。中国商业广告数据库(Chinese Commercial Advertisement Archive,简称CCAA)即为其中的个案。CCAA收集和数字化了中国近现代五份代表报纸的外国商品广告,对这些广告的内容(文字和图像)进行元数据化,免费对公众开放,以期能为对中国近现代这一特定历史时期内的广告、报纸、历史、社会、文化和思想感兴趣的学者提供图像资源,搭建一个知识共享、交流和再生产的平台。而通过对CCAA个案的研究,关注数字档案化广告过程,从对数字技术和数字媒介的反思出发,对该过程中引发的一系列理论问题——广告的蜉蝣性、广告中图像与文本的关系、图像与元数据的关系,图像元数据化与视觉知识生产等——进行讨论和阐释,为我们当下再认识与研究广告以及档案库相关问题提供新的知识、角度和方法。
