无线网络深度覆盖技术在石窟寺保护利用中的运用——以敦煌莫高窟为例

针对莫高窟在保护利用数据传输过程中出现的问题与发展趋势,提出了利用无线网络深度覆盖技术构建数据传输平台,解决莫高窟大型洞窟内保护利用数据无法传输的问题。为构建实用性强的传输平台,采取了如下措施。首先,针对莫高窟保护利用各项业务数据采集、传输模式、传输机制等各阶段特点,提出了基于无线网络深度覆盖技术构建数据传输试验平台的需求;其次,设计了试验平台构建方案,依据莫高窟洞窟分布与建筑形制确定了试验平台构建位置。结合莫高窟目前无线网络覆盖现状,通过选型分析确定了无线网络深度覆盖关键技术,并应用该技术构建试验平台;最后,对试验平台无线信号覆盖范围、信号强度、传输性能、安全性等进行验证,确保数据传输的完整性与连续性。此试验平台已运行一年有余,应用效果良好。     

佛教美术中的维摩诘题材释读

维摩诘题材是中国佛教美术中最为重要且常见的题材之一。早在佛教东渐之初的两汉时期,以维摩诘为主角的《维摩诘经》已经被介绍来中国,伴随经典的翻译传播,维摩诘所代表的融通世、出世间,注重理、行不二的大乘佛教理念在中国寻得了大众,特别是具有儒家传统而兼出世情怀的士大夫阶层的普遍认可,而经中表述的丰富多彩的情节与生动鲜明的形象更使得维摩诘成为远自魏晋以来,广及绘画、雕塑以及诗歌、戏剧、音乐等各个艺术门类的重要题材[1],这使得它在中国文化发展史上的作用,甚至超出了其于宗教范畴内的意义。本文拟就维摩诘作为美术题材的发生、发展及其通例表现形式的宗教蕴意作通览性的考察与探究。     

吉林省城市体系等级规模结构研究

等级规模结构是城市体系的三大结构之一,其特征可以反映出城市在不同规模层次中的分布状况及城市人口集中或分散的程度,有助于认识城市体系发展所处的阶段。通过统计数据计算分析,运用分形理论,发现吉林省城市体系等级规模结构满足位序-规模分布规律,城市规模分布的均衡程度较高,中小城市比较发育,首位城市垄断作用不突出,缺乏大城市。在吉林省城市体系动态变化过程中,等级规模结构相对稳定且不断趋于集中。在此基础上提出重点培育通化、延吉等大城市;继续扩大长春规模,发挥整体效益;加强交通网络建设;加快矿业城市可持续发展等建议。     

I.m. Sechenov: the patriarch of Russian physiology

Using quotations from Russian (e.g., Mechnikov and Pavlov) and western European (e.g., Ludwig) sources of his friends and colleagues, as well as from his autobiography, this paper describes the life and personality of Ivan Mikhailovich Sechenov (1829-1905), who became well known because of his central inhibition theory (1862). He trained in several European centers, including Vienna, were he worked with Carl Ludwig (1816-1895), with whom he corresponded for several decades.     

The fluidity of nationalistic and ethnic aspirations in Aceh

ABSTRACT. Peace negotiations between the Indonesian government and the Free Aceh Movement (GAM) have resulted in the signing of the Memorandum of Understanding (MoU) ultimately ending a three‐decade‐long struggle for independence. Through a historical comparative analysis, this article explores the changing nature of Acehnese nationalism. It explores how Acehnese ethnicity and nationalism are constructed and how they have transformed over the decades in conflict with the Indonesian government. Acehnese ethnicity and nationalism, which are political in nature and ethnic in character, have ideologically shifted throughout time. Historical junctures and myths were utilised to legitimise these changing ideological goals. Despite the transformation of Acehnese nationalism and consequent changes in its ideological basis, a strong Acehnese identity still remains a constant.     

基于HSI彩色模型灰度分量的宁夏岩画断代研究初探

岩画是古代先民生产、生活、祭祀等活动的生动记载,是人类文明的史诗,岩画的断代一直是岩画研究的难点,文中提出了一种基于色度、饱和度和灰度(HSI)彩色模型的数字图像处理技术提取岩画灰度值(I)的方法,利用岩画灰度值与岩画作画年代之间的线性可比关系,测定岩画的年代。此方法能提取整个岩画中的灰度值,避免了手工提取有限个点的缺陷。试验结果表明此方法能为岩画的断代提供一种可参考的、简便的、快速的计算机解决方法,但测定年代的准确性依赖于选取的岩画标尺年代的准确性。     

梁启超的公私观

对于公私问题的思考和论述是梁启超思想中重要的组成部分。梁启超对公私观的理论重构,是承袭传统与汲取西方文化的成果。他批判了中国传统的公私观,对"公"、"私"的内涵进行了转化,从"朝廷为公"向"国家为公"转化,从"群体之私"向"个体之私"转化。由此,把公私的主体转化为"国家"与"国民"。在此框架下,从道德、政治、经济、法律等不同视域,对公私规范进行了重构与解释。他把中国传统的"公私对立"观念转化为公私相互依存;他区分了政治法则与伦理道德,使传统的"公"、"私"观念在政治学说层面上具备了近代形态;他还强调国民的权利及其对国家的责任。梁启超的公私观对中国当时及其后的公私秩序的讨论产生了不可忽视的影响。     

L.A. Orbeli - outstanding physiologist and science leader of the twentieth century

L.A. Orbeli and his school developed new directions in physiology: evolutionary physiology, the theory of adaptational-trophic functions of the sympathetic nervous system, the theory of coordination of functions, and neuroendocrine regulations in the body. Orbeli enriched the study of the physiology of the cerebellum, the sensory organs, the kidneys, and the study of pain. His name is associated with the development of the foundation of physiology of extreme states (the physiology of deep-sea exploration, high altitude, and high velocity flight).
