The Qinghai-Tibet Plateau stratigraphic region is divided into seven stratigraphic sub-regions: the West Kunlun-Karakorum, AltunQilian Mountains, Qaidam-Hehuang, East Kunlun-Bayan Har, Qiangtang, East Xizang-West Yunnan-West Sichuan, and Gangdise-Himalayan sub-regions. This paper briefly describes the lithostratigraphic units of the seven stratigraphic sub-regions of the Qinghai-Tibet Plateau. According to the lithostratigraphic sequence and its sedimentary characteristics, stratigraphic contact relationship, formation age, and evolution of the biota in each stratigraphic sub-region, the Quaternary tectonic paleogeographic evolution of the Qinghai-Tibet Plateau is divided into four stages.(1) The inherited differential uplift stage since the Pliocene(2.6–1.8/1.5 Ma): the regional sedimentary differences were significant, and the stratigraphic distribution was limited,the alluvial-proluvial sandy conglomerate was widely developed along the piedmont, and fluvial and lacustrine deposits were developed in the low-lying areas between the mountains.(2) The mountain range flattening stage(1.8/1.5–1.2/0.8 Ma): the erosion u

随着沉浸式体验技术的广泛运用,如何通过虚拟空间提升传统非遗文化的传播效用成为社会各界关注的问题。本研究基于列斐伏尔的“空间三元论”对非遗虚拟空间生产问题进行探讨,关注其中各空间生产要素对于非遗文化认同、文化自信的影响。本研究通过2×2×2组间实验(N=209)发现:非遗虚拟情境下空间生产体验具有具身性,空间真实度和参与度有助于提升非遗虚拟空间生产体验的传播效用;非遗虚拟场域下空间表征的效用是有条件的,非遗虚拟空间真实度和文化度的叠加才能对非遗文化认同产生影响;虚拟空间生产体验中VR信息素养具有部分效用:体验者的VR信息素养影响非遗虚拟空间真实度体验的效用,但不影响非遗虚拟空间参与度的效用。

中国对外传播存在触达度低、持续性短、需求复杂、传播低效、认同度弱等难题。数字文化产业可承担文化出海、文化强国的重要使命,是塑造国家形象的重要途径。数字文化产业具有鲜明的国际化特性:国际化“语言”、大众化“融入”、触发式“动情”、自发式“创作”。基于此,本文提出数字文化产业对外传播PMIAI模型,即从感知(perception)、激励(motivation)、兴趣(interest)、行为(action)、认同(identity)五个要素来增强国家形象塑造的可见性,再塑中国与世界的价值主张与沟通情境,强化对外传播效能。

在抖音等短视频平台中,沉寂已久的非物质文化遗产内容获得了大量年轻人的关注。基于媒介丰富度理论、社会认同理论,采用问卷调查法(N=517)、访谈法探索了非遗短视频媒介丰富度、中华民族认同感、文化智力和父母学历水平对青少年文化自信的影响机制。研究发现:(1)非遗短视频表达方式丰富度、信息质量丰富度均正向影响青少年文化自信。信息内容丰富度能够通过中华民族认同感这一中介变量正向影响青少年文化自信。(2)中华民族认同感是非遗短视频媒介丰富度对青少年文化自信产生影响的重要中介。(3)文化智力水平正向调节非遗短视频媒介丰富度对中华民族认同感的影响。(4)父母学历水平正向调节青少年中华民族认同感对文化自信的影响。研究从平台、内容和社会教育角度提出了建议,为研究非遗短视频传播效果、青少年文化自信的影响因素和机制提供了可借鉴的视角和思路。

在过渡区内,关于纳米颗粒曳力计算及输运特性的研究较为困难,通常会采用一些近似方法,将自由分子区或者连续介质区的理论计算式进行修正,以适用于过渡区,但是其准确性值得商榷.本文基于分子动力学模拟方法,研究了过渡区内纳米颗粒的曳力特性,并与相关理论进行对比.结果表明,气-固分子间相互作用对纳米颗粒的曳力具有显著影响.当气固结合强度较弱时,理论计算结果与分子动力学模拟值吻合较好;当气固结合强度较强时,分子动力学模拟结果明显大于理论值,这是由于气体分子在纳米颗粒表面的吸附所导致.基于气体分子在颗粒表面的吸附特性,提出引入有效颗粒半径修正,其过渡区内曳力的理论计算结果与分子动力学模拟结果吻合较好.
