Two Taiwan-based economists estimate the technology content of exports by the machinebuilding industry of the East Asia region during 2004-2008, using comparative analysis to clarify changes in the relative competitiveness of four East Asian nations (China, Japan, South Korea, and Taiwan) accompanying the formation of a regional trading bloc and production networks. In particular, they examine the technology content of these countries' machinebuilding sub-industries' exports within the Southeast Asian market (documenting the rise of the machinebuilding industry in China) as well as the penetration of Japanese, South Korean, and Taiwanese sub-industries into China's market. The results point to areas of emerging competition among China, South Korea, Japan, and Taiwan for East Asian markets, which can only be expected to intensify in the future.

我国考古和文物保护工作中物探技术的应用 总被引:7,自引:0,他引:7
钟世航 《文物保护与考古科学》2004,16(3):58-64
20世纪80年代以来,物探技术在考古和物保护方面应用越来越多,在古墓探查、大型古建筑地下遗存现状探查、重要古建基础状况探查、古遗迹断代等方面,地球物理技术都找到了发挥作用的机会。本通过地球物理技术在云冈石窟、龙门石窟、克孜尔石窟、北京故宫紫禁城、嵩岳寺塔、古泗州城遗址、风阳明中都等的物理探查实例,以及查找古墓、古遗迹断代等方面的工作,介绍了我国在考古和物保护领域应用地球物理技术的进展,并指出了物探在用于考古和保时的特点和展望。 相似文献

运用科学技术方法对清代珐琅的研究 总被引:4,自引:0,他引:4
作者运用原子发射光谱、扫描电子显微镜、偏光显微镜和金相显微镜,对故宫博物院藏清代珐琅残片进行了实验分析。研究中.对构成珐琅的硅酸盐材料、铜材料、焊接材料以及镀金层的元素组成进行了测试;对珐琅残片断面的焊接层和镀金层的微观形貌、焊接层的金相组织进行了观察和鉴别。在此基础上,运用结晶学、矿物学、金属学和金相学的基础理论对珐琅原料种类、各种原料的作用、珐琅料的熔制与烧蓝、铜材料与焊接材料的合金属性、焊层的金相组织、掐丝珐琅的烧制工艺等问题加以探讨,试图藉现代科技手段揭示清代珐琅所包含的科学技术内涵。 相似文献

Modern technology lends itself to holistic exploration and widely accessible outreach. New technology allows scientists studying
our planet either from space or deep under the seas, to explore and reveal both natural and cultural resources that have previously
escaped our scrutiny. However, the use of these new technologies is expensive and often the exclusive tool of industrial research.
Yet, these new technologies can lead the way to greater collaboration, better science and more public access. In 2003 and
2004, a landmark project, combining government agencies, industrial technology and outreach set new standards in collaborative
scientific exploration. The project focused on six shipwrecks at depth in the Gulf of Mexico. The questions posed by the project
illuminate how science and industry can collaborate to produce remarkable results. The papers presented in this issue form
a model for deepwater exploration. 相似文献

Skill is central to the identification of the individual within lithic analysis. Modern replication tends to focus on the
proficient flintknapper, and emphasises complex, technically demanding implements and high quality raw materials. Yet, acquiring
lithic skill is a universal process that manifests itself in various ways depending on technological strategy and raw material.
This paper presents the results of a programme of experimental replication that explores notions of consistency and identity.
Based on Mesolithic blade technology, using direct percussion reduction and variable pebble resources, it compares knappers
with different experience and identifies some salient parameters of individual performance. 相似文献

The archaeological record of Oldowan hominins represents a diverse behavioral system. It has been suggested that exploitation of lithic resources by Oldowan hominins was simplistic and represented mostly use of local sources of stone. Here we investigate the raw material selection and transport behaviors of Oldowan hominins reflected in the stone artifact assemblages from the Kanjera South Formation, South Rachuonyo District, Kenya. Using geochemical methods (ED-XRF) artifacts are linked to primary and secondary source outcrops throughout southwestern Kenya. These data show that hominins selected raw materials for transport at frequencies that are significantly different from their availability on ancient landscapes. Furthermore, a substantial proportion of the assemblage represents transport over relatively long distances (>10 km). Our study further suggests that in the early stages of stone tool use hominins used a wide variety of raw materials and selected these materials at some distance from their eventual discard locations. Early hominin behavior may have incorporated an understanding of raw material source distributions across a more extensive landscape than has been previously documented. This supports the growing perspective that Oldowan technology represents a more complex behavioral pattern than is usually associated with the beginnings of hominin tool use. 相似文献

可持续发展文化是科学与人文融合的必然选择 总被引:1,自引:0,他引:1
“科学”与“人文”的关系表现为“分立”与“融合”,二者的分立所导致的严重后果直接表现为科技的异化和人类价值观的扭曲,间接导致了生态环境的极度恶化和日益严重的生态危机,不利于人类社会的可持续发展。从科学与人文分立的历史追溯,发现既有科学对人文的压制,又有人文对科学的反抗。随着全球性生态危机的日益凸现,科学与人文的融合是必然选择,这既是理论发展的趋势又是现实的要求。可持续发展文化融合了科学与人文的内涵,体现了人文关怀,营造了“科技人性化”发展的氛围。科学与人文必将伴随着可持续发展文化的发展而不断融合。 相似文献
