The development of Chinese ceramics culminated during the Song dynasty. At this time, exquisite celadon works emerged, such as Ru Guan celadon and Southern Song dynasty official kiln celadon, which exhibited the glory of their era. Since the excavation of Zhanggongxiang kiln celadon in Ruzhou city, Henan province, China, it has been attracting widespread scholarly attention at home and abroad. Most scholars have suggested that Zhanggongxiang is the official kiln of the Northern Song dynasty. In this paper, taking the celadon unearthed from the Zhanggongxiang kiln as a sample, the combination of laser Raman spectrum and thermal expansion methods is used to study the inheritance relationship between Zhanggongxiang celadon and Ru Guan celadon in the firing process. Meanwhile, the rationality of using Raman Ip value to evaluate the firing temperature of ceramics is reviewed. The main conclusions are as follows. First, the firing temperature of Zhanggongxiang celadon with various glaze colours is quite different, whereas the firing temperature of the same glaze colour is similar, thereby inheriting the firing technology of Ru Guan porcelain. Second, the Ip value of glaze cannot evaluate the firing temperature of porcelain with similar firing temperature. The Ip value corresponds to a range, within which it does not fully conform to the rule that the larger the Ip value, the higher the firing temperature. The Ip value is also associated with the formulation in addition to firing temperature. It is applicable to evaluating porcelains with a similar formulation but a large temperature difference.  相似文献

This article examines the transfer of creative industries as a policy idea to Lithuania. Tracing the stages of the transfer and analysing its consequences in the local cultural policy field, this paper argues for the importance of studying cultural policy process. The findings reveal that the process of the international transfer of creative industries mattered, because it generated wider transformations in cultural policy field by having ambiguous effects on local power relations. The policy idea of creative industries opened the cultural policy field to new actors. As a result, competition for scarce state funding increased, but cultural organisations gained access to the European Union structural funds. In all, creative industries as a policy idea significantly transformed Lithuanian state cultural policy, in that it led to a reassessment of both the practices and identities of cultural organisations.  相似文献

AUTHOR, N. &; AUTHOR, P. December 2017. Article title. Alcheringa 42, 301-305. ISSN 0311-5518. Dysagrionidae are common in Paleogene sedimentary rocks, but rarely recorded in the Mesozoic. This family, however, is diverse in Burmese amber. A new dysagrionid damselfly, Palaeodysagrion youlini Zheng, Chang &; Chang sp. nov., is described here based on a well-preserved specimen (holotype) in Burmese amber. The new damselfly provides wing apex and body characters for Palaeodysagrion. It differs from Palaeodysagrion cretacia in having Arc slightly distal of Ax2, the midfork slightly basal of the nodus, Cr and Sn almost perpendicular to RA and RP and in having a simple wing system. This is the fourth dysagrionid damselfly described from the Burmese amber.

Spatial planning using a landscape approach has been recognized as being essential for reconciling ecological, cultural and socio-economic dimensions in sustainable development (SuD). Although embraced as a concept, there is a lack of planning tools capable of incorporating multi-level, multifunctional and multi-sectoral perspectives, especially in a rural context. The departure point in this paper is the legal requirements for municipal comprehensive planning (MCP) in Sweden and an e-mail survey about incentives, stakeholder involvement, policy integration and implementation in MCP in all 15 Swedish mountain municipalities. The purpose of this explorative study is to examine whether MCP could be a tool in planning for SuD. Results indicate a general lack of resources and a low status of MCP that affect, and even limit, stakeholder involvement, policy integration and implementation. However, legal requirements for MCP are targeted at SuD, and municipal personnel responsible for planning appreciate the potential of MCP. Therefore, there is potential to develop the MCP into an effective landscape planning tool. To accomplish this, the status of an active planning process has to be raised, the mandate of the local planning agency has to be secured, and residents and land users have to be involved throughout the planning process.  相似文献

本文通过将郾客铜量与楚简文字对比,认为郾客铜量中的"■"字当隶定为"■",读为"故",并将包山68号简释为"耆州"的"耆"字改释为"■",此字可能为楚文字中"故"的专字,进而对郾客铜量铭文中仍存在的问题加以探讨,以待考古学的进一步求证。  相似文献

A new species of Aboilinae (Orthoptera: Prophalangopsidae), Aboilus perbellus, is described and illustrated based on three well-preserved forewings recovered from the Middle–Upper Jurassic Daohugou beds of Inner Mongolia, China. The new species differs from all congeneric forms in its special forewing coloration and features of its wing venation. To date, three types of forewing coloration have been found among different species of Aboilus at Daohugou, suggesting that these taxa inhabited different ecotopes.  相似文献

Liu, Q., Zhang, H.C., Wang, B., Fang, Y., Zheng, D.R., Zhang, Q. & Jarzembowski, E.A., 2014. A new saucrosmylid lacewing (Insecta, Neuroptera) from the Middle Jurassic of Daohugou, Inner Mongolia, China. Alcheringa 38. ISSN 0311-5518.

A new genus and new species of Saucrosmylidae (Insecta, Neuroptera) are described (Daohugosmylus castus) based on a well-preserved hindwing from the Middle Jurassic of Daohugou, Inner Mongolia, China. Daohugosmylus gen. nov. is distinguished by a large and nearly semi-circular hindwing, relatively wide R1 space possessing several rows of cells, anteriorly bent Rs, dense crossveins over the entire wing, and smooth outer margin.

An efficient and simplified plane beam-column joint model that can describe the strength deterioration, stiffness degradation, and pinching effect was developed for the nonlinear analysis of non-seismically detailed reinforced concrete frames. The proposed beam-column joint model is a super-element consisting of eight spring components and one panel zone component, representing the bond-slip mechanism of the longitudinal reinforcement and the shear deformation mechanism of the joint concrete core region, respectively. In order to represent the dynamic response at the system level, the elastic constitutive law is applied to the eight connector springs, while the Bouc-Wen-Baber-Noori (BWBN) model is adopted to describe the hysteretic behavior of the panel zone component. For the implementation of the finite element analysis, the algorithmically consistent tangent of the BWBN model is derived as a uni-axial constitutive model, while the initial stiffness of the panel zone component is determined by the concrete compression strut assumption. The accuracy and efficiency of the proposed beam-column joint model were calibrated at both the component and structural levels by comparing the simulated results with the experimental data for non-seismically detailed joint sub-assemblages and a reinforced concrete plane frame.  相似文献

清代中外西藏阿里的自然地理知识初探   总被引:1,自引:0,他引:1  
清代西藏阿里地区虽然与中原内地相距绝远,然而在清代前期中央国家的积极努力之下,中原内地对阿里的自然地理知识的获得取得了相当大的成就,尤其是对阿里地区的名山大川的分布及其详情在感性认识层面上达到了相当的高度,然而这种势态没能继续发展下去,从清代中后期开始,这一热情逐渐消退,相关的自然地理知识增长缓慢。另一方面,从清代中后期开始,西方殖民者和探险家进入西藏,对阿里地区进行了一系列的近代地理学的勘测和总结,世人所知的阿里自然地理知识有了迅速发展,形成了一系列丰富的内容。本文拟以清代中原地区的官私著作和西方探险家的考察报告、游记等材料,重现清代西藏阿里自然地理知识的累积过程和发展水平。  相似文献
