Overpressure in the Malay Basin and prediction methods

Predrill overpressure prediction is important for well planning and migration modeling for prospect evaluation. The Eaton (Journal of Petroleum Technology, 24 , 1972, 929) and Bowers (SPE Drilling & Completion, 10 , 1995, 89) methods are used worldwide for postdrill overpressure prediction using sonic log and predrill overpressure prediction using seismic interval velocity. In this research, these two methods were used for overpressure prediction using 3D anisotropic prestack depth‐migrated seismic interval velocity in a field of the Malay Basin. In the shallow overpressured zone, where the mechanism of overpressure is undercompaction, the onset of overpressure was predicted reasonably well using the Eaton and Bowers methods with their standard parameters (i.e., Eaton exponent 3 and Bowers loading curve) for seismic velocity. However, in the deep overpressured zone, where fluid expansion is the cause of overpressure generation, these methods underpredicted the high overpressure. In the deep overpressured zone, the overpressures were better predicted by applying a correction to the Eaton method. On the other hand, the Bowers unloading parameters for the fluid expansion mechanisms did not show any significant effect on overpressure prediction. Hence, in the study area, the Bowers method is not effective for 3D overpressure prediction using seismic velocity, whereas the Eaton method is more robust and can be used for 3D overpressure prediction from seismic velocity.     

水域景观美学价值评价理论研究

水域景观是自然风景的重要组成部分。美学价值是人类审美和水域景观联系的纽带。水域景观美学价值的评价是天然水资源成为景观水资源(旅游资源)的先决条件,美学价值的高低直接影响水域景观的观赏质量,它是水域景观旅游价值评价的重要内容。本文首先根据人类神经生理、心理学等学科的研究成果探讨人类审美的主观缘源;再重点剖析水域景观的美学特征;最后提出水域景观美学价值评价的理论。     

Informal markets and global value chains – the disembedding of Romanian dairy smallholders

The Romanian dairy-farming sector is marked by subsistence and semi-subsistence farms. Through consolidation in the retail and dairy sector, the price pressure has moved toward producers of raw milk. Through new European, national and private standards and global actors tapping into the Romanian market this development is reinforced. At the same time, the smallholders, formerly accepted to be acting on an informal level, cannot access their main distribution channels anymore. Additionally, through several legal constraints being developed since Romania’s accession to the European Union, the smallholders are neither able to issue invoices, nor to access certain subsidy programmes as they are not considered juridical persons. This article focuses on the consequences of this disembedding of farmers. The peasants are pushed toward informal activities or value chain positions, in which they do not have any bargaining power with the globally sourcing intermediaries they are supplying. The contemporary approaches of global value chains and global production networks build the theoretical framework for the study. Here it is argued that informal markets must be included into these approaches more concisely.     

对剩余价值范畴的重新界定

传统政治经济学对剩余价值范畴的定义在其存在的条件、来源和剩余价值的分配等方面均过于狭窄,且界定时采用了非经济的标准,这既有悖于马克思的有关论述,也与当前的实际情况不完全吻合.本文以马克思的有关经典论述为依据,并结合经济生活的实际,对传统剩余价值范畴进行深入思考,以澄清人们的模糊认识.     

旅游产业部门结构合理性的SSM分析-以陕西省为例

为了寻求省域旅游产业发展的合理部门结构,利用偏离-份额分析法,以旅游统计年鉴提供的数据为基础,对陕西省旅游创汇部门的产业结构进行实证分析。研究表明陕西省各旅游创汇产业部门中,原有基础好,竞争力较强、具有部门优势的增长部门包括商品销售、邮电通讯和市政交通等部门;原有基础差但发展快,竞争力较好,具备一定部门优势的增长部门包括住宿、餐饮业等;基础较好,但竞争力较差的部门则包括长途交通运输业、观光游览、娱乐业等。论文针对各部门实际发展状况分别进行了分析,指出各自发展方向和策略。最后评价了偏离-份额分析法在旅游创汇部门产业结构分析中的应用效果,认为该方法具有较强的综合性和动态性,能够有效揭示旅游创汇各部门产业结构变化的原因和发展机制,是确定未来旅游业创汇部门发展主导方向的有效方法之一。     

景德镇御窑遗址出土青花绣墩的考古修复新方法研究

景德镇御窑遗址出土的15世纪中叶青花方胜纹绣墩,体量较大,器形特殊,出土时破损和缺失严重,修复难度较大。本研究通过分析传统考古修复中石膏作为补配材料的局限性,利用3D扫描打印的优势,设计采用新颖的高强度透明树脂取代传统修复补缺材料,并且结合特制的加固装置完成对大型青花绣墩的考古修复,满足了后期研究与展览的需要。本研究提出了具有一定实践意义的3D打印补配大件异形陶瓷器的修复技术路线。     

比较视野下中国乡村认知的再辨析:当代价值与乡村复兴

本文首先探讨了西方社会对乡村认知转型的基本思潮,其演进脉络经历了生产主义、后生产主义和多功能乡村三个阶段。在此基础上,本文尝试建立了从主体和功能两个维度进行乡村认知的基本框架,并从历史视角对中国乡村的认知变迁进行了回溯。新中国成立以来,对于乡村的认知大致经历了牺牲型乡村和追赶型乡村两个阶段,直至城乡统筹的概念提出,才有一定的改变。本文提出了当前中国乡村的三重价值——乡村的农业价值、乡村的腹地价值和乡村的家园价值。基于这样的多元价值,尝试性地提出了"乡村复兴"的概念框架。     

论国家侵权精神损害赔偿制度的确立——由佘祥林“杀妻”案所引发的思考

当前对《国家赔偿法》的修订已纳入立法规划,结合佘祥林“杀妻”一案,针对目前国家赔偿法中有关国家侵权赔偿的范围仅包括实际的物质损失,而不包括由于侵权造成的精神损害,本文提出应扩大国家侵权赔偿的范围,将国家侵权造成的精神损害纳入赔偿之列,逐步建立起完整的国家侵权赔偿制度,才能真正满足构建法制社会的要求。     

牛肃《纪闻》及其史料价值探讨

牛肃所撰《纪闻》系唐代第一部小说集,所记多开元、天宝时事。原书大约宋以后亡佚,惟《太平广记》、《太平寰宇记》等存有120余条。《纪闻》中的人物传记、僧侣传记、鬼怪幽冥故事等对盛唐时期的社会生活、政治事件等多有直接反映,其中一些材料还为《新唐书》、《资治通鉴》、《宋高僧传》等所采用,故而具有极高的史料价值。
