自然伽马能谱测井谱解析方法研究

自然伽马能谱测井是重要的核测井方法之一，其地面信息处理系统的关键是实测谱解析技术。低分辨率是自然伽马能谱测井仪的固有弱点，且测井过程中信噪比较低，造成测井置信度不高。从自然伽马能谱测井原理出发，通过中海油实验数据处理后获得的放射性核素的标准计数率谱，对自然伽马能谱测井4种传统数据处理方法的优劣进行了对比，初步探讨了将灵敏度高、空间分辨率好的直接解调方法移植到自然伽马能谱测井谱解析中，为自然伽马能谱测井谱解析方法的选择提供了依据。     

WEB PAGES, AUTHORS AND AUDIENCES: The meaning of a mouse click

One popular framework for analysing web pages has been to think of them as identity performances on the part of the author. This framework opens up possibilities for analysis of the ways in which identity performances are composed. The personal web pages to which this perspective is most immediately applicable, are, however, now only a small proportion of the overall amount of information available on the World Wide Web. It would be possible, by extension, to analyse institutional web pages as performances of the institutional identity. It is the contention of this paper that to do so is to miss out on some important aspects of web page design: namely that the production of a web page involves understandings not only of the audience for the page but also of the capacities of the technology. In addition, web page production has to become a socially meaningful act for the individual web page developer and the institution concerned. It is, therefore, argued that the analysis of web pages can usefully learn from media studies and the sociology of technology in this respect. An interview-based study of the developers of web pages for the service departments of a UK university is described. The ideas of audience which the authors use are far from homogeneous: they include an institutional offline audience for the page, a pre-existing imagined audience, developers themselves as audience, and the technology of the browser as a stand-in audience. The audience and the capacities of the technology are developed in context through the practices of designers.     

奥巴马就职演说辞的隐喻特色解读

认知语言学认为隐喻不仅是一种语言现象,更是人类的思维方式,认知的有力工具。对奥巴马就职演说辞中的隐喻特色,其潜在意图和做出隐喻选择的内在原因进行解读具有十分重要的意义,利于人们进一步了解隐喻的作用和实质。     

自然人性与社会人性的“战斗”——解读克洛德自然人性的复归

克洛德的自然人性，宛若“天使”，在黑暗的“魔鬼”生活中熠熠发光。可是在压抑中复归的人性是畸形的，以至于克洛德用这种不健全的、变态的人性既伤害了他人，又毁灭了自己，终于给自己的一生画上了一个悲凉而凄惨的句号。他既是罪恶的社会和宗教的代言体，又是受害体。宗教禁锢人性的本质不言而喻。

论教育对二战后日本经济崛起的促进作用

二战后,日本经济已濒临崩溃的边缘,但不到30年,就以惊人的速度迅速崛起,成为经济大国,其中很重要的一个原因就是教育为国家培养了一大批经济发展所需要的优秀人才.     

二战时期的中美友谊

二战时期反对共同的敌人,是中美友谊关系的基础。太平洋战争爆发后,中美两国共同抗击法西斯势力,成了一条战壕的战友,以血肉凝成的中美两国人民的友谊迅速升华。对于美国支持的中国抗战,中共也曾表示感谢。史迪威、陈纳德是二战时期中美友谊的体现者和历史见证人。     

古代、近代自然科学知识与理科学科课程的关系

从自然科学知识是理科学科课程内容形成的必要前提和自然科学知识演化成理科学科体系、课程内容的轨迹可以看出,高等学校理科学科课程发展的轨迹基本上与自然科学的演进保持同步。     

因土成俗：明清江南地区的自然地理环境与葬俗

江南地区水浅土薄的自然地理环境,给人们的营葬提出挑战。为了避免水泉之湿、虫蚁之患,人们从选择葬地、浅土葬埋、灰隔葬法以及葬后培土等方面着手应对,实践证明,综合运用这些葬法,可以在一定程度上避免自然环境带来的不利因素,达到固护棺骸的目的。反映了区域丧葬习俗与自然地理环境之间的重要关系。     

Reference priors for exponential families

Reference analysis, introduced by Bernardo (J. Roy. Statist. Soc. 41 (1979) 113) and further developed by Berger and Bernardo (On the development of reference priors (with discussion). In: J.M. Bernardo, J.O. Berger, A.P. Dawid, A.F.M. Smith (Eds.), Bayesian Statistics, Vol. 4, Clarendon Press, Oxford, pp. 35–60), has proved to be one of the most successful general methods to derive noninformative prior distributions. In practice, however, reference priors are typically difficult to obtain. In this paper we show how to find reference priors for a wide class of exponential family likelihoods.
