西瓜的故事

正夜深了,乡村的田野一片寂静。看着村子里的灯光次第熄灭,刘爷爷在瓜地巡视了一圈后回家了。想着今年风调雨顺,丰收在望,他满意地点燃了一支烟。夜更深了,两个黑影摸进了瓜地。10分钟,20分钟……他们把一辆三轮车装满了。离开瓜地才走了几步,三轮车却罢工了——陷进了一个坑。

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。     

诗与"在"--海德格尔诗学的阐释

海德格尔对荷尔德林诗歌的阐释，目的是进行诗与思的对话，归根结底还是探讨存在。诗与“在”的关系，是海氏诗学框架的核心内容，诗与“在”的关系又进一步引申为艺术与真理的关系，本从真理如何被遮蔽的问题入手，试图读解海德格尔诗学的内涵。艺术是无蔽的真理显明的一种方式，诗是危机的拯救，语言是存在的家园。海德格尔对诗与在的探讨最后又转入了对语言的探讨，无法走出语言的牢笼。只有在实践中，把艺术变成为社会变革的一个因素，才可以解放被传统理性压迫的力量，显现艺术的真理，确立艺术的价值。

普通话朗读中的停延

学习普通话的重要环节是在语流中模仿普通话的节律。停延作为节律的基础,确定了语流中的音步组合,进而关系到协同发音、连续变调等一系列语音现泉。停延的研究对于普通话的朗读教学具有重要的现实意义。该文以《普通话水平测试实施纲要》提供的60篇短文为语料,对于文中的停顿做出了定量、定性的分析：普通话的音步组合层的平均长度为5—7个音节,影响各篇短文音步组合层长度的主要因素是文体风格。该文根据60篇短文的语音资料,提出了设置句中无标点停顿的语义原则、语法原则、语用原则。根据语义原则,只能在有助于语义表达的地方停顿。根据语法原则,只能在构成语法结构的地方停顿。如果在某种情况下构成了非语法停顿,那是为了满足节律的需要。根据语用原则,人们通过对语境的分析,以停顿为手段,实现表情达意的最佳效果和节奏的匀称感。文中以大量例句,对各种语法结构中的语音停顿现泉进行比较说明,做出了令人信服的阐释。     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

Study and Development of a Simulation System for Dynamic Evaluation on Man-machine Interface Design of Advanced Main Control Rooms of Nuclear Power Plants

Since the man-machine interfaces (MMI) of a main control room provide the control platform of a nuclear power plant (NPP),the development of the design quality of MMIs plays a very important role in the operation of a NPP. With the development of digital technology, the development of the advanced main control rooms (AMCRs) has become an inexorable trend. Therefore, the positive and the negative effects of AMCRs on human factors engineering need to be evaluated. For this p~, a simulation system has been studied and developed to quantitatively evaluate a MMI design from the viewpoint of human factors. The simulation system takes advantage of computer simulation technology to simulate an operating process of an interaction between operators and a MMI design under an instruction of an operation procedure of the AMCR of a NPP. Meanwhile, the necessary data are recorded for evaluation. It integrates two editors and one simulator. In the paper, the simulation system is presented in detail. Furthermore, one sample is given to show the results of each of these three subsystems.

不同润湿性修饰石英吸附甲烷的模拟研究

润湿性是油气藏储层岩石的重要基础参数之一，其特征直接影响流体在岩石孔道内的微观分布和宏观分布特征。从微观层面认识页岩气与矿物的相互作用是深入理解页岩气赋存状态的基础。采用分子模拟研究了甲烷在不同石英模型中的吸附行为，考察了不同晶面、亲水与亲油官能团修饰模型对甲烷吸附的影响。研究结论表明，不同晶面模型中，（100）面的吸附量大于其他晶面的吸附量；甲烷在亲油修饰模型中的吸附量大于亲水修饰模型的吸附量；两种修饰模型吸附量均随着压力增加而增加，随温度的升高而减小，且温度对吸附量的影响小于孔径的影响；相同条件下，润湿性修饰模型的吸附量远大于无润湿性修饰模型的吸附量；1 nm修饰模型中甲烷只在壁面处形成吸附层，而2 nm修饰模型中形成多个吸附层。

Robust ranking of multi criteria alternatives using value functions compatible with holistic preference information

We present two recent methods, called UTAGMS and GRIP, from the viewpoint of robust ranking of multicriteria alternatives. In these methods, the preference information provided by a single or multiple Decision Makers (DMs) is composed of holistic judgements of some selected alternatives, called reference alternatives. The judgements express pairwise comparisons of some reference alternatives (in UTAGMS), and comparisons of selected pairs of reference alternatives from the viewpoint of intensity of preference (in GRIP). Ordinal regression is used to find additive value functions compatible with this preference information. The whole set of compatible value functions is then used in Linear Programming (LP) to calculate a necessary and possible weak preference relations in the set of all alternatives, and in the set of all pairs of alternatives. While the necessary relation is true for all compatible value functions, the possible relation is true for at least one compatible value function. The necessary relation is a partial preorder and the possible relation is a complete and negatively transitive relation. The necessary relations show consequences of the given preference information which are robust because “always true”. We illustrate this methodology with an example.
