当前农村消费现状和对策探析

收入低、增长缓慢,农村社会保障不健全,农村基础设施落后,消费环境差,金融支持乏力,缺乏有效供给等是制约当前农村消费增长的主要原因,破解农村消费增长乏力的难题必须继续深化农村改革,建立农民增收长效机制,加强农村基础设施建设,改善农村消费环境,完善农村社会保障体系,建立现代农村金融制度,大力拓展农村消费信贷市场,增加有效供给,进而拉动农村消费,促进经济增长,保持农村稳定繁荣。     

网络消费：“互联网+”背景下我国农村消费新模式

在"互联网+农村"的背景下,网络消费特别是网络零售在我国农村地区迅速崛起,成为我国农村居民消费的新模式。当前,我国农村网络消费主体的个性化、消费空间的无边界、消费关系的互动性、消费行为的分享性、消费结构的合理化等新特征对我国农民、农业和农村具有重要的社会化价值。当然,由于相关配套设施及网络市场秩序等主客观条件不到位,在实践中我国农村网络消费仍存在一些问题,需要进一步的改革发展。     

流通环境对农村居民消费的影响研究——基于河南省农村的调查分析

文章以河南省部分农村地区为调查对象,通过实地调查分析农村流通环境对农村居民消费意愿及消费热情的影响。采用有序Probit概率模型计量分析表明,河南省农村居民消费水平难以有效提高的重要原因之一是农村流通体系的不完善。文章建议通过大力发展农村新型流通业态、健全农村物流系统、完善农村流通服务业等有效手段来完善农村流通环境,健全农村流通体系,以此来促进农村居民消费的增长。     

我国农村教育消费研究：现状及对策——基于城乡二元结构的视角

当前我国农村居民教育消费负担较重,农村教育消费质量不高,农村教育消费需求与供给的结构性矛盾凸显,以及农村教育消费意识尚存在一些盲点和误区,这是城乡二元结构背景下我国农村教育消费的基本现状。要破解我国农村教育消费的困境,政府应加大对农村教育事业的资金投入、为农村教育"后发赶超"提供物质基础,在此基础上破解农村教育"需求结构"与"供给结构"的矛盾,实现二者之间的匹配,最后,农村家长应更新传统观念,树立正确的教育消费观。     

扩大内需应重视增加农民收入

城乡二元消费构成我国消费需求的基本特征。当前,城市消费需求正处于转型期,而农村消费需求则有较大的增长空间。但近几年来,农民收入增速趋缓制约了农村消费需求的增长。因此,应逐步提高农民收入,以推动农村消费需求的增长。     

新农村建设中农村体育消费的新思路

中国是一个农业大国,也是农村大国,显然农村体育消费占据着基础性和根本性地位。农村体育消费是基础性、根本性消费,能活跃体育消费市场,促进相关体育产业发展。本文提出了现代农村体育消费思路的新思路,为我国农村体育的发展提供参考。     

扩大消费综述——基于消费中介的角度

中国经济要实现保增长的目标,就要扩大消费特别是居民消费。经济学家普遍认为,从长远看,要靠消费直接拉动经济增长。而农村消费被认为是我国未来消费增长的空间所在。本文综合消费中介在扩大消费方面的各种政策、措施,并简要进行了评价。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

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.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.     

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。
