基于县域的山东省城镇化发展水平差异研究

遵循系统性、科学性、可比性及可获得性原则,从经济发展、人口社会发展、城市建设等3个方面选取了15个指标,构建了县域城镇化发展水平评价指标体系.运用主成分分析和聚类分析方法,对山东省140个县域的城镇化发展水平进行了综合评价和系统聚类.结果表明,山东省县域城镇化发展水平差异十分悬殊,空间分异格局特征非常明显,具体表现为:东部地区高于西部地区、沿海高于内陆、沿交通线地带城镇化发展明显高于其他地区.最后从自然条件、区位条件、经济发展水平等方面对影响县域城镇化发展的因素进行了深入探讨.     

基于超效率DEA的河南省城市效率演变特征

运用超效率DEA模型对2009—2013年河南省18个省辖市的城市效率进行测度,并对城市效率水平时空演变特征进行分析,采用空间自相关方法对2013年河南省城市效率发展水平空间差异进行了研究.结果表明:12009—2013年河南省城市效率发展水平整体呈现出"中西高-东南低"的特点,豫中、豫西地区的城市效率相比要高于豫东和豫东南地区;2河南省城市效率发展水平具有一定的正空间相关性和空间异质性,即城市效率水平相似的地区在空间上集聚分布,说明城市效率水平不仅仅取决于各地区自身的发展程度,还受相邻地区城市效率水平的影响.

通过定性分析与定量分析、聚类分析和协调性评价等方法,从技术性、社会性、交通性和通讯性四个方面界定基础设施投资指标,分析泛珠三角经济区基础设施投资与区域经济增长之间的关系,以及不同经济发展水平下城市基础设施投资的协调性差异.研究结果表明,从经济指标、总体基础设施以及基础设施不同类别的角度,对珠三角地区进行聚类会得出不同结果,总体来说,广东和福建等级较高.协调性评价的结果显示,泛珠三角地区9个省份均属于经济发展水平与基础设施建设水平协同增长型发展地区,其中广东、福建两省经济发展与基础设施建设水平之间属于协调发展,其余7个省份属于一般协调发展.     

山西省城市基础设施现代化水平综合评价

构建出山西省城市基础设施现代化评价指标体系,即道路交通、公用设施、信息通信、绿化环卫、排水排污和文化卫生.在此基础上选取了2006年的有关统计数据,采用主成分分析法和特尔菲基础上的层次分析法对山西各地市基础设施现代化水平进行综合评价,试图揭示出山西省基础设施发展水平的地区差异以及与当地经济发展水平是否相符.经过分析山西省各地级市基础设施发展水平存在很大差异,但大部分地区的基础设施发展水平与经济发展水平是相符合的.就此分析,希望能给城市建设决策者提供决策依据,城市基础设施的现代化是城市建设和发展现代化的前提和载体,我们应不断促进基础设施的建设,加快基础设施现代化的进程,以便经济更好更快的发展.

河南省乡村振兴水平区域分异及优化策略

乡村振兴是新时代中国关于农业农村发展的重大战略,如何评估各地乡村振兴水平是目前的重要问题,量化评价各地乡村振兴水平对于推进战略的实施具有重要意义.本文围绕乡村振兴战略的内涵,采用熵值法构建的县域乡村振兴综合评价指标体系包括5个一级指标和17个二级指标,借助SPSS软件平台对河南省进行了区域分异及优化策略分析,以期根据不同类型区县面临的问题,因地制宜采取针对性的措施,提升县域乡村振兴的发展质量,为推动乡村振兴战略提供参考和借鉴.研究表明：(1)河南省乡村振兴水平结构呈现出比较复杂的状态,表现为发展不均衡的结构类型,各区县的乡村振兴水平既存在差异,也存在共同特征;(2)河南省整体乡村振兴综合水平总体不高,豫中地区明显高于其他地区.河南省整体综合水平在2019年时明显高于2000年,乡村振兴工作整体推进效果明显,但各个区县乡村振兴水平差距扩大;(3)根据不同维度的特征,可将河南省122个区县划分为5个类型,针对不同类型需要采取不同的发展措施补齐发展短板.

城市化与城市土地集约利用耦合协调度评价及空间格局分析——以河南省为例

城市土地集约利用与城市化之间有着极其密切的关系,在对城市化发展与土地集约利用相互作用机理分析的基础上,以河南省为研究区域,建立城市土地集约利用和城市化评价指标体系,利用均方差法对数据进行处理,引入耦合模型,计算出河南省除济源市之外的17个省辖市土地集约利用和城市化的耦合度和耦合协调发展度,并分析了其空间格局和形成机制.结果表明:(1)河南省17个省辖市中大部分城市的土地集约利用水平和城市化的协调度不高,其中有11个城市属于较低水平或低水平协调.(2)从城市化发展类型来看,17个省辖市中有6个属于超前型,8个属于滞后型,只有3个属于同步型.(3)从协调度的空间格局分布和形成机制来看,由于各地区间的城市化发展水平和土地集约利用水平的差异,耦合协调度呈现出片状分区集聚的特征,高水平和较高水平协调地区主要集中在郑州和许昌以及与它们相邻的西部和北部地区;较低水平协调区分布在南部和东部地区以及北部的安阳、鹤壁和焦作;低水平协调区仅分布于东北部的濮阳市;不协调地区在河南省没有分布.     

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.     

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.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

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.

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that
