中国生态旅游浅析

生态旅游概念的提出是实现旅游区人地关系协调和旅游业持续发展的新理念．本文就我国生态旅游发展的必要性、优势以及对生态旅游发展过程中存在的问题进行了探讨，提出了一系列有关生态旅游建设和发展的可行性建议．     

关于生态旅游的责任性理论之思考

自1983年谢贝洛斯．拉斯喀瑞提出生态旅游概念至今短短22年间，生态旅游在全球迅速得到人们的认可和接受。其内涵已得到不断的充实和完善。最新的关于生态旅游的责任性理论就是双向责任模式，本文提出了一个崭新的生态旅游三向责任模式，从三个方面即生态旅游者、生态旅游目的地及社会环境对生态旅游加以讨论。突破了以往的双向责任模式只从生态旅游者和生态旅游目的地两方面来考虑生态旅游的局限。     

体验式生态旅游的探讨

我国生态旅游分成严格意义的生态旅游与一般意义的生态旅游；深层生态旅游与浅层生态旅游；大众化生态旅游与小众型生态旅游等。这里把严格意义的生态旅游、深层生态旅游和小众型生态旅游归纳为体验式生态旅游，从体验旅游的视觉对生态旅游进行再认识，从而分析和界定体验式生态旅游。     

基于概念、原则与产品的生态旅游内涵研究

生态旅游仍是一个处于发展中的概念。从概念、原则、产品3个侧面多角度地阐述了生态旅游的丰富内涵。回顾了生态旅游产生以来影响较大的生态旅游定义，提出了生态旅游概念发展的新趋势；归纳了国内外16种生态旅游定义的主要原则，并从中提取出最重要的4条原则。对于可持续性原则，具体解释为生态可持续性、社会、文化可技术性和经济可持续性；从旅游产品的角度比较了与生态旅游容易混淆的基干旅游方式，并认为潜代性旅游、生态旅游与大众旅游的对立和排斥是暂时的、阶段性的，从发展的角度看它位有融合的趋势。

实施生态旅游环境教育的意义及对策

发展生态旅游重在教育，本文从生态旅游产生的背景和内涵出发，阐述了生态旅游环境教育的意义和对策，及旅游经营、管理、服务人员在生态旅游过程中，应具备的素质及责任心。     

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
