面向选择性游览的景区路径推荐算法应用研究

针对目前景区路线推荐基本都从景点的热门程度以及游客可用时间的多少选择旅游路线,很少考虑到游客的个性化需求以及游览效率的现状,提出了一种基于个性化和游览效率的面向选择性游览的景区路径推荐（STRR）算法。首先通过将景区的空间结构离散化,获取游客想要游览的景点;再基于离散粒子群（PSO）算法提出利用优先级规则改进位置更新的方法,快速得到一条满足游客个性化需求的最短路径;最后以北京化工大学东校区为例利用平面仿真进行了实例验证。实验结果表明,STRR算法能够得到一条既满足游客个性化需求且游览效率最高的路径,并在计算效率方面比其他算法具有更好的优越性。

基于POI网络信息的景区最优游客接待中心选址研究——以南京钟山景区智慧旅游为例

游客接待中心是旅游景区对外形象展示的主要窗口,其选址合理与否,直接影响到其所承载的众多功能能否得到充分发挥.鉴于游客接待中心的特殊功能定位,其往往依附于景点而存在.以南京钟山风景区为研究对象,以实测网路和实际调查数据为基础,集成RS、GPS和GIS技术,建立高精度的景区POI网络基础数据信息系统,运用ArcGIS网络分析方法,从时间和空间维度揭示景区景点之间的最优路径,考察景区游客中心的最优选址.空间维度上,分析景点间的最短空间路径,并引入道路系统运输量(景点需求量)进行最短距离—景点需求量综合分析;时间维度上,以最短时间距离和中转耗时量进行综合考量.综合研究结果显示,行健亭附近为钟山风景区最优的接待中心建设处.该理论值和钟山风景区游客接待中心现实位置相比,两者空间距离280 m,可见目前钟山风景区游客接待中心接近理论最优选址点.研究为面向景区的游客接待中心选址优化提供范例,丰富了智慧旅游管理服务研究的技术方法.

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.
