论航空公司航班延误的法律责任

航空运输已成为国际贸易中的重要运输方式,实践中,由于航空运输的运输延误在所难免。但对于航空公司航班延误的法律责任问题国际上却规定各异,这主要是因为各国对航班延误的法律理解不完全一致,由此带来的是对航班延误的法律责任规定不完全一致。在航空运输国际化的今天,对航班延误的法律含义进行澄清并明晰航空公司航班延误的法律责任有利于完善航空运输立法,推动航空运输国际化的有序发展。

基于排队网络的航站楼旅客规模预警方法研究

延误、取消等不正常航班事件严重影响了航空公司正常运营管理,一方面航空公司需要耗费大量资源应对延误等情况,另一方面不正常航班可能导致群体性冲突事件,带来重大的安全隐患。针对航站楼到达旅客的瞬变行为,建立开放式排队网络模型,分析航站楼到达旅客人数在瞬变行为下排队网络的性能指标,利用国内某航站楼旅客统计数据进行验证。实例验证表明:不正常航班发生后,通过排队网络模型计算并观察各节点人流,可以控制节点旅客人数,以减少因人数滞留过多而引发的群体性安全事件。     

浅析民航中断原因及影响与后备机组模型的建立

经济突飞猛进的社会对交通系统提出了严峻的考验,从地面交通到空中交通无一不面临着运量承载能力与实际运量需求的矛盾.而航班延误由于其高成本的特性往往要求其反应时间更快,运营效率更高,同时又要保证航空公司的利润,因此近年来,越来越多的目光投向了如何及时应对航班延误这一问题上.本文通过研究引起航班中断的因素和航班中断产生的蝴蝶效应,展现了民航中断因素产生的不确定性、难预测性及其影响的易扩大性,试图用增添"备用机组"的方法完善民航应对中断的反应机制,意在提高民航运营效率,降低中断影响的基础上,压低航空公司的运营成本.

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.     

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     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the     

An affordable accurate evaluation of the binding conformations predicted by molecular docking studies in bio-system

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of
