关于如何提高水文资料整编精度的思考

对于水利事业而言,水文资料具有非常重要的价值。它的重要价值主要体现在两个方面：首先,汛期的预警。水文资料能够为抗洪和防汛工作提供必要的数据支持。其次,为经济发展提供水利保证。但是,水文资料整编精度容易受到以下因素的影响：首先,科学技术的发展和应用使水文资料的整编方法受到了挑战。其次,水文测验整编规范处于不断更新当中,需要水文工作者具有较强的适应能力。最后,员工素质不同以及新老员工的更替,均会对水文资料整编精度产生影响。原始的水文资料不能够进行直接的应用,必须要经过一系列的处理（计算、整理、分析、汇编）之后才具有使用价值,所以,在提高水文资料整编精度具有重要的现实意义。

水文测验中几则技术问题的探讨

1悬沙资料整编中采用近似法原因探讨 近年来,个别水文站在年度水文资料整编中,悬移质泥沙、单断沙关系点据十分散乱,并且点据不依时间顺序呈系统性偏离,而是围绕单沙-断沙关系45°线两旁左右呈不规律的分布,无法定线.由于以上原因,使两站的悬移质泥沙推求断面平均含沙量的方法不能使用单--断沙关系法,只能使用近似法整编悬移质泥沙资料.使用近似法整编悬移质泥沙资料的精度很底,其结果相当粗糙.在新颁布的水文资料整编规范中不提倡使用近似法整编悬移质泥沙资料.     

新时代水文测验的要点分析

水文测验是对各种水文要素进行系统观测及对观测资料进行整编的总称。根据水文测验资料,可以掌握各地水文要素变化规律,为水资源评价和开发利用、防洪抗旱、水源保护、生态建设提供信息。水文资料是水利工程规划设计和管理运用的基础资料之一。

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
