让"龙头"昂起来——苏州市农业龙头企业的产业化之路

农业龙头企业是指以加工和销售为龙头,联结基地和农户,具有较强的辐射带动作用,能够促进农业增效和农民增收的规模型企业。实践证明,推进农业产业化经营,关键是培育和发展壮大农业龙头企业,核心是辐射、带动农业、农民。农业龙头企业是推进农业产业化的有效载体,是促进农业结构调整,发展效益农业的客观要求,也是提高农业市场竞争力的重要措施。近年来,苏州市积极培育农业龙头企业,这些昂起来的“龙头”带动着千千万万的农户走向市场,推进社会主义新农村建设,农业产业化经营取得了明显成效。据统计,到2005年底,苏州市年销售收入超500万元或利税超50万元的规模型农业龙头企业共有企业330家,比上年同期增加42家,实现销售收入510亿元,利税总额25.5亿元,出口创汇3.3亿美元,同比分别增长15.6、17.0%和3.1%,联结农户125.6万户,带动各类种、养基地面积433.7万亩。两个省级重点农产品批发市场实现交易金额和交易量分别比上年增长29.2%和4.3%。

重构淮北农业发展新的支撑体系

改革开放以来,淮北市农业取得了明显的成效,粮食产量、人均收入、产业结构调整出现了前所未有的成绩.但是,面对我国全面加入WTO和市场农业竞争加剧的现实,不能盲目乐观、更不能沾沾自喜.目前淮北市农业仍面临千家万户的小生产与千变万化的大市场之间、农民生产规模小与实现农业产业化之间、农业的社会效益高与农业自身效益低之间、农产品过剩与农业结构调整缓慢之间和社会对农产品多样化、优质化、方便化、绿色化的高需求与农产品加工低之间的矛盾.呈现出农村工业化、农业市场化、国际化、农村城镇化趋势和农民组织化趋势.面临如何实现中长期粮食供应平稳、如何实现劳动力充分就业、如何实现农业和农村经济可持续发展的问题.     

财政支持农业产业化项目管理探究

农业产业化项目对于促进农业结构调整和优化,增加农民收入起着四两拨千金的作用,为解决＂三农＂问题做出了贡献。农业产业化项目的开展通常需要通过政府财政进行支持和引导,有效的项目管理则是这种财政支持方式成功的关键。本文通过介绍福建省农业产业化项目的财政投入现状和取得的成效,分析其存在的问题,最后从立项评审、过程管理、制度建设和统筹协调等方面对财政支持农业产业化项目管理提出建议。     

关于厦门市农业社会化服务体系建设的对策研究

一、厦门农业社会化服务体系现状与问题 农业社会化服务是伴随着农业生产由分散的、孤立的、自给自足的小生产方式转变为分工细密、协作广泛的商品化社会生产而产生的,是农业产业化发展和现代化建设的客观要求.改革开放以来,我市农业社会化服务体系建设取得一定成效.     

我省农业产业化的发展

农业产业化问题,是关系到农村深化改革和农村经济发展的一个重大课题。为深入探讨这个问题,推进我省农业产业化的发展,本文拟就其含义、组织形式、产生发展的客观必然性以及怎样推进农业产业化问题,谈些粗浅认识。     

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
