「最滑稽的是，很多人都無法拿出正式的資格證明來向他們的家人朋友和用人單位證明自己的外語水平，他們到底是能夠非常流利的運用一門外語還是只能用外語進行簡單的對話無人可知。 」The development of science and technology journal is limited obviously by its circumstance such as region, contribution, reader, etc. under the influence of these conditions, the confined mind and the unenterprise attitude is produced by editors. thus, the weak link of developing science and technology journal is showed conspicuously in blazing new trails of content, expanding circulation, and founding famous brand. for expanding the developing space of science and technology journal, some effective measures should be adopted. first, the content and quality of journal should be highly valued. the constantly bring forth new ideas in the content should be promoted by publishing original theses, supporting new subject, introducing new direction, creating characteristic column, etc. by means of these methods, the aim of spreading original achievement, starting new fields of scientific research can be achieved. so academic standard and effect of the journal can be improved. second, the operate mechanism of journal as a processing workshop should be changed. the varied methods should be adopted for selling, circulating and information feedback of journal. third, the reputation of the journal should be safeguarded by correcting ideology of publish. the resources of the journal should be rationally used and developed. it can promote the science and technology journal growing continued
科技期刊的發展受到地域、稿源、讀者等環境因素的制約.受其影響，編輯易產生封閉、不思進取的心態，使科技期刊在內容創新、擴大流通、創立品牌等方面突現出薄弱環節.為拓展科技期刊的發展空間，首先應抓內容和質量，通過刊發創新論文、扶持創新學科、引進創新方向、創辦特色欄目促進科技期刊內容創新，以傳播創新成果，開辟創新領域，提高期刊的學術水平，擴大影響力;其次，應改變純粹的生產單位、加工車間的運作機制，採用多種局道、多種方法加強科技期刊出版后的營銷、流通及信息反饋等工作，走出重生產、輕開發、輕流通的誤區，擴大影響面;第三，應端正出版理念，維護刊物的聲譽，合理利用、充分拓展科技期刊的品牌資源，促進科技期刊的可持續發展With the development of productivity and the improvement of science and technology, the constant elevation of consume standard, the more and more fierce competition between enterprises and the huge change of economy politics and society environments largely enhanced the incertitude of market, hence enterprises transformed their managements mode from vertical integration to horizontal integration in succession, supply chain management ( scm ) is typical representation of horizontal integration management idea. scm has been introduced to our country last years, but concerned departments of government and some enterprises seriously paid attention to it. as the important part of scm, logistics is the essential key for success or failure of scm
隨著科學技術的進步和生產力的發展，顧客消費水平不斷提高，企業之間的競爭日益激烈，加上經濟、政治和社會環境的巨大變化，使整個市場的不確定性大大增加，於是企業紛紛將「縱向一體化」管理模式轉變為「橫向一體化」 ，供應鏈管理就是「橫向一體化」管理思想的一個典型代表。供應鏈管理引入我國是最近幾年的事，但是受到了政府有關單位和企業的高度重視。而物流作為供應鏈管理的重要組成部分，對供應鏈管理的成敗起到至關重要的作用。As the customers require commodities of individuation rather than of popularity, the management should be upgraded accordingly. and the organizational structure of the enterprise changes from the traditional pattern of hierarchies directed by purely cost and efficiency to the flat pattern directed by many target include pursue innovation, then to the pattern of network and so on, as the enterprise supplies products or services aiming at the individual rather than at the mass generally ; meanwhile, it is required that the corporate supply chain should be changed into the relationship of alliance rather than that of purely market trading
隨著顧客需要從大眾化向個性化轉變時，要求企業管理的質量水平相應的提升，企業提供產品或服務的流程形式從大量生產向單件生產轉變，企業的組織結構隨之從單純成本、效率目標導向的傳統層級型演變到追求創新等多目標的扁平型再發展到網路化組織形式等，同時要求供應鏈從純粹的市場交易轉為相對穩定的聯盟式的關系，並由此引起企業管理形式的變化。Firstly in the paper the research of hydraulic characters and the optimize of structure have being carried out on the four bigger design schemes of permanent internal dissipation discharge tunnel reconstructed from the right bank ' s diversion tunnel of gongboxia power station with a method of theoretical analysis combined with test comparisons. on this basis, two form swirling flow internal dissipation schemes, vertical and horizontal axis are recommended to the construction unit of the station as the schemes to be selected next
