其關鍵措施是增收節支，提高財政自身的供給能力：一方面要完善稅制，加強征管，強調集中，糾正財力分散化的趨勢，不斷提高財政收入；另一方面，要嚴格控制財政支出、優化財政支出結構、加強財政支出管理、提高財政支出效益，通過效益的提高來彌補財政收入不足，使有限的財政資金得到更充分的利用。The preference of value - added tax has become more and more, it has surely solved many special economic problems. at the same time, it has brought many troubles in principle of tax and value - added tax, it also has not fit in with the demands of tax expenditure. the preference of value - added tax should act up to this principle of tax adjusting economy, should esteem the theorem of value - added tax, and should accept the repression of budgetary control
自1993年12月13日國務院頒布《中華人民共和國增值稅暫行條例》以來，財政部和國家稅務總局以文件的形式出臺了大量稅收優惠政策，這些政策在解決一些特殊的政治、經濟和社會問題的同時，其弊端日益顯現出來，這些弊端在經濟快速增長，增值稅增勢強勁的時候不易暴露，但這不能說其危害性不大，如果不認真加以控制和規范，將會給國家稅收造成巨大損失，也可能引發諸多嚴重的經濟社會問題。Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants
文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映The researches of dynamic behavior and liquefaction potential of saturated sands have been further. however, more and more macroscopic liquefaction phenomena and experimental investigations show that different depositional environments lead to different structure of soils, while the influence of structure property of soils on liquefaction resistance is no less than that of density and consolidation stress and so on. ancient alluvial flat deposits, namely recently deposited soils, are easier liquefaction during earthquake

在當今的世界航運市場上，港口作為國際物流網路的一個重要節點，已成為綜合運輸和現代物流的樞紐，目前在我國大陸橋過境的集裝箱絕大部分是經連雲港港進出的，在東南亞國家經濟走出陰影並開始復甦、中亞地區國家經濟出現較好增長的形勢下，連雲港港的過境集裝箱箱量也將會逐年增加，現有的碼頭基礎設施與連年增加的集裝箱貨運量之間的矛盾將會日益加劇，盡快新建和擴建碼頭的基礎設施，提高連雲港港的碼頭通過能力就成了連雲港港港口建設的當務之急。Firstly, based on the analysis of the land use change and the rural settlement land change in haidian district, especially on two selected villages, it summarized the basic change trends in quantity and space in the different location, then predicted the development of residential land ( including city residential and rural settlement ) and greenbelt land of the urban fringe area in haidian in 2010 after the discussion on the relationship between the land use change and the socio - economic factors. in our opinions, in the future, in the urban fringe area of haidian will more and more lands be needed, and the function of residential land and greenbelt land will appear gradually

城市燃氣企業主要承擔城市燃氣、煤氣、液化石油氣的輸配和供應管理職能，屬于城市公用事業，這類企業由於其行業的特殊性，計劃經濟的色彩比較濃厚，企業核心競爭力不強，抵禦風險的能力比較弱，技術水平比較低，隨著國家"西氣東輸"工程的啟動和"十五"期間城市清潔能源工程的實施以及加入wto后政策面可能發生的變化，燃氣企業現有的裝備技術狀況已無法滿足社會日益增長的對天然氣資源供應的需求，無法對應國家政策變化而帶來的市場競爭，因此，燃氣企業通過技術創新和大規模的項目改造，增強企業競爭力和實力已成其為必然趨勢。Therefore, the studies in this domain were extremely needed and only small progresses were made until recently. moreover, products made by batch processes take much more share of all chemical products due to the requirements of very diversified assortments of goods in modern market. so, the studies on batch chemical processes are meaningful both in academic and economic senses
