這個結論是缺少可信度的，因為這段分析里所引用的證據並不能強有力的支持作者的主張。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 analysis of this paper has produces following results : first, although monetary transmission theories have great difference from each other, these differences lie in the adjustment scope of the assets that they investigate ; second, the methods by which money affects economy are various, so it has a strong influence, however, the change in the amount of money will not only cause the change of the total demand, it will also lead to a change in total supply by corresponding expectancy, thus in a long term we ca n ' t rely on the expansion of money to expand the production ; third, third, with the deepening of the reform, the above monetary transmission mechanisms will play a more and more important role in china ' s economy, and the influence of currency to the economy will be more and more strong, but since the correlating micro - mechanisms is mot integral, we should be highly cautious when this change takes its place
本文的分析得出了以下的結論:第一，盡管各種貨幣傳導理論有很大的不同，但是這些不同可以歸結為它們所考察的資產調整范圍的不同;第二，貨幣作用於經濟的途徑是多種多樣的，因此它的影響力是非常之大的，但是貨幣量的變動不僅會引起總需求的變動，而且會通過預期引起總供給的變動，因而在長期內不可能依靠貨幣的擴張來擴張產量;第三，隨著改革的深入，上述貨幣傳導機制在中國經濟中的作用日益加強，貨幣對經濟的影響力也越來越大，因此從長期看，貨幣政策由信貸控制轉向貨幣量控制是一個必然的選擇，但是由於相應的微觀機制尚未健全，這一轉變應高度謹慎。The experimental results indicates that the secondary mass flow increases with increasing of primary mass flow rate, but the bypass decrease because the primary mass flow rate increase more rapidly than secondary mass flow. the expansion configuration shows low thrust property due to low pressure in flow path. the secondary nozzle changes the pressure distribution in ejector combustor, and decreases bypass ratio, but obtain more completely mixing
結果表明：二次流流量隨著一次流流量的增加而增加，由於二次流流量的增加速度低於一次流，引射系數減小；在純擴張式結構實驗中，引射燃燒室壓強很低，難以實驗推力增強；二次噴管改變了引射燃燒室的壓強分佈，降低了引射系數，改善了混合狀況能；對于本文的實驗結構，存在一個最優的二次噴管出口面積，使引射火箭推力最大，同數值模擬結果相吻合。Complex interactions between classical cytokines and opioids have been found in the nervous system. the neural effects of opioids can be changed by cytokines, while the effects of cytokines can be modulated by opioids. in pha - stimulated human lymphocytes, the opioid receptor antagonist, naloxone, blunted the effect of il - 2
（ 2 ） 200u mlil 2對心肌細胞作用5min即有明顯效應，引起dl dtmax 、 dl和dl dtlnax降低，舒張末期細胞長度縮短，隨作用時間延長，其對心室肌細胞的抑制作用增強。At one point, an empty little tub chair belonging to a mysterious jedi master was to be seen in the film, and there was a serious contender to fill it
影片里一度可以見到一張空著的小巧的盆式座椅，屬於一位神秘的絕地大師，這就引入了一位強有力的議會席位競爭者。Selecting two articles on this section as its research objects, the thesis makes a deep analysis of these two news texts with “ the urban marginalized ”, a sociological term, as its connecting thread. by telling regular days ’ “ rifles ” of “ the urban marginalized ”, the narration itself comes out to be the presentation of and enquiry into the meaning of common people ’ s life, and overthrows the traditional “ mainstream narration ” in content. the narrative style of “ magnetic structure ” exhibits the living surroundings of the narration body more forcefully, although it dissects the typical linear structure conventionally used in in - depth reports
本文的研究表明，這類報道中的敘述者通過講述「城市邊緣人」日常生活中的「小事」 ，其敘述本身構成對于普通人日常生活意義的呈現與追問，在內容上顛覆了傳統的「主流敘事」 ; 「磁場式結構」的敘述方式，消解了常規深度報道慣用的線性結構，但卻更有力地展示出了敘事主體的生存氛圍，有助於推進受述者閱讀這一群體充滿變數的生活，引發真切感受;語言的修辭性指向意義的播撒，透明樸素的語言中流動著厚重的人文關懷，舒緩細膩的敘述筆調增強了敘述文本的張力。During revascularization of the graft, the increase of the blood vessel of the graft will lead to the descent of tensile strength of the graft
