Cryptic species have been found in a wide range of marine organisms ; with majority of them are benthic invertebrates. in contrast, marine holoplanktons are thought to have lower diversity and slow speciation due to their strong dispersal potential. this paper reviewed studies on cryptic species and speciation in marine holoplankton. based on findings in 38 studied taxa, it was concluded that : 1 ) cryptic species are pervasive in marine holoplankton, suggesting holoplankton speciation was more active than previously thought ; 2 ) current morphospecies diversity is untenable to reflect true species diversity in marine holoplankton ; 3 ) geographic isolation may facilitate cryptic speciation of marine holoplankton. however, contribution of allopatric speciation is still questionable ; 4 ) ecological speciation may be the prevailing speciation mode in marine holoplankton. cryptic speciation in marine holoplankton is paradoxical, because rapid speciation under strong gene flow is countertuitive. solution of this paradox will help us gain deep insights of marine speciation and biodivesity
隱種廣泛存在於各類海洋生物中，尤其是底棲無脊椎動物.然而，海洋終生浮游生物由於具有較強的擴散能力，往往被視為生物多樣性低、物種形成慢.本文就海洋終生浮游生物隱種與物種形成的研究作一綜述.基於研究的38個種類，結果表明: 1 ）海洋終生浮游生物普遍存在隱種，其物種形成要比想象得快; 2 ）由於引種的廣泛存在，形態種生物多樣性無法反映海洋終生浮游生物真正的物種多樣性; 3 ）地理隔離有助於海洋終生浮游生物隱種的形成，但異域物種形成的作用仍值得商榷; 4 ）生態物種形成很可能是海洋終生浮游生物物種形成的主流模式.海洋終生浮游生物強基因流下快速的物種形成有悖于生物進化常理，解決該悖論將有助於我們對海洋物種形成和生物多樣性的理解The basic concept of terrain information content is proposed after an overall review of existing research achievement. applying a series of analysis and data processing method, like math - analysis, mathematical statistics, comparative, error visualizing, this paper carefully investigated the terrain information content characteristic of dems of 1 : 50000 map scale of loess plateau area

將其解析解與具體的的抗震設防烈度和場地特徵周期結合起來，計算分析了成層地基中單樁的橫向地震響應，得到了以下結論： 1 ）上部結構慣性力對樁的橫向地震響應的影響不可忽略； 2 ）成層地基中的單樁的橫向地震響應主要受地震基本加速度、場地特徵周期、上部結構質量的影響，隨地震基本加速度、上部結構質量的增大而增大；場地特徵頻率越接近樁基自振頻率，樁基地震響應越大，等於自振頻率時，由於發生共振現象，樁基響應幅值最大； 3 ）樁土剛度比越大，樁土之間的相對位移的幅值越大； 4 ）樁頂固接的連接方式，可以有效地降低地震時單樁的橫向地震響應。This thesis regard internal property reorganization in the group of pangang as the research object, from chengdu seamless steel pipe limited liability company with chengdu iron and steel works inside exterior environment reorganizing in front and back commences, making use of to exceed the makel - bot with of five factors competition models and the method of factors analysis, after analyzing the reorganization of the business enterprise a profession for facing competes the situation. develop the development the business enterprise with the profession industry from the international local profession rival circumstance after analyzing the reorganization should the market position of the establishment with develop the strategy target. make use of the swot the analysis the method, to after the reorganization the development strategy of the business enterprise, from manage the angle proceeded the fixed position analyzes, for after the reorganization business enterprise development provided four kinds of developments strategy that eligibility choose : the brave development strategy, request the resources advantage, funds advantage, human resource advantage, technique advantage that new company make the most of new business enterprise in empress in reorganization, is an essential condition to increases to manage the level, quickly technique reforms, develop the high and additional worth product with new product production line, as soon as quikly change to strong and large business enterprise, realizes soon steel aircraft carrier dream ; dispersion strategy, the technology market quota with deal with produce high additional worth product, completely promote business enterprise brand image, extend high carry product of the exaltation product, is a necessary means to increases business enterprise performance, realizes business enterprise target ; defense strategy, adjusting the business enterprise organizes construction, reducing the intensive type in labor and the low additional worth product line, lower bad the property saves the deal, alleviating the business enterprise burden, attaining the casual wear go to battle, benefitting to the challenge that make frontal attack the rival ; withdraw strategy, compress the production of the high depletion and high cost product, simplify the production craft, controlling the cost of the end product in the lower level, is a valid path to increases business enterprise competition ability

植根于現代經濟的企業價值評估是資產評估中綜合性最強，技術難度最高的業務之一，也是評估業未來的發展方向，由於我國過去長期實行計劃經濟體制，企業價值概念的提出和運用時間較晚，缺少現代經營理念的積累，企業價值評估的理論與方法的研究比較滯后。本文試圖以理性分析和案例分析相結合的方法，系統研究和分析企業價值評估的基礎理論及其現實條件下，適應我國經濟發展的評估方法，以期為構建有中國特色的企業價值評估理論和方法體系做一些有益的探索。文章以企業價值評估的基本概念為起點，在對眾多關于企業性質的學說和理論觀點進行概括抽象的基礎上，指出了整體性、持續經營和盈利性是企業的重要特徵，依據企業的整體性運用系統方法闡明了企業的價值大於組成企業的單項資產價值之和，據此提出了反映企業價值評估特點的有機組合增殖假設；依據盈利性的特點，強調了企業價值評估的核心應為企業的獲利能力，而不是組建企業的成本；對企業價值、企業價值評估含義、特點的論述以及對相關概念的辨析表明了作者的個人觀點和文章的基本定位，而從評估目的入手劃分的以產權變動為目的的企業價值評估和以財務決策為目的的企業價值評估與企業價值評估的假設、評估核心共同決定了評估方法的選用。The input value of static weighing system is instant and the interference is small. nsr is high, then interference signal is ease to dispose. while dynamic weighing systems have different signal modes, yawp interference magnitude size and mode when it is in different facilities and different testing objects. in this thesis has optimum attempt in this point and find a solution which has perfect practicality
動態定量稱量技術是一項很有前景的技術，在我國發展也有很久了，但是這方面的技術還是不成熟，由於動態比靜態稱量要復雜得多，靜態稱量由於輸入值是恆定、干擾小、信噪比大，干擾信號易處理；而動態稱量系統對不同的設備、不同的測試對象產生的信號形式、噪聲干擾大小、方式均不同。Consequently, it is very necessary to make a general analysis about these influencing factors. at the first, this paper makes an analysis on the whole sample and draw a conclusion as follows : the stock - keeping ratio of management supervisors in ( msr ) chinese public companies is low, evenly distributed and vary acutely. secondly, this paper generalizes seven predictors from corporation ' s performance, ability of value development, property structure, character of human resource, and asset to explain the dependent variable msr by a multiply linearity equation
