Galileo strongly fought against the traditional ideas of the aristotle ' s theories, and he formed the thought of identity, continuance and dialectical materialism in course of his scientific research. he had written the book dialogue concerning the two chief world systems - ptolemaic and copernican to refute the theory that the earth was static, and push the copernicus " revolution forward by protecting and advocating the cosmic principle of copernicus ; he get many scientific theories by making a thorough study of motion, so provided the materials need of which newton was ; he applied the scientific method firstly in history of science which combined mathematical inference with experience and observation organically, and entrusted modern meaning to some old - time methods, so advanced the development of scientific knowledge greatly and began the history of modern physics
伽利略強烈反對亞里士多德式的傳統思維觀念，在長期深入的運動研究中發展了同一性和連續性思想，以及把物質性質劃分為兩類的機械唯物主義思想；他著書立說駁斥「地靜說」 ，捍衛和宣揚「地動日心」的宇宙結構，推動了「哥白尼革命」 ；他深入研究運動，獲得大量科學理論，為牛頓綜合提供了豐富的材料；他在科學史上首次使用數學演繹與觀察實驗有機結合的科學方法，並賦予一些古老研究方法以現代含義，大大推進了科學認識的發展，開創了現代物理學歷史。 -

Being a widely utilized public ip platform, it is susceptible to security attacks of all nature, as outlined in the following areas : the open nature of the ip internet systems - increase of foreign attacks, for example dos / ddos attacks ; the current weakness of the existing operating system ' s internet protocol ; mainframe, and lack of an evaluation standard for back office systems, the inevitable problem of illegal internal access, the lack of guidelines for record keeping and post attack documentation processes, hi addition, still in existence, are managerial problems including the lack of securit y knowledge amongst the workforce and the inexistence of a complete set of security guidelines. to guarantee china telecom ' s 163 / 169 system ' s reliable functions, to protect the user ' s interests, at the same time, insuring quality service, it is necessary to adapt p2dr model as a solution to the current security issues. supported by the modern secure theory and made the secure implementation abundant project practices, this paper gives the general secure design for the chongqing public ip network using p2dr secure model
中國電信建設的公眾ip網對我國internet的發展起著決定性作用，重慶電信163 / 169網際網路是國家骨幹網在本地的延伸，擁有7個核心節點（採用cisco12012 、 2 * 2 . 5gdpt環） ，三十八個匯接節點，能提供寬帶，窄帶多種接入方式的公眾ip網，現擁有近20萬用戶，佔全市網際網路用戶四分之三以上，作為這樣一個擁有眾多用戶，開放的ip平臺，會受到各種各樣的安全威脅，主要表現在ip網路的開放性，來自外部的攻擊增多，如dos / ddos攻擊；所使用的操作系統運行的網路協議自身的脆弱性；主機、網路設備的配置是否缺乏評估手段；不可避免的內部非法訪問；缺乏必要的攻擊審計作為犯罪取證，出此之外，還有管理上的一些問題，如人員安全意識不強，安全制度不夠健全等多方面原因。 -
There are many plants that have the character of time - varying, large delay, large inertia in the process of production of modern power station such as the superheated steam temperature, the reheated steam temperature, the water treatment of boiler and the load regulation. some of them have the strong character of nonlinear and some of them are multivariable coupling systems it is very difficult to obtain good effect of control by conventional pid control. it is necessary to set up the mathematics models of controlled plants if applying control means of modern control theory such as self - adaptive control, optimal control ， decoupling control and predictive control. and these control systems have large calculation and bad character of real time in general. these disadvantages make them be not able to meet the need of real production process and limit the application of them in modern power station. now the generator units are developing towards large capacity and high parameters. many new kinds of generating electricity means are coming into being. the characers of production units of power station become more and more complex but the demand to quality of control becomes more and more strict. the new control means are in bad need to control them effectively
現代電站的生產過程中存在過熱汽溫、再熱汽溫、鍋爐水處理、負荷調節等許多大遲延、大滯后、特性時變的對象，它們中有些還是具有強非線性特性的對象或多變量耦合系統，採用常規的pid控制手段很難取得良好的控制效果。若應用現代控制理論中的自適應控制、最優控制、解耦控制、預測控制等控制手段，則需要建立被控對象的數學模型，而且往往控制系統的計算量大、實時性差。這些缺點使其很難滿足實際生產過程的需要從而極大地限制了其在現代電站中的應用。 -

Business valuation based on modern economy is one of the most difficult and comprehensive professional work in asset appraisal, but also stands for the trend of the appraisal. as china implemented planned economy all the long in the past years, the concept of business value was proposed later than other advanced countries. the study on the theory and method of business valuation we made is relatively backward. all these lead to that we merely use cost method in practice. with the improvement of market economy, the validity of cost method is challenged. hunting for appraisal methods suitable for china circumstance has become more and more urgent. this thesis presents its own opinion on the adjustment of the basic frame of theory of business valuation. for the first time, it puts systems theory into the study of the theory base, and believes that the enterprise as a compound entity has higher efficiency than the sum of its constituent, and then proposes new appraisal assumption. aiming at the obscure understan ding, it analyses a group of conception related to business valuation. after giving a whole analysis and study, this thesis indicates the income approach which emphasizes earning - capacity of a enterprise should become the correct choice of china, and makes a further study on the origin - features and feasibility of this method
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。 -
