  4. The dissertation refers to comparatively full literatures in the field of vsc, and the development history and characteristics of vsc are summarized, and the elementary concepts, elementary definitions, elementary properties, elementary principles and design methods are particularly introduced, and the causes of the chattering phenomenon are systematically analysed, and the study status of the chattering phenomenon and the main methods to eliminate the chattering are elaborated. for the deficiencies of traditionary methods, three improved methods are developed, which are improved exponent reaching law solution, variable boundary layer solution and the solution by adding an auxiliary continuous control term. for uncertain linear systems, an adaptive fuzzy integral variable structure control stategy ( afivsc ) is put forward to eliminate the chattering around the sliding plane, which introduces fuzzy logic to soften the non - linear discontinuous sig nal in the control variable and utilizes adaptive theory to adjust output membership function according to how much the uncertainty of the system is

    比較全面地查閱了關于變結構控制理論的文獻，總結了滑模變結構控制的發展歷史和特點，詳細介紹了變結構控制的基本概念、基本定義、基本性質、基本原理以及設計方法；系統分析了變結構控制系統抖振產生的機理，並闡述了國內外目前對抖振問題的研究現狀以及消除抖振的主要方法；針對傳統抑制和消除抖振方法的不足，改進了傳統方法，得到了三種新的消除抖振的方法? ?即改進的指數趨近律法、可變邊界層法和附加連續項法；針對不確定性線性系統，在變結構控制策略中引入模糊邏輯和自適應理論來消除滑動平面上的抖振，提出了一種自適應模糊積分變結構控制方案（ afivsc ） ，利用模糊邏輯來柔化控制量中非線性不連續部分，採用自適應理論，根據系統不確定性大小在線調整模糊輸出量的隸屬函數，另外，鑒于模糊控制本質上是有靜差的，所以本文選擇了帶積分項的切換函數，由於積分項的存在使系統較正為無靜差系統。
  5. The government model should be the key to the models with proper introduction of market rules. beginning with the economic analysis on the incompleteness of the internal control system, the author probed the incompleteness of the environment and the present situation during the implementation of the internal control system ; and pointed out its intrinsic reason about the present situation of the internal control system. finally, based on the elementary theory of the system movement, the author describe the implementation safeguard mechanism of the internal control system from five aspects : strengthening correlation system ; constructing and perfecting formal system ; emphasizing the informal system ; establishing the penalty mechanism, the enlightenment of game theory in perfecting the internal control system

    本文借鑒經濟學的相關理論，對內部控制制度的基本內涵進行了擴展，認為它是指由企業利益相關者為確保資產完整、信息真實可靠，提高企業經營效率，保證既定的管理政策得以實施而採取的所有制度;在對內部控制制度傳統功能分析的基礎上，重點剖析了內部控制制度在節約企業內部交易成本，彌補企業契約的不完備性和降低代理成本方面的經濟學功能;從制度供給的角度出發指出了我國內部控制制度制定模式必須朝著「以政府為導向，引入市場規則」的模式發展;以對內部控制制度的不完全性進行經濟學分析為起點，探討了其實施環境與實施現狀的不完全性，指出令人堪憂的內部控制現狀有其內在的理由;最後以制度運行的基本理論為基礎，從內部控制相關制度的加強，正式制度的建設完善，非正式制度的重視，懲罰機制的設立，博弈論對健全內部控制制度的啟示五個角度論述了內部控制制度實施的保障機制。
  6. Part two : the elementary theory of internal control

    第二部分：內部控制的基本理論。
  7. Abstract : the paper presents a new method to study stability of power systems. it applied bifurcation approach of elementary catastrophe theory to find out control parameters bifurcation values ， which decide stability of power systems, further, stability region can be obtained. in this way, we can assess stability of power systems. the numerical simulation has shown that this method can solve effectively online stability assessment problem of power systems

    文摘:提出了一種研究電力系統穩定問題的新方法.它運用初等災變理論中分岔的概念找出決定電力系統穩定的控制參數的分岔值，從而確定了系統的穩定區域，由穩定區域即可進行系統的穩定判斷.數值模擬表明這一方法能有效地解決電力系統在線穩定判斷問題
