As an example, the implementation of the laplace equation with the gridless method has been presented at first and the resulting large scale matrix equations are solved by gmres algorithm. the numerical simulations of the flows over a cylinder are tested successfully with clouds of different scales, which shows the " cloud " effects on the computational accuracy
本文先以代表定常不可壓位勢繞流的laplace方程為例,研究了laplace方程的無網格離散形式,並運用gmres高效演算法對其快速求解,數值模擬了典型的圓柱繞流;並通過不同點雲尺度的數值模擬,顯示出點雲尺度對計算精度的影響。By means of linear matrix inequalities, a sufficient con dition is given for uncertain discrete singular system to be generalized quadratically stable and strictly passive, based on which, a sufficient condition is given for the existence of a state feedback controller, such that the resulting closed - loop system is both generalized quadratically stable and strictly passive for all the admissible uncertainties, all conclusions carry with them corresponding examples to prove the effectiveness, and the corresponding controllers are also presented
利用線性矩陣不等式,給出不確定離散廣義系統廣義二次穩定且嚴格無源的充分條件,並在此基礎上給出存在狀態反饋控制器,使得閉環系統廣義二次穩定且嚴格無源的充分條件。每一節均給出數值算例來說明結論的有效性,同時給出相應的控制器構造。As composite material are widely used in navigation and physical education equipments for high comparing intensity and module, even it has the approxi - mate zero expanding coefficient, as the same time, configuration of composite has been aroused attention by scientific researchers, the goal of them is to find an integrated structure with high efficiency and intelligent and many function all along. grid structure is the right structure with the high efficiency, the researchers overseas have been studying the structure for many years, which manifests it has many excellent nature ; existing research indicate it has higher stiffness and intensity. the form can be detected in health easily for its open shape
復合材料具有高的比強度和比模量,同時又具有近於零的熱膨脹系數和良好的尺寸穩定性等優良性能,已經廣泛應用於航天航空事業和體育器材生產工業,與此同時,尋求一種高效的、低成本的、並將智能化和功能化集於一體的結構形式,一直是航空航天追求的目標,具有點陣結構的復合材料格柵結構正是這種高效的結構形式,表現出多項優良性能;國外對其進行了大規模的理論分析和一些數值模擬研究,已有的研究表明該結構具有良好的可設計與自動化生產性能而無材料之間匹配問題,開放式的結構形式為結構的健康檢測提供了便利,具有廣闊的應用前景。The paper is composed of five chapters the first chapter first introduces the concept, characteristics and the course of development of the stock index futures, then deduces the pricing formula of stock index futures and further analyses the functions of stock index futures and the impact of its transaction on the fluctuation of the spot transactions. the second chapter demonstrates the need and feasibility of the introduction of the stock index futures in china. through the empirical analysis of the market risk of china ' s stock market, we can see that the risk difference between individual stocks, so a portfolio investment wo n ' t help much in risk aversion
本論文共分為五章,第一章在介紹股票指數期貨的概念、特點以及產生與發展的過程的基礎上,對股票指數期貨的定價公式進行了推導,從而引出股票指數期貨的套期保值、指數套利、資產配置、組合保險等作用,進而分析股票指數期貨交易對股票現貨市場波動性的影響;第二章主要是對中國推出股票指數期貨的必要性和可行性進行論證,通過對中國股票市場風險測度的實證分析,得出了中國股票價格波動齊漲齊落,個股之間的風險差異小的特點,因此,投資者進行投資組合的避險效果就很有限,無論是個人投資者還是機構投資者,都必須面臨中國股票市場巨大風險的事實。分享友人
