4 ) in a pre - swirl rotator - stator cavities with discrete pre - swirl nozzles and blade - cooling entry holes, the influences of pre - swirl angle and flow parameter on the flow and heat transfer characteristics were numerically investigated. the correlation for average nusselt number vs rotating reynold number or non - dimensional mass flowrate were established. the results show that : advantage of per - swirl inflow is the effect of cooling the blade - cooling entry holes ; pre - swirl inflow increases heat transfer in rotating disk of pre - swirl chamber ; as pre - swirl angle increases, local nusselt number decreases in pre - swirl chamber ; the temperature of stator of inner rotator - stator chamber and per - swirl chamber decreases as rotating reynold number increases ; when the axial mass flowrate maintains constant, heat transfer in the rotating disk of inner rotator - stator cavities does n ' t change as per - swirl mass flowrate increases, while heat transfer in the rotating disk of per - swirl chamber increases ; when the pre - swirl mass flowrate maintains constant, change of the axial mass flowrate has effect on the whole cavity
結果表明，預旋進氣的優點在於增強了葉片冷卻孔附近的對流換熱效果，局部努謝爾數隨預旋角的增大而有所減小；隨旋轉雷諾數的增加，不論是內轉靜腔室還是預旋腔室的靜盤上的溫度都不同程度的降低：當軸向中心進氣質量流量不變時，隨預旋進氣的質量流量增加，內轉靜腔室的轉盤盤面上的換熱基本沒有變化，而預旋腔室的轉盤盤面上的換熱效果增強；當預旋進氣質量流量不變時，軸向中心進氣的質量流量的改變對整個盤腔都有影響。Backed up by the soplat theory based on particle kinematics, the second chapter of this paper presents with analysis and simulation of several single observer passive measurement models, which uses such relative movement parameters as bearings changing rates and centrifugal acceleration information on the basis of bearings measurements. in the third chapter, the observability of location respectively using bearings and its changing rates information and centrifugal acceleration information is analyzed, and its observable condition is got. the fourth chapter puts forward the modified covariance extended kalman filtering ( mvekf ) against the defect of traditional extended kalman filtering ( ekf ), whose performance is simultaneously compared in the chapter with the performance of ususal tracking algorithm such as ekf, mgekf, iekf by computer simulation

針對金融市場風險管理的核心主要是對風險的測量，本文先分析了當前金融市場風險的特點，然後應用近年來在國際上受到廣泛重視並開始為大家所接受的一種全新的風險管理工具? 「在險價值」 （ valueatrisk ） var的基本思想，全面、系統地分析和測量了金融市場所存在的各種風險，並對各種var基本模型的計算、優缺點及應用作了詳細分析，最後對var模型在我國金融市場風險管理的應用提出了實質性的建議。隨著我國證券市場的發展壯大和不斷完善，及加入wto和金融市場的開放，金融產品的創新及傳統銀行表外業務的不斷拓寬，市場風險的加大必將帶來風險管理的創新並同國際接軌。所以金融市場風險管理的研究不僅具有現實意義，更具有指導意義實，這也是論文的出發點所在。Part five is also the core of the thesis which compares the programs of both chinese and japanese moral education with a focus on the analysis of the change and the essence of the japanese moral education idea from " ordinance of the educational system " to " the educational edict ", the progress and the essence of the chinese moral education idea in late qing dynasty, and contrasts the similarities and differences between them, revealing the different directions in their development

全文主要從三個角度對綜合頻道的發展進行闡述：第一部分，概括了分眾化傳播時代的特點和實質以及用圖表、相關數據結合理論分析近年來1 ，國頻道發展過程中出現的一系列的問題:即電視劇仍是各頻道播出節目的主體、一}了日1司質化傾向嚴重、頻道資源的優化組合問題啞待解決以及頻道劃分不夠科學和合理，頻道定位不明確;第二部分，從中國電視受眾的實際情況（包括受眾的年齡、性別、教育程度、家庭收入、觀眾的收視行為、文化產品的消費習慣、思維習慣和收視心理） 、中國的媒介大環境（主要是節目製作能力） 、國外的傳媒環境（側重於abc7頻道和法國電視二臺的經驗分析）三個方一面闡釋綜合頻道仍能繼續發展、大有作為的原因;第三部分，也是全文最重要的部分?中國綜合頻道的發展，錢略。If be opposite, the study of the basic theory of the basic knowledge of the party, marxism is harvested somewhat, can adopt the form that the thought reports, get on understanding of study experience, thought to raise the problem with the not clear understanding that reachs existence newly to knit a specification to leading party group ; if be opposite, the course of the party, guiding principle, policy or a central task of period have what view, oneself attitude can demonstrate in thought report, clarify oneself viewpoint ; if entered significant activity or study certain and serious article, the education that can get oneself writes leading party group to knit ; when if encounter, producing great politics event domestic and internationally, want to improve substaintial to incident knowledge through learning, banner brightly organizes the position that indicates his to the party ; if individual interest was encountered to be the same as collective interest, state interest in his daily life, produce contradictory problem, can have oneself what idea, the case that how be treated and handles organizes a report to the party ; to make leading party group knits the closest to oneself thought circumstance to understand somewhat, be about the thought state oneself, had what progress, put in what problem and the plan that will increase henceforth to wait it is clear to write. . the last share that reports in the thought, can write go up to oneself request to what leading party group knits and hope, if hope party organization strengthens the education to oneself and education, point out the effort henceforth direction is waited a moment
如對黨的基本知識、馬克思主義的基本理論的學習有所收獲，便可以通過思想匯報的形式，將學習體會、思想熟悉上新的提高及存在的熟悉不清的問題向黨組織說明；如對黨的路線、方針、政策或一個時期的中心任務有什麼看法，可以在思想匯報中表明自己的態度，闡明自己的觀點；假如參加了重要的活動或學習了某些重要文章，可以把自己受到的教育寫給黨組織；如碰到國內外發生重大政治事件時，則要通過學習提高對事件本質的熟悉，旗幟鮮明地向黨組織表明自己的立場；如在自己的日常生活中碰到了個人利益同集體利益、國家利益發生矛盾的問題，可以把自己有哪些想法，如何對待和處理的情況向黨組織匯報；為了使黨組織對自己最近的思想情況有所了解，就要把自己的思想狀況，有了哪些進步，存在什麼問題以及今後提高的打算等寫清楚… …在思想匯報的最後部分，可寫上自己對黨組織的請求和希望，如希望黨組織加強對自己的培養和教育，指出今後的努力方向等等。Especially, when the isocline of x is monotone decreasing in 0 < x < 1, the svstem has no limit cycle and is globally stable ; next, we construct a saddle bifurcation at the boundary equilibrium and a degenerated bogdanov - takens bifurcation at the interior equilibrium by choosing appropriate parameter values in the following two sections, where our work are based on the theory of central manifolds and normal torms. we prove that is a codimention 3 focus - type equilibrium. system ( 6. 1 ) will have two limit cycles at some appropriate bifurcation parameter values, and have homoclinic or double - homoclinic orbits at some other appropriate bifurcation parameter values ; at last, we study the qualitative properties of the system at infinite in the poincare sphere
因為系統在（ 0 ， 0 ）點處沒有定義，這給研究其在（ 0 ， 0 ）附近的動力學性質帶來了困難，我們應用文獻[ 17 ]中關于研究非線性方程奇點的系列理論和方法，圓滿解決了這一問題，給出了第一象限內當t +或t -時，在全參數狀態下系統的軌線趨于（ 0 ， 0 ）點的所有可能情況，其相圖也得以描繪；並且，系統不存在極限環的幾個充分條件我們也予以列出，當x的等傾線在0 x 1范圍內遞減時，系統不存在極限環，全局漸近穩定；然後，我們以中心流形定理和正規型方法為主要工具，巧妙選擇參數，分別構造了一個余維2的鞍點分岔和一個余維3退化bogdanov - takens分岔，證明了平衡點是余維3的焦點型平衡點，存在參數， m ，的值使得系統（ 6 . 1 ）有兩個極限環，還存在參數， m ，的另外值使得系統（ 6 . 1 ）有同宿軌或雙同宿軌。Lbie, based on the local boundary equation, adopts the traditional moving least squares ( mls ) approximation which depends on only the values of the nodes in the domain of the problem or along its boundary. the whole process of integration is carried on over a local domain or its local boundary centered at the node in question. the local boundary equation can be rewritten to represent the values of the unknown function at the point of interest, and the essential boundary conditions can be directly and easily enforced by using the green formula and the characters of the dirac function
它以局部邊界積分方程為基礎，採用移動最小二乘近似函數，從而只需要分佈在問題域內及其邊界上的節點的信息值，無需劃分單元；整個積分是在以節點為中心的局部域及其邊界上實現，所以不需要背景積分網格；藉助于格林公式及dirac函數的性質，將局部邊界積分方程轉化為所考慮點的未知函數的邊界積分表達式，便於直接施加本質邊界條件。Recently the properties of neutral shallow donor center d0 and negative shallow donor center d - in quantum wells with magnetic field have received a great deal of attention [ 1, 2 ]
