As an advanced materials preparation technology, spray - deposition has shown remarkable superiority in producing large - sized alloys and metal matrix composites. however, the spray deposeted preforms usually contain a certain quantity of porosity. besides, the oxide films on the surface of the particles lead to week metallurgic conjunction between the particles. in order to obtain an ideal structure and performance, the porous preforms need further densifying and plastical forming. in this paper, a new technology named wedge pressing was used to densify spray - deposeted 5a06 aluminium alloy, in which the large deformation can be obtained through the sum - up of local deformation and multi - step small deformation. this method can also solved the problems in traditional processing and greatly decreased the producing cost. what ’ s more, the reserch on the wedge pressing desification rules about the large - sized spray deposeted preforms was significant it was vital not only to the further densification of the prefoums but also to the further research on plastical deforming the research was also benefit to the industrialization an the application of the spray deposeted porous materials
坩堝移動式噴射沉積技術作為一種先進的材料制備新技術,在制備大尺寸合金及金屬基復合材料方面具有顯著的優越性。然而噴射沉積坯件特別是大型坯件通常存在一定量的孔隙,顆粒表面存在一定量的氧化膜,顆粒之間未能完全達到良好的冶金結合狀態,因此需要進行后續緻密化和塑性變形才能獲得理想的組織和性能。本文採用一種新型的楔形壓制工藝,即通過局部變形、多道次小變形累積實現大變形的緻密化加工方法,對噴射沉積多孔坯料進行后續緻密化和塑性變形,很好地解決了傳統加工工藝的難題,大大降低了生產成本。Based on funds holding stocks sample and whole stocks sample, it uses cck adjusted model to test the existence of herd behavior of funds and that of the whole stock market. then, it inserts dummy variable dt in cck adjusted model to testify whether herd behavior of funds and that of the whole stock market are the same in scale to prove whether herd behavior of funds makes stock prices fluctuate in the whole stock market

由於控制對稱量精度影響同樣很重要,所以本文還運用了一種控制方法來改善控制過程,由於在不同的環境下,控制的設備不同,系統的一些參數也要變化,這樣如果把控制點確定為固定的值,有時誤差會很大,本文是在每次識別系統一些參數來改變控制點的大小。The minimum number of state variables required is the order of the system.

其主要原因為:第一、一些影響駕駛風險或出險次數的因素是不可度量的。例如駕駛員的駕駛熟練程度,駕駛時注意力的集中程度,在緊張情況下做出反應的速度以及判斷的準確性等;第二、由於分類變量有限,可度量的因素也不可能全部包含在這些變量中;第三、由於道德風險的存在,對投保人的分組很難肯定是正確的。如有的國家的機動車保險中要求投保人告知他們的年行駛里程數,在這種情況下,保險公司很難採取什麼措施避免投保人的故意低估。Methods the data of 31 cases were analyzed based on essential items in identification of limited capacity for duties in schizophrenia in order to obtain the contribution rate of major variableds

總的看來,這些研究基本上以麥金農和肖所開創的金融抑制?金融深化理論為依據,或是側重於討論我國利率市場化改革的必要性迫切性、國際經驗、目標定位、模式選擇、次序安排、條件創造、風險控制以及貨幣政策傳導機制的改造等問題,或是側重於分析改革對各個經濟行為主體的影響,再者就是實證考察實際利率、儲蓄動員、投資質量、經濟增長各個變量之間的相關性和不同所有制經濟部門的利率敏感性。Firstly, this article summarizes consideration modes appeared in share structure reform into 3 kinds, including share adjustment, cash payment, and warrants issuance, and proves that consideration modes of share adjustment are completely equivalent to each other, and that consideration modes of share adjustment are equivalent to cash payment and cash payment is equivalent to warrants issuance when we neglect some subordinate conditions. then it is concluded that when we neglect the subordinate conditions, all kinds of consideration modes can be unified as anyone of them, and comparison between different simple or even complex consideration modes can be made. thus all kinds of considerations can be converted to a discounted ratio of stock price decline to figure consideration price of any listed companies paid in share structure reform
本文首先將股權分置改革中的對價方式歸納為股本調整類(非流通股股東向流通股股東送股、非流通股縮股、流通股擴股) 、現金對價和權證對價三大類,通過歸納兩類股東的對價水平評價指標,以及兩類股東的對價效用函數變量在一定條件下的相等,通過七個命題依次證明了股本調整類對價方式的完全等效性,以及在忽略一些次要變量的情況下股本調整與現金對價、現金對價與權證對價的等效性,由此得出在一定條件下可以將股權分置改革中的各種對價方式統一起來,以及不同類或者混合的對價方式之間可以比較對價水平的結論,並通過折算的股價降低率來表示上市公司股權分置改革的對價水平。The second part analyzes the components of the dock loading and unloading system, and the relationships between each component. furthermore, it distinguishes between junior factors and senior factors, between external variables and internal variables, and grasps main factors for further research. the third part analyzes the constitution of efficiency and variable cost of machinery, and gives formulas to calculate the efficiency, as well as the unit cost of dock machinery
