對179例高血壓腦出血患者,按腦出血的部位、血腫量、有無腦室積血和中線結構移位,分別進行比較並發消化道出血的發生率和病死率.結果表明: 179例中並發消化道出血44例( 24 . 6 % ) ,死亡37例( 20 . 7 % ) ;消化道出血發生率以腦基底節區出血並腦室積血為最高( 38 . 9 % ) ,其次依序為蛛網膜下腔、腦干、腦葉、小腦和局限於腦基底節區出血;並發消化道出血的病死率為50 % ,無消化道出血的病死率為11 . 1 % .腦出血並發消化道出血主要與出血溢入腦室、中線結構移位、血腫量大等因素有關,且病死率高Introduced by prestressed pier in the gate of spillway in xiao xia hydroelectric power station, the text reasonably established 3 - d finite elements mechanic model by the advanced finite elements popular in the world which can expediently impose tension of anchor funicular at its place. it also considered possible diversified combination of loading, and indicated that the effect of its prestressed action is fruitful compared with its conventional counterpart by study of mechanic calculation in comparison. as a result, it vastly improved burdening state of pier. by analysis of 3 - d finite element method, it also gained the stress result indifferent boundary conditions such as breast wall joint support and fixed support, and the displacement result in diversified loading combination. those results gained the instructive and reference value in design of prestressed pier
本文結合黃河小峽水電站泄洪閘預應力閘墩這一工程實踐,採用國際上已成熟的有限元方法,合理地建立了預應力閘墩的三維有限元模型,該模型可方便地按預應力錨索的點位施加錨索預張拉力,考慮了可能發生的多種荷載工況組合,並與無預應力閘墩結構進行了對比分析研究,指出其預應力效果是明顯的,可以大大改善閘墩結構的受力狀態,通過三維有限元分析,還得到了胸墻簡支、固端不同情況下的應力成果和各荷載下的位移成果,這些成果的取得對預應力閘墩的設計具有一定的指導和參考價值。Following, making development study from the three directions : the first one is how to reduce calculation when to use markowitz model. this text has improved the efficient frontier of markowitz model utilizing free risk assets, and reduced calculation about revenue rates " co - variance matrix utilizing single or multiple factors, and so on. the second one is to add thinking factors about, such as transaction fee, fund limitation, lowest transaction unit ' s limitation, risk measures and exchange rate risk of international portfolio securities, so as to make markowitz model closer to our country ' s practice
接著,分三今方向對markowitz模型進行了拓展研究:第一個方向是運用markowitz模型時如何減少計算量,本文利用無風險資產來改進markowitz模型的有效邊界,利用單因子或多因子模型來減少收益率協方差的計算量等等;第二個方向是增加考慮因素,諸如交易費用、資金限制、最小交易單位限制,風險測度和國際組合證券的匯率風險,使markowitz模型更貼近我國的實際;第三個方向是對markowitz模型進行動態拓展研究,提出了將證券收益率看成是隨機序列時的投資決策模型,深入研究了m ? v有效邊界隨資產品種數增加而發生的漂移,並用解析方法和幾何圖形描述了漂移的軌跡和方向。A bearing surface transmits the interaction between an arch dam and its foundation, the strength of which directly affects the constraint of the bedrock to the dam, and thus affects the stress and deformation of the dam. the influence is studied in this paper with nonlinear finite element method, as an example, for a high arch dam in design. the results show that the influence on stress is only limited within the local area near the bearing surface, larger on the maximum principal tensile stress than on the principal compression stress, and the decrease of the strength does not cause unlimited increase of the maximum stress. the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam, especially the relative downstream displacement. at the lower strength of the bearing surface, the relative downstream displacement at the bottom of the dam increases with the decrease of the strength
建基面是傳遞拱壩和基巖相互作用的紐帶,它的強度直接影響基巖對壩體的約束,從而影響壩體的應力和變形.採用非線性有限單元法,以設計中的某高拱壩為例,分析建基面強度對壩體應力和變形的影響.結果表明建基面強度對壩體應力的影響僅限於建基面附近的局部范圍,對最大主拉應力的影響要大於對最大主壓應力的影響,建基面強度的降低不會無限地增大壩體的應力數值;建基面強度對壩頂位移的影響較小,但對壩底位移(尤其是順河向相對位移)的影響較大,當建基面強度較低時,壩底順河向相對位移隨建基面強度的降低而增大The floor of the high - rise frame structures is very suppleness when the frame structures subjected to the vertical seismic actions, it is impossible to confirm that each member has the same displacement in the same floor, so it is impossible that the summation of axes stiffness of each vertical member represent the global vertical stiffness of the frame structure
高層建築框架結構在豎向地震作用下,樓板在豎向剛度是很小的,一般不予考慮,認為相對無限柔性,而梁的剛度也是有限的,不可能保證各豎向構件在同一樓層豎向位移相同,因此不能簡單地用各豎向構件軸向剛度之和來代表結構的總豎向剛度。In a small warehouse and asked wooden box into the designated location, you are not careful there will be a box or can not move to block the route. so skillfully use limited space and access
在一個狹小的倉庫中,要求把木箱放到指定的位置,稍不小心就會出現箱子無法移動或者通道被堵住的情況,所以需要巧妙的利用有限的空間和通道Test result suggests, in the serviceability limit states, displacement is littleer, the plane stiffness infinite assumption may be established
實驗結果表明,在正常使用極限狀態時,位移較小,同一樓層平面內剛度無限大的假定可以成立。Otherwise the fundamentally of choice of base type and groundsill disposal scheme is expatiated ; the effect of the rigidity enhanced layer for increasing of horizontal stiffness and restriction of displacement is analyzed. in the article, the optimization design of beam and plate is produced, and it is analyzed that the application of non - felt prestressed concrete beam and plate decrease the layer height and the cost
文章從基礎方案的比選和優化,闡述了基礎選型和地基處理方案選擇優化的重要性;分析了在高層建築中設置剛性加強層對增加水平剛度、限制側向位移的作用,同時介紹了梁板設計的優化,分析了採用無粘結予應力梁板對于減小層高節約造價的重要意義。分享友人
