The dissertation firstly put forward the running model of vc in china , the risk curve and the two methods that compute the item risk ( namely the continuous method and the discrete method ) . these are instructional meaning for us to develop vc , identify and prevent the risk 本文首次提出我國風(fēng)險(xiǎn)投資運(yùn)行模式、風(fēng)險(xiǎn)曲線和項(xiàng)目風(fēng)險(xiǎn)的兩種計(jì)算方法(連續(xù)型方法和離散型方法) ,對(duì)我國風(fēng)險(xiǎn)投資如何發(fā)展,辨識(shí)和防范投資中風(fēng)險(xiǎn)都具有一定的指導(dǎo)意義。
On the basis of the primary concepts of thermal conduction and thermal physical property of concrete material , the distributions of temperature in concrete structures are discussed in this thesis , the causes resulting in temperature - effected deformation and internal forces in the elements of the structures are analyzed . moreover , the practical approaches , such as continuous method , iteration method , finite element method , are suggested to calculate the deformations and internal forces above 本文從混凝土的熱物理特性和熱傳導(dǎo)的基本概念出發(fā),討論了混凝土結(jié)構(gòu)中的溫度分布規(guī)律,分析了高層建筑結(jié)構(gòu)中溫度變形和溫度內(nèi)力產(chǎn)生的原因,并介紹了高層建筑結(jié)構(gòu)中溫度變形和溫度內(nèi)力計(jì)算的實(shí)用方法,包括連續(xù)化法,迭代法及有限單元法。
This paper uses compare principle to show that there exists at most one of classical solution for ( 1 ) , while the existance of solution is obtained through continuous method . to get the required a priori estimates except the double normal derivatives , we adopt the method in [ 3 ] , and the double normal derivatives on dq are achieved by barrier constructions and applying skill of [ 2 ] 本文用比較原理證明了問題( 1 )至多存在一個(gè)古典解,應(yīng)用連續(xù)性方法,得到了問題( 1 )古典解的存在。在得到所需的先驗(yàn)估計(jì)時(shí),利用了[ 3 ]中的方法建立了除去邊界二階法向?qū)?shù)外的先驗(yàn)估計(jì),通過構(gòu)造閘函數(shù),用[ 2 ]中的技巧得到在邊界(
We show that near a hyperbolic set a c ~ ( 1 ) endomorphism has the lipschitz shadowing property , and a hyperbolic endomorphism has the inverse shadowing property with respect to a class of continuous methods . moreover , each of these shadowing properties is also " uniform " with respect to c ~ ( 1 ) perturbation 證明了c ~ 1自同態(tài)在其雙曲不變集附近具有l(wèi)ipschitz跟蹤性,當(dāng)c ~ 1自同態(tài)為雙曲時(shí),對(duì)一類連續(xù)method而言具有反跟蹤性,并且這兩種跟蹤性相對(duì)c ~ 1小擾動(dòng)均具有一致性。
In microcosms , there puts forward two basic methods of computing the single item , namely the discrete method and the continuous method . at the same time , there also gives the feature , the applying scope and the computing method of two methods . in macrocosms , there puts forward the meaning , the rules of appraising method system , the decision of appraising method , and the risk evaluating method in some items , and uses the ahp method to evaluate the risk with the case 風(fēng)險(xiǎn)投資項(xiàng)目風(fēng)險(xiǎn)計(jì)算方法和項(xiàng)目評(píng)估方法研究,微觀上提出計(jì)算單個(gè)項(xiàng)目風(fēng)險(xiǎn)的兩種基本方法,即:離散型方法和連續(xù)型方法,兩種方法的特點(diǎn)和適用范圍及其計(jì)算方法,宏觀上提出建立評(píng)估指標(biāo)體系的原則和意義、體系結(jié)構(gòu)的設(shè)計(jì)、評(píng)價(jià)指標(biāo)的確定和多項(xiàng)目風(fēng)險(xiǎn)評(píng)估方法,并結(jié)合案例運(yùn)用層次分析法( ahp法)對(duì)項(xiàng)目風(fēng)險(xiǎn)進(jìn)行評(píng)估; 3
