So we consider five financial indexes includes stock b / p, e / p, current stock size, current stock stru and financial levge by the international tradition, then descriptive statistical test method and cross section statistical test method proved that b / p and current stock size have marked effect on the securities yield besides coefficient b. in the third chapter, the article fut forward a risk factor model, estimates yield sequences of every risk factor by weight regression, and then estimates each risk factor coefficient of different stock by time sequence regression, at last we can reckon the portfolio risk o2p and yield rp which consists n stocks
結合國際慣例,文章考慮了股票的凈值市價比( b p ) ,市盈率倒數( e p ) ,流通規模( size ) ,流通比例( stru )和財務杠桿( levge )等五個財務指標,應用描述性統計檢驗和
橫截面統計檢驗等多種方法,結果表明,除系數以外,凈值市價比( b p )和流通規模( size )對證券收益率部有重要的影響。在論文的第三章,提出了一個基於多因素的風險因子模型,並用加權回歸和時間序列回歸等方法估計出了不同證券的各風險因子系數(類似於單指數模型中的系數) ,據此,即可衡量出一個包括n只股票的組合的風險_ p ~ 2和收益率r _ p 。

Because the cross - section of the oversized rib waveguide we fabricated by wet - etching was trapeziform, we analyzed the transmission of oversized rib waveguide by combining effective refractive - index method. the influence of some factors on the optical transmission loss, such as material structure, the height of rib waveguide, and the thickness and refractive index of waveguide layer and up - layer of polymer material, was analyzed
因為濕法腐蝕工藝製作的反脊波導
橫截面是梯形狀的,因此論文中採用了一種簡單有效的方法,即有效折射率法,對梯形反脊波導的光傳輸損耗特性進行了分析,同時考慮金屬電極產生熱場對脊波導傳播特性的影響。

The section loss of steel bars and degradation of bond intensity were taken into consideration in this study in order to establish the finite element model of corroded reinforced concrete beam through simulating the bond slip behavior between steel bar and reinforced concrete based on nonlinear spring element
摘要在考慮銹蝕引起的鋼筋
橫截面損失和粘結強度下降的前提下,利用非線性彈簧單元模擬銹蝕鋼筋與混凝土之間的粘結滑移性能,建立了銹蝕鋼筋混凝土梁的有限元分析模型。
This methods is based on that when there is herding in stock market csad is going to become smaller. the results is when the markets dropping there is herding among investors, when the markets rising, there is no evidence of herding. the results prove my reasoning in section 3. why there is difference between bull and bear markets is due to investors " different attitudes towards loss and gains
通過對個股收益率分散程度指標
橫截面絕對偏離度( cross - sectionalabsolutedeviation , csad )和市場收益率之間的關系模型的回歸統計分析,本文發現:在市場行情上升的時候,市場中的羊群行為並不明顯;在市場行情下跌的時候,市場中存在明顯的羊群行為。
