First the baths of chemical deposition co - b and co - ni - p film was investigated using perpendicular method . then the influence of rare earth was studied 采用正交化方法,通過(guò)極差分析和回歸分析確定了化學(xué)沉積co - ni - p磁性薄膜和co - b軟磁薄膜的工藝。
The genotype is a main factor in the genetic transformation via agrobacteriwn - mediated . the results of orthogonal experiments of the factors which affect mainly the transformation illuminates that the erniuxin genotype + bacterium 15 x + explant + dip - dye is the best one . the cocultivation time is 28 days . the experiment shows that : the erniuxin cotyledon regeneration frequency is very high , and that the dongnong901 hypocotyl regeneration frequency is very high 確立了農(nóng)桿菌介導(dǎo)轉(zhuǎn)化過(guò)程中基因型是影響轉(zhuǎn)化率的主要因素。通過(guò)極差分析,基因型為“二牛心” ,菌液濃度15倍的,外植體為子葉,感染方法為浸泡法是最佳的組合。農(nóng)桿菌與外植體共培養(yǎng)的時(shí)間為28h 。
Chapter two expounds chaos and fraction theory of capital market , respectively recommends the concept and characteristic of chaos and fraction theory , fractal market hypothesis , r / s analytic approach , hurst index ' s estimation and application etc . chapter three introduces methods to judge if one system have chaos and fractal phenomena , mainly use lyapunov index and fractal dimention to judge 第二章論述了資本市場(chǎng)的混沌與分形理論,分別介紹了混沌與分形的概念與特征、分形市場(chǎng)假說(shuō)、重標(biāo)極差分析法( r s分析法) 、赫斯特( hurst )指數(shù)的估計(jì)與應(yīng)用等問(wèn)題。
The paper introduced testing principle of infrared image in course of metallurgy heat engineering testing , based on several applied examples , analyzed application properties and range of infrared image technique and thermal image analysis in heat engineering analysis 針對(duì)南京某熱電廠8鍋爐燃燒調(diào)整試驗(yàn),詳細(xì)分析了正交試驗(yàn)方案設(shè)計(jì)過(guò)程中的幾個(gè)關(guān)鍵步驟,如:決定試驗(yàn)因素、選擇因素水平及選擇正交表.并且采用極差分析和方差分析方法對(duì)試驗(yàn)數(shù)據(jù)進(jìn)行了分析,提出了鍋爐在典型負(fù)荷下的優(yōu)化運(yùn)行方式
This paper has three chapters : in chapter two , the method of rescaled range analysis is used to analyze the recent return of the shanghai stock market . we introduced a new unbiased rescaled range statistic r / s * that eliminates effects of short - term dependencies . hurst exponents equal 0 . 661 and 0 . 643 respectively 本文共分為三章,第一章為引言,第二章對(duì)近年來(lái)滬市日收益率進(jìn)行r s分析,由于該法對(duì)短期記憶效應(yīng)敏感,因此介紹了無(wú)偏重標(biāo)極差分析r s ~ * , hurst指數(shù)分別為0
