The partial correlation coefficients among 7 characters in wheat - rye recombinant lines were studied 本文對(duì)小麥異源(黑麥)重組系主要育種目標(biāo)性狀間相關(guān)的程度與性質(zhì)進(jìn)行了分析。
According to the analytic results in this dissertation , we can find that slope was the pivotal factor for the conversion of the burned blank into coniferous forest , and the partial correlation coefficients is - 0 . 6835 地形因子的分析說(shuō)明在火燒跡地更新種植針葉林主要是受坡度的影響,偏相關(guān)系數(shù)為- 0 . 6835 。
The effects of sowing dates on phenotype value of grain weight per plant , seed setting rate and path coefficients of seed setting rate were more effective than those on partial correlation coefficients between grain weight per plant and panicles per plaht , total spikelets per panicle and seed setting rate 播期對(duì)單株產(chǎn)量、結(jié)實(shí)率及結(jié)實(shí)率相對(duì)重要性影響較大,而對(duì)單株產(chǎn)量與單株有效穗、穗粒數(shù)及結(jié)實(shí)率的偏相關(guān)影響較小。
There is a significant positive correlation between the diurnal variation of transpiration rate and sunlight , and its partial correlation coefficient is 0 . 849 * * ; wue ( water use efficiency ) is different under different soil water content , and wue of dry plants is low 蒸騰速率日進(jìn)程與光照強(qiáng)度為顯著正相關(guān),偏相關(guān)系數(shù)為0 . 849 ~ * * ;不同土壤含水量下迷迭香的光合水分利用效率( wue )不同,受到干旱處理的植株光合水分利用效率低。
The results show that : ( 1 ) according to the results of the quantification model , the style elements of " layout " 、 " proportion of picture - word " and " number of colors used " are very related to the kansei pair of outstanding - common , but the " quantity of blank space " and " background color " are less relative . ( 2 ) the partial correlation coefficients are all above 0 . 7 between " proportion of picture - word " and seven kansei pairs 研究結(jié)果如下: ( 1 )由數(shù)量化一類(lèi)結(jié)果得知,七個(gè)型態(tài)項(xiàng)目中以版面編排、圖文比例與顏色量對(duì)突出平凡感性語(yǔ)匯之相關(guān)程度較大,而留白量與背景色彩之相關(guān)程度較小。
After synthetically analyses and researches of the existing methods for injection allocation rate , this article takes the group of water - injecting wells in waterflood oilfield as the research unit , the multiple regression method to decide the injection allocation rate is applied , by which and its regression coefficient and partial correlation coefficient , the multivariate regression models of model and model are developed 在對(duì)目前存在的配注方法的綜合分析和研究之后,提出以水驅(qū)油田注水井井組為研究單元,采用多無(wú)回歸方法來(lái)確定注水井井組配注量,并基于多元回歸方法的回歸系數(shù)和偏相關(guān)系數(shù),分別建立了多元回歸模型、 。
The second powerful item is the " layout " ( the partial correlation coefficients are above 0 . 7 , except the native - modern ) ; the least influential item is the " background color " . ( 3 ) the characteristics and performance are very similar between multiple regression model and quantification model , but the neural network model quite differs the others ( 3 )三種模式中其中復(fù)?歸分析與數(shù)量化一類(lèi)模式之特質(zhì)及調(diào)查結(jié)果兩者較為接近(預(yù)測(cè)相似度81 % ) ,而類(lèi)神經(jīng)網(wǎng)路與兩者之結(jié)果相去較遠(yuǎn)(預(yù)測(cè)相似度分別為62 %及52 % ) 。
