  1. And then, some common methods of gdm, such as the ahp method, the weighted geometric mean method ( wgmm ), the borda - kendall method, the minimum variance ( mv ) method, the clustering analytic method, the cook - seiford distance measure, cb measure, the maximum and the minimum expected values, the concordance and discordance indices, etc., are used to discuss some consensus problems of gdm, including the consistency of the complex judgment matrix in ahp, the consensus methods of the aggregation of individual preferences ; the aggregation of analytic hierarchy process methods based on similarities in decision makers " preferences, a consensus measure on multiple criteria group decision making

    接著本文採用了群體決策中常用的一些方法(如: ahp法,加權幾何平均法, borda - kendall方法,最小方差法,聚類分析法, cook - seiford距離測度法, c _ b測度法,最大最小期望值法,一致性非一致性指標法等)對群體決策中的幾個一致性問題進行了研究,這些問題包括: ahp中復合判斷矩陣的一致性,個體偏好序集結的一致化方法,基於決策者偏好相似性的層次分析模型的集結中的一致性問題和多準則群體決策的一致性測度。
  2. For each block, the mean and variance values can be seen as the pixel group properties

    該方法不但考慮了像素的屬性,還考慮了像素群的屬性。
  3. All the data were analyzed by analysis of variance of spss, and it turned out some surprising and unexpected findings, which deviated from the original hypothesis : ( 1 ) chinese non - english - majored efl learners showed multiple perceptual learning modalities, which was the similar tendency with those in traditional classroom ; ( 2 ) although there was a slight decrease of the means of six instructional learning styles, there was no statistically change of the visual, tactile, kinesthetic, individual and group learning ; ( 3 ) however, there was a significant negative shift on auditory learning style of chinese non - english - majored efl learners, which was contrary to the originally hypothesis ; ( 4 ) after being analyzed as a moderator variable, gender played a significant part in the choice of instructional learning styles among chinese non - english - majored efl learners ; ( 5 ) within the group of female or male learners, it produced significant change in auditory, kinesthetic and group learning in female students while there was no significant change of all the six learning styles in male students

    而長期以來,研究者都是從理論的角度,對學習方式和計算機輔助教學進行研究,從實證角度的研究乏善可陳,基於此,本文運用定量研究的方法,著眼于調查研究計算機輔助教學對大學英語學生學習方式影響.本文以重慶大學來自8個專業的353名學生為研究對象,根據他們接受計算機輔助教學的時間長短分為三個組,進行問卷調查,對數據進行整理和分析,得出以下結論:大學英語學生傾向于多種學習方式;在六種學習方式中,有五種學習方式並沒有隨著在計算機輔助教學的環境而呈現顯著的變化;但在聽覺型學習方式上,出現了下降;從對性別的比較中,男生和女生在幾種學習方式上具有顯著的差別;而計算機輔助教學環境對男生學習方式沒有明顯的作用,卻對女生的聽覺型,體驗型和小組型學習方式有顯著影響。
  4. With the increase of variance, the difference in h - polarized or v - polarized incident wave and in the different mean cross sections is becoming gradually small until when the variance is infinity namely the rotatory axes of the group are uniformly oriented : at this time the different mean cross sections are independent of the polarized status of incident wave

    隨著方差的增大,入射波水平偏振和垂直偏振時的各平均截面的差異逐漸減小,減小到直至方差為無窮大時,即與粒子群取向的均勻分佈的情況相同,此時各平均截面與入射波的偏振狀態無關。
  5. The present methods for testing the large - scale corpus segmentation have the following faults : a. it is difficult to exactly estimating the variance of population ; b. the sampling quantity is too large to test the corpus segmentation. to solve the given problems, we put forward the testing method based on clustering, which sorts the sample of corpus into many group by clustering them

    語料庫分詞質量的評價問題是漢語語料庫的特有問題,已有的簡單隨機抽樣的方法,當語料庫規模變大時,無法精確估計分詞質量評價中語料庫樣本的總體方差,同時,為了保證檢驗的精度,傳統抽樣方法的檢驗費用太高。
  6. As goldfeld - quandt test can only be applied to one independent variable, it is generalized in the second section. it shows that, in multivariate situation, the data can be arranged according to their principle components. but there should be a premise : the disturbances of the lower data group should have equal variance and those of the higher data group have the same variance

    由於戈德菲爾德-匡特檢驗方法只適用於一個自變量,因此,本文對g - q檢驗進行了推廣,說明在多變量的情況下,可以利用主成分對樣本數據進行排序,並強調使用戈德菲爾德-匡特檢驗的前提:低樣本組各觀察值的擾動項必須具有同方差性;高樣本組各觀察值的擾動項也必須具有同方差性,否則,檢驗的結果可能是錯誤的。
  7. Part five concerns itself with data analysis and discussion, which falls into three steps : in the outset, the descriptive analysis is made to compare the scores of experimental group and control group. furthermore, one - way analysis of variance ( anova ) is made to identify whether the cognitive strategies exert a certain influence upon the achievements of post test, and then the results of employment of cognitive strategies in experimental group and control group are compared and analyzed to draw a conclusion ; finally, comparisons are conducted to analyze the differences of cognitive strategies between effective students and ineffective students

    數據分析和討論分三步進行: ( 1 )對兩組學生前、后測成績進行時比分析,並用單因素方差分析探討了認知策略是否對學生后測成績產生影響; ( 2 )通過問卷,對實驗組和對照組認知策略的使用結果進行對比和分析; ( 3 )對實驗組優秀生和后進生認知策略的使用進行對比。
  8. Analysis of variance revealed that in idea generation session, the number of ideas generated by interactive brainstorming group is larger than individual thinking group significantly

    結果表明: 1 、在創造性觀點產生階段,口頭頭腦風暴組觀點數量顯著高於個體獨立思考組。
