On base of the data analysis, three - dimensional tide - induced residual currents, the wind - driven and thermohaline currents in the bohai sea are diagnostically computed with an orthogonal curvilinear grid system, by means of a three - dimensional ecomsed model. the winter and summer thermohaline structure and circulation characteristics in bohai sea are analysed, and the circulation variance is discussed preliminarily. the tides and tidal currents in bohai sea are well reproduced
在資料分析的基礎上，應用三維斜壓ecomsed模式對渤海的潮致余流、風生環流和密度環流進行了診斷計算，分析了渤海冬夏季的溫鹽場結構和對應環流的特徵，並對渤海上述幾個不同時期的環流變異進行了初步的分析和探討。 -

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。 -

The three main conclusions are drawn : ( i ) by choosing 19 financial indexes, this paper makes a demonstrative analysis of the annals data of the listed companies in henan province in 2004 via factor analysis method, and finds out five principle factors which have important modifying effect on the evaluation of achievements of the listed companies. they are profit factor which represents the reward structure of the listed companies, the gained profit factor which represents the profitability of the companies, the debt service factor which represents solvency of the company, the management factor which represents the managed capacity of the companies and the development factor which represents the capacity for development. each principle factor multiplying its corresponding variance contribute rate get the synthesis score of each company respectively, consequently this paper makes an comprehensive evaluation of each company
主要得出以下三個結論: （一） 、選取19個財務指標，用因子分析法對2004年河南省上市公司年報數據進行實證分析，找出對上市公司業績評價有重要影響的五個主因子，分別是代表上市公司利潤構成的利潤因子、代表公司獲利能力的獲利因子、代表公司償債能力的償債因子、代表公司經營能力的經營因子和代表公司發展能力的發展因子，綜合各個主因子得分乘以他們相應的方差貢獻率，得到各個公司的綜合得分，從而對各個公司的優劣作出一個綜合評價。 -
Via numeric sample analysis, it is found that evaluation functions are constructed by weighing principal components for pca. however, evaluation functions can be quite different when there are more than three principal components and characteristic vectors other than first one are chosen in different directions. for spca, variance contribution can be greater than 90 % by selecting just one principle component
將譜主成分分析應用於多指標評價系統中，通過數值例子分析：主成分分析是通過對各個主成分加權構造評價函數，當主成分個數不小三個時，從第二個特徵向量開始，對方向的不同選取，可導致評價函數的極大差異：而用譜主成分分析，能做到只取一個譜主成分就可使方差貢獻率大於90 。
