  1. By using of the richness, diversity and evenness indices, combined with twinspan, dca, dcca, multi - factors regression, correlation analysis techniques and so on, species diversity and diversification mechanism were studied. the communities were classified into eight types by twinspan. the first axis of dca indicated basically the diversification of soil water, while the second axis indicated basically the disturbance degree by people. the correlations between n, organic matter, elevation and the first axis are negative association, and the others are positive

    通過豐富度指數、物種多樣性指數和均勻度指數,結合twinspan 、 dca 、 dcca排序,多元回歸和相關分析,研究了物種多樣性及其變化機制,把植物群落分為8個群落類型;物種多樣性指數的dcca第一軸基本上反映了土壤水分的變化,第二軸基本上反映了人類對群落的干擾程度,物種多樣性指數隨土壤水分的增加而增大,隨人類的干擾程度的增加而減小。
  2. The second, the launching dynamics calculation of projectile is arranged by using the theory of uniform design, and the concept of the integrating quantity for initial disturbance and the concept of the independence factor ' s effecting degree to dependence factor is inducted too. from the model of stepwise regression, the main random factors and their effecting degrees to initial disturbance can be obtained also

    第二,用均勻設計理論安排彈丸發射動力學計算,通過引入起始擾動綜合量的概念和自變量對因變量的影響程度的概念,由逐步回歸模型分析了影響彈丸起始擾動的主要因素及其對起始擾動的影響程度,並推導了由自變量的標準差計算因變量標準差的公式。
  3. First, as using difference between " local government fiscal capacity " and " standard expenditure " as foundation to distribute the transfer payment fund, the degree of standardization is quite limited ; second, regression analysis mixes some unreasonable factors of old system, which makes this calculate way have serious shortcomings in technique ; third, this issue itself is also lack of objective and justice ; and fourth, because of the limited fund, the finance transfer payment system ca n ' t balance the fiscal capacity among regions

    但這種方法也存在明顯的不足,用「地方財力」與「標準支出」的差額作為分配轉移支付資金的依據,規范化的程度十分有限;採用回歸法摻雜了一些老體制中的不合理因素,使技術方法有嚴重的缺陷;同時,財政轉移支付的資金十分有限,起不到地區間財力均衡化的作用。
