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。 -
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。 -
So the management has taken some technical reco nstruction and formed a linear regression model of the killing oxygen by adding aluminum process with history data. however, it is just an empirical formula, which cannot take the real time, disturbance and randomness at the spot into account. so the fitting accuracy and forecast of this model are not perfect and it is difficult to design the automatic control system about killing oxygen by adding aluminum process and achieve accurate control
為此，廠方經過了一些技術改造，通過歷史數據建立了定氧加鋁工藝的一個線性回歸模型，該模型僅僅是一個經驗公式，無法顧及具體現場中的實時性、擾動性和隨機性等諸多因素，故該模型擬合精度和預測情況是不理想的，這就給定氧加鋁自動控制系統的設計帶來一定的困難，也難以實現精確的、理想的控制。 -
For the regression estimation when the auxiliary variate is correlated with the disturbance, the bias and mean square error ( mse ) of the regression estimator are obtained, and the estimator of the mse is presented
摘要討論了輔助變量與擾動項相關條件下的回歸估計，給出了在這種條件下回歸估計量的偏差和均方誤差以及均方誤差的估計。
