  1. At first, this paper analyzes the factors of water - sand influencing water level of yellow river and the feasibility just using the factors of water - sand to study water level, and collects the corresponding data ; secondly, because there are strong nonlinear relation in the corresponding data, by meticulous theory analysis, this paper integrates basic nonlinear analysis method, theory of random analysis, method of least squares and so on. it puts forward a method which can get the high accuracy simulation of the data, perfects the multi - factor analysis of variable ( over three factors ) of the statistic ; thirdly, it applies the method to the approximation of corresponding water level process which belong to the capacity of sand of middle - high and middle - low, and get the high - accuracy simulation about the typical nonlinear relation ; at last, this paper definitudes the main influence mode that the capacity of sand. it mainly unite with other factors to work on the water level in the yellow river lower reaches ; mor eover, this paper analyzes the difficult point and the direction of improvement to realize the accuracy forecasting of the flood level of erodible - bed channel

    首先，系統分析了影響黃河水位的水沙因素，及僅用水沙因素有效研究水位的可行性，並按變量對應思想採集它們的相應數據；其次，由於相應水位過程數據中含極強的非線性關系，本論文經細致的理論分析，將基本的非線性分析方法、統計建模方法、隨機分析理論、最小均方誤差原則等等數學理論及方法有機揉合，提出了能有效實現這類數據高精度擬合的分層篩選法，並改進了統計學中多因子（三個以上）方差分析法；再次，將這一方法用於黃河中高及中低含沙類洪水相應水位過程的擬合，實現了這一典型非線性關系的高精度擬合，各年汛期上下游相應洪水位過程的擬合誤差都較小；最後，明確黃河下游含沙量對水位的主要影響方式，即含沙量主要是與其它因素聯合對水位作用；另外分析了要實現變動河床洪水位過程準確預報的困難所在及改進方向。
  2. Stepwise selection of main influencing factors from observational data with one dependent variable and multiple factors

    單變量多因素觀察性資料主要影響因素的逐步篩選
  3. The research on the influencing factors is conducted in multivariate regression model, while the dea technical efficiency estimates are referred as dependent variable

    本文進一步以技術效率為因變量，對影響銀行效率的銀行微觀特徵進行多元回歸分析。
  4. Because the different stiffness match of front and rear suspension is very influencing to the ride comfort, optimal model of ride comfort is developed, regarding the rms of driver ’ s acceleration as the objection, regarding the stiffness of front and back suspension as optimal variable, regarding quiet flexibility 、 dynamic flexibility 、 frequency and dynamic load as nonlinear constraints. by matlab program and using sqp, the optimal match of front and back suspension ’ s stiffness is achieved, this optimal model consider not only request of quiet 、 dynamic flexibility 、 frequency and damp, but also security of run and peace of road, it is closer to the fact than other models which only consider partial restriction

    由於前後懸架垂直剛度的不同匹配對汽車行駛平順性影響較大，論文建立以駕駛員垂直加速度的均方根值作為汽車行駛平順性優化目標值、以前後懸架垂直剛度作為優化變量的優化設計模型，並輔以靜撓度、動撓度、頻率、動載荷等非線性約束，使用序列二次規劃法，利用matlab編制優化程序，求得前後懸架垂直剛度的最優匹配值;此優化模型不僅包含動靜撓度及頻率和阻尼的限制，還考慮到汽車的行駛安全性和道路友好性，比文獻報道的只考慮部分約束的優化模型更切合實際情況。
  5. Consequently, it is very necessary to make a general analysis about these influencing factors. at the first, this paper makes an analysis on the whole sample and draw a conclusion as follows : the stock - keeping ratio of management supervisors in ( msr ) chinese public companies is low, evenly distributed and vary acutely. secondly, this paper generalizes seven predictors from corporation ' s performance, ability of value development, property structure, character of human resource, and asset to explain the dependent variable msr by a multiply linearity equation

    其次，本文從業績、價值成長能力、股權結構、管理者人力資本特徵以及公司規模五個方面出發，抽象出對管理層持股具有影響作用的七個解釋變量，構造了以管理層持股比例為被解釋變量的多元線性回歸方程，利用spss11 . 0軟體，採用全部納入法和逐步回歸分析法進行回歸擬合，並採用標準參數檢驗（ t檢驗和f檢驗）來確定其相關顯著性。
