擬極小集
英文
quasi-minimal set-
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。At the same time, a series of development trend in organization structure innovation under the information environment has been put forward : flat model is the basis of organization structure optimization ; flexibility not only is beneficial to organization creation, innovation and accelerating reaction speed, but also strengthens organization ' s control centripetal force during the process of being operated continuously. it has rapid adjusting ability in time according to unexpected results of predictable change ; networking can not only decrease internal management cost and realize integration between supply chain and sale chain in worldwide, but also realize enterprise " s completely authorized managemen in order to promote substantial leap in enterprise economic benefit ; virtual model is centralizing limited resources on high additional value function and making low additional value virtual in order that the largest resource support can be obtained in the lowest cost and the whole organization is operated in the most effective way for adapting to market " s rapid change with high elasticity ; creating learning pattern in organization makes enterprise expand the width and depth of information being exchanged with the outer so as to keep enterprise in an unassailable position
提出信息化環境下組織結構創新的一系列發展趨勢：扁平化是組織結構優化的基礎；柔性化既有利於組織的創造、革新、加快反應速度，又能使組織在不斷磨合中加強控制的向心力，具有適時根據可預期的變化的意外結果迅速調整的能力；網路化不僅減少了內部管理成本、實現了企業全世界范圍內供應鏈與銷售環節的整合，而且實現了企業充分授權式的管理，極大地促進了企業經濟效益，實現質的飛躍；虛擬化是將有限的資源集中在附加值高的功能上，而將附加值低的功能虛擬化，以最小的代價獲得最大的資源支持，從而使整個組織以最有效的方式運轉，以高彈性化來適應市場的快速變化；創建學習型組織，使企業拓展了與外界進行信息交流的廣度和深度，使企業立於不敗之地。
