  1. In this paper, systemic theoretic analysis of the relationship of stock structure and operating performance is progressed, based on this, theoretic study and demonstration analysis organic fall together, and the neural networks model that can reflect their relationship total and systemic is established. the input variable of the model can reflect the panorama of stock structure, also, it can embodiment other influence factor of company performance. the evaluation target system that can reflect the operating condition of listed companies completely, impersonality and truly is advanced, at the same time, the best result weights confirm method is brought forward, thereby, the fuzzy integrate evaluations method is improved

    本文對股權結構與經營績效之間的關系作了系統的理論分析，並在此基礎上，將理論研究和實證分析有機地結合起來，建立了一個能全面、系統地反映它們之間關系的神經網路模型：該模型的輸入變量在反映股權結構全貌的同時又體現了公司績效的其它影響因素；提出了可以全面、客觀、真實地反映上市公司經營狀況的評價指標體系，同時提出了最佳結果權重確定法，從而改進了模糊綜合評價方法，並利用改進的模糊綜合評價法求出公司經營績效的綜合量化值作為神經網路的期望輸出；改進了神經網路模型的演算法，使其在樣本數據相對較少的條件下也能很好地在性態上模擬被逼近函數。
  2. Firstly, in the reproducing kernel space, the spline function is discussed and its equivalent relations are gived ; we prove that the 2 - th differential operator interpolation spline function in the space can be expressed not only by the reproducing kernels but also by polygonal functions. so it is easy to prove its best approximation properties in theory and is convenient for numerical calculation in applications, too

    首先，在再生核空間中討論樣條函數，給出其等價性條件；證明了空間中的一個二階微分運算元插值樣條既可由再生核函數表示又可由折線函數表示，這不僅在理論上便於獲得此種插值樣條函數的最佳逼近性質，而且在應用上也便於數值計算。
  3. Free form surface reconstruction is a key step in reverse engineering cad modeling. on the basis of segmentation, an approach of b - spline surface reconstruction with complicated boundary constraints is addressed

    基於復雜邊界約束和內部散亂逼近的b樣條曲面重構理論和技術的研究是本文的一個重點和創新之處。
  4. This paper researches the three - layered b - spline neural network, which is commonly used in engineering and presents a constructive algorithm for selecting the number of the hidden nodes. it is proved that the proposes algorithm can be used to build a b - spline neural network with minimum hidden nodes to approximate any continuous function defined on compact set to a prescribed accuracy

    本文研究了工程上常用的三層b樣條神經網路，採用構造性的方法證明了b樣條神經網路的全局逼近能力，並且給出了構造幾乎最小隱節點的演算法，從而在理論上為b樣條神經網路的使用提供了依據。
