  1. So far, the main frame of the conjugation of betrand are established, on the basis of which, it is given that the primary condition the directrix line must be satisfied, the relative curvature of the conjugating surfaces, the relations between non - interventional condition and curvature axle of the directrix line, and so on. the transmission of normal circular - arc gear is a typical bertrand conjugation. in order to promote the transformation from theory to technology, the general principle of this kind of transmission is studied

    為了使研究更加貼近於工程，便於解析處理，提出準面的概念，並確立由準面到準線的研究路線，給出了各種傳動形式下準面與準線的具體特徵，證明了共軛準面上兩準線的誘導測地曲率等於零的這一不干涉條件，進而指出，當準面為平行軸和相交軸傳動的節曲面時，不干涉條件自然滿足。
  2. On the assumption of ignoring the distortion of thickness, this paper determines the rough shape by the geometric modeling method of equal area developing using mixed mesh cell of triangle and quadrangle for the first time, presents the equal area developing arithmetic of quadrangle - triangle. on the virtual geometric symmetry axis, we puts forward the method of determining the developed coordinate of the point on the base band in the development of using regular quadrangle cell, determines the developed shape of internal structure in plane utilizing point - to - point mapping theory. furthermore, we realize the approximate developing of undeveloped - irregular boundary surface using a few triangle cells

    本文結合型號研製中小曲率機翼整體壁板類零件坯料展開課題，基於板料厚向變形忽略不計的先驗假設，首創混合四邊形-三角形網格等面積展開的幾何模擬法確定壁板類零件毛坯外形，給出了混合四邊形-三角形網格等面積展開演算法；提出了虛擬分割線的概念，採用虛擬幾何對稱軸，給出了規整四邊形單元展開基帶上結點的計算方法；採用映射原理和求交演算法確定了壁板內部結構信息的展開定位。
  3. Non - affine nonlinear systems via bounded controls and kalman - yakubovitch - popov lemma of affine passive systems are stabilized. several kinds of nonlinear systems with uncertainty by using stability theory of cascaded passive systems are stabilized robustly. the relative weaker sufficient conditions of stabilizing a class of driven - driving systems by using the concept of zero - state - detectability are put forward

    運用仿射無源系統的kalman - yacubovitch - popov引理，飽和鎮定非仿射非線性系統；運用聯級無源系統的穩定原理魯棒鎮定幾類不確定系統；運用零狀態可探測概念，給出了鎮定從驅動系統相對較弱的充分條件。
  4. The usual precondition guaranteeing input - to - state stabilization by exploiting the concept of zero - state - detectability is weakened, and a class of linear systems subject to saturation by using the results above is input - to - state stabilized

    藉助零狀態可探測概念，減弱了通常文獻中所需的前提條件，在此基礎上研究了一類輸入飽和線性系統的輸入到狀態鎮定。
  5. The piecewise algebraic curve and the piecewise algebraic variety, as the set of zeros of a bivariate spline function and the set of all common zeros of multivariate splines respectively, are new and important concepts in algebraic geometry and computational geometry. it is obvious that the piecewise algebraic curve ( variety ) is a kind of generalization of the classical algebraic curve ( variety respectively )

    分片代數曲線作為二元樣條函數的零點集合，分片代數簇作為一些多元樣條函數的公共零點集合，它們是代數幾何與計算幾何中一種新的重要概念，顯然也是經典代數曲線與代數簇的推廣。
