對稱因素-
( 6 ) as dean number is increased, the secondary flow firstly becomes symmetry and then the anticlockwise vortexes are enlarged, the contours of axial velocity and the stream function become symmetry, the secondary flow is intensified and the friction factor ratio increases
（ 6 ）增大dean數，二次流先趨于對稱而後逆時針方向的二次渦增大，軸向速度和流函數等值線趨向于對稱，摩擦系數比增大。 -
The concept of symmetry plan of electron spin space was put forward in this paper. the problems on eigen state of electron spin and average value of spin angular momentum projection and also on the problem of phase factor of the spin - state were analyzed and discussed
本文提出了電子自旋空間的對稱面概念，分析了電子自旋的本徵態以及電子自旋角動量分量的平均值的問題，並討論了自旋態的相因子問題。 -
The approximation order is increased by adding the factor number in the factorization of mask of multi - scaling vector with tst, and symmetry, short support of multi - scaling vector are maintained simultaneously
利用雙尺度相似變換增加其掩模分解中的因子個數以提高尺度向量的逼近階，同時保持尺度向量的緊支性和對稱性。 -
In the actuation, the feeling measure and the balance compensation, the gyroscope used the electric capacity with the high sensitivity, the low energy consumption, and combined with the high quality factor characteristic of the resonance main body, which enable its system to have the quite outstanding performance : the vibration gyroscopes were generally used to measure the rotation rate, but because of axial symmetry factor, the axial symmetry vibrating - shell gyroscope can be used to measure not only the rotation rate but also the rotation angle, moreover do not bring the accumulation error as a result of the integral
該陀螺在驅動、感測與平衡補償上採用具有高靈敏度、低能量消耗的電容，並結合諧振體高品質的特性，有相當優異的表現:振動式陀螺儀一般都是用來感測轉速，而軸對稱殼式陀螺儀由於軸對稱的因素，不僅可以用來感測轉速，而且可以感測物體的轉角，並且避免了由於積分而帶來的積累誤差。 -
( 3 ) the inhere drawback of traditional algorithms to construct bayesian networks is pointed out. so the local bayesian network metric attribute based - on bayesian dirichlet metric is also researched, and some notions on bayesian networks are presented, such as comparability, independency and symmetry on nodes etc. it is showed that the comparability is an important factor on whether two nodes is linked, and a sufficient condition for nodes with most comparability is obtained. by using this analysis on local bayesian network, the important principia are presented to create graph models
（ 3 ）由於構造貝葉斯網路圖的傳統演算法存在固有缺陷，本文通過探索貝葉斯網路圖的內在規律，主要研究基於bd度量的局部貝葉斯網路圖的度量屬性，提出網路圖中節點的相似性、獨立性及對稱性等新概念，得出相似性是兩節點連接與否非常重要的因素，對稱節點具有相同的bd度量值，獲得具有最強獨立性節點的充分條件。
