As the basis for the primary transformation matrix, the rotating transformation for matrix and the primary transformation will be compounded a kind of non elementary transformation for matrix which is illustrated its practical use. 又以初等变换为基础,将矩阵的旋转变换和初等变换复合为矩阵的一种非初等(NE)变换,并举例说明了这种变换的实际应用。
The Non - elementary Property of Indefinite Integral 不定积分的非初等(NE)性
The equally effective elastic analogy was used for the local deform of the multiple impact points, thus forming the contact non linear elementary association closed equations with the dynamic equations. 文中对碰撞接触点的局部变形采用等效弹簧模拟,形成了接触的非线性本构关系,与动力方程组形成了封闭的方程组。
Non - elementary Transformation for Matrix 矩阵的一种非初等(NE)变换
This paper provides another conclusion : G is a non - ( n & 1 ) - chromatic elementary subgraph if and only if G is a n-edge critical graph. This result gives the construction of the n-edge critical graphs. 本文又得到一个结论:G是非n-1色基本子图当且仅当G是n-边临界图,从而给出了n-边临界图的构造。
