Secondly, in our methods, the essential geometry of the image single axis geometry may be specified by six parameters and this may be estimated from one conic and one fundamental matrix (a total of 12 parameters) or may be minimally estimated from two conics (a total of 10 parameters).
本文证明了单轴旋转运动的不变量可以通过一个基本矩阵和一条二次曲线来确定,在这种情况下,由于基本矩阵的自由度为7,二次曲线的自由度为5,所需确定的参量个数仅为12,大大减少了不变量的计算量;本文同时证明单轴旋转运动的不变量可以通过最少两条二次曲线来确定,在这种情况下所需确定的参量个数仅为10,该方法是目前同类算法中参数最少的;本文提出了用多条二次曲线求解单轴旋转运动的不变量的最大似然估计算法,其所需确定的参量个数为6+2n,其中n为二次曲线的个数,该公式更深刻地反映了二次曲线与不变量的参数关系。

For example, Keyfitz made the classification of the bifurcations in one state variable, without symmetry up to codimension 7; Golubitsky and Schaeffer obtained the classification of the bifurcation problems in one state variable with Z_2 symmetry, in one parameter up to codimension 3; Golubitsky and Roberts studied the classification of degenerate Hopf bifurcation in two state variables with dihedron D_4 symmetry, in one parameter up to topological codimension 2; Melbourne obtained the classification of bifurcations in three state variables with octahedral symmetry, in one parameter, up to
需要指出的是以上研究均没有考虑分歧参数的对称性,Futer,Sitta和Stewart的工作虽然考虑了分歧参数的对称性,但仅限于分歧参数与状态变量具有相同的对称性,他们得到了状态变量与分歧参数均关于二面体群D_4对称,拓扑余维数不大于1的分歧问题的分类。高守平和李养成则讨论状态变量和分歧参数均具有对称性且对称性可以不同的分歧问题,并给出了状态(来源:A770707BC论文网www.abclunwen.com)变量关于二面体群D_4对称,分歧参数关于S~1对称,拓扑余维不超过1的分歧问题的分类。本文第一章讨论两个状态变量关于二面体群D_3对称,两个分歧参数关于O(2)对称的分歧问题,给出了该类分歧问题在非退化条件q(0)≠0下所有情形的分类与相应的识别条来源:AdadaBC论文网www.abclunwen.com

The problem with temps is that they are temporary and local.
临时变量的问题在于他们的生命周期都是临时的而且作用域是局部的,因为只在那些应用这些变量的方法的上下文中,他们才是可见的,所以临时变量更应该被封装成一个长一点方法,这是你延伸这些临时变量应用范围的唯一途径,通过用一个类似查询的方法来替换临时变量,类中的任何方法都可以访问临时变量所携带的信息,这对获得更清晰的代码有很大的帮助。
