For some shortcomings of unknown quantity numbers in finite element method, QR-method establishes a transformed relationship between a unit node displacement vector and the entire framework of spline node displacement vector,making the structure of the total stiffness matrix, damping matrix, mass matrix directly superimposed in no need of finite element method in the first expansion after the superposition process. So the method greatly simplifies the calculation process and improves computing speed.
针对有限单元法中未知量数目很多的缺点,QR法建立起单元结点位移向量与整个框架样条结点位移向量的转化关系,使得结构总刚度矩阵、阻尼矩阵、质量矩阵可以直接叠加,不需要有限单元法中先扩张后叠加的手续,大大简化了计算过程,提高计算速度。

Boley and Golub used Gauss quadrature formula to solve the inverse problem, but I used other different methods and thoughts. I obtained a new decomposition form of orthogonal matrix consisted by the unit eigenvectors of Jacobi matrix and found the direct relations between the first row and the orther rows of this orthogonal matrix.
Boley和Golub的算法是用高斯求积公式,而本人另辟蹊径,推出了关于Jacobi矩阵单位特征向量组成的正交阵的一种分解形式,并找到此正交阵第一行和其它行的直接联系,由此避免了通过求特征多项式计算尾主子阵的特征值,得到了新的稳定解法。
