Expanding the system ' s hamiltonian to a real symmetric matrix in an appropriate orthogonal basis vector and then diagonalizing it , we get the energy spectrum of the system and calculate the energy level spacing distribution function and the spectral rigidity . then we study the statistical character of the energy spectrum under the changing of magnetic field intension and find that the system ' s motion transfers from regular to chaos gradually 将系统的哈密顿量在一个适当的正交基矢下展开并对角化,得到系统的能谱,分别计算系统能谱的能级间距分布函数和谱刚度,研究了该系统量子能谱的统计特征随磁感应强度大小的改变而表现出的系统运动由规则到混沌的渐进变化。
Based on the properties of bisymmetric matrices , a class of constrained inverse eigenproblem and associated approximation problem for bisymmetric matrices were essentially decomposed into the same kind of subproblems for real symmetric matrices with smaller dimensions , and the solutions of the two problems were obtained by applying the conclusions of real symmetric matrices 摘要根据双对称矩阵的性质,将双对称矩阵的一类约束逆特征值问题及其逼近问题分解成具有较小阶数的实对称矩阵的同类子问题,然后利用实对称矩阵的结果导出双对称矩阵的这两个问题的解。
