| 摘 要： | 提出了密集模态的拟合精度矩阵概念及相应的等精度拟合方法.在保证一定拟合精度的前提下.尽可能少的考虑频带外模态的影响,消除了无谓的计算工作量,并且把拟合结果与实际误差分析紧密的结合在一起。该法适用于大型模态试验的结果分析。

| Abstract: | The equi - precision fitting algorithm of dense modal parameter identification is presented, which defines the relationships between fitting precision and critical errors, and combines the precision of identification with the quantity of calculation directly. The examples of computation show that the results of the identification are satisfied. |
