imprimitive graups

The principle for measuring AE signal of the fibre Extrinsic F-P interferometer instrument is analyzed.

为克服压电陶瓷传感器易受电磁干扰、不能实现长期实时检测的缺点,提出了光纤非本征F-P结构测量声发射信号的思想。

This method consists of determining both extrinsic and intrinsic elements analytically,and optimizing extrinsic elements by converse analyzing,which result in the precision of extrinsic elements and the whole equivalent circuit much improved.

这种方法包括对本征元件与非本征元件的解析求解以及逆向求解优化非本征元件 ,从而提高非本征元件值的精度 ,使得整个等效电路的精度大大提高 。

The Sufficient Conditions of Imprimitive Strongly Regular Graph;

非本原强正则图的充分条件

The primitive sign pattern matrices with the largest generalized base is characterized,and it is shown that the bound on the generalized base of imprimitive irreducible sign pattern matrices given by Shao and You is sharp.

给出了本原符号矩阵的广义基指数达到最大值时的极矩阵刻画,并证明了邵、尤给出的非本原不可约符号矩阵的广义基指数的上界是最好的。
