刻划

Abstract： Bipartite graphs with P-regular endomorphism monoids are characterized.P-regularity of the endomorphism monoid of lexicographic product of graphs is discussed.

：刻划了具有P-正则自同态幺半群二分图，讨论了字典序积图自同态幺半群P-正则性.

Their properties were characterized by using integral transformation and matrix theory.Two biorthogonality formulae for the multiple vector-valued multivariate wavelet packets were obtained.

运用积分变换与矩阵理论，刻划它们性质，得到两个双正交公式。

The method of two point probe focus is proposed to resolve the proble m of the jog of focus, and unitization processing is used to eliminate the chang e of laser power.

提出了采用两点探焦法解决刻划时焦点跳动问题，采用归一化处理消除光强波动对调焦精度。
