Since any n×n doubly stochastic circulant matrix has a unique representation as a polynomial of degree n-1 in the shift operatorω_n,the classification problem of primes in the doubly stochastic circulant matrices can be reduced to the solution of an equation over a doubly stochastic circulant matrix.

由于任一n阶双随机循环矩阵都可以唯一地表示为移位的n-1次一元多项式，从而可把双随机循环矩阵中素元的分类问题简化为解双随机循环矩阵上的一个方程。

Pixel values in an image window are taken as a realization of a BN, and the structure and parameters of BN for each texture class are then studied. The conditional distribution probability of the pixels is used as the feature for texture classification.

把纹理图像在一个窗口内各个像素的灰度值看作贝叶斯网络的一次实现，通过训练得到各类纹理所对应贝叶斯网络的结构和参数，用纹理图像像素点在网络中的条件概率分布作为特征进行纹理分类。

The author is combination particular text and inquiry her oomph and the style of coprology from three path: first counter Zhang kangkang's style of coprology and personality have import effect and winding life story march tease and staple and generalize of humanness's stage; Secondly from novel and prose to assay her oomph of against; Lastly from eyeshot and thinking module of person and setting of person's combination and artistic conception to discuss her taste style.

本文中，笔者结合张抗抗具体的文本，从三个方面切入研究张抗抗独特的精神品质和文学风貌：首先对在张抗抗日后文学风格及个性形成产生重要影响的曲折的人生经历进行了一次综合地梳理，并对在此基础上形成的对人的认识的不同阶段进行分类、概括；第二，分别从小说和散文里，分析张抗抗抗争的精神品质；最后，从叙述视角、"人"的思维模式、人物关系的设置、意境的营造等方面，探讨张抗抗的审美特征。
