DBL access codes are generated from the left or right kronecker product of the LS codes and the extending matrix,and are called DBL left-product codes and DBL right-product codes,respectively.
DBL码由基本LS码与矩阵左、右直积生成,分别称为DBL左乘码和DBL右乘码,两类DBL码各有特点。

The concept of Kronecker product is introduced into graph theory in this paper.
将矩阵直积的概念引入图论,证明了直积图的结点数、度及特征值分别等于原图结点数之积、度之积和特征值之积,并将这些性质应用于由两个膨胀图构造一个新的膨胀图,分别从矩阵的角度和图的角度给出了构造算法。

Taking the process flow employed in Wu-Lond Gold Mine for example, this article made a deep analysis of the development and change of the process flow to treat gold-bearing lean sulphide ore and put forward direct electrowinning method in stead of CIP process to treat such kind ores.
本文以辽宁五龙金矿的生产工艺流程为例,深入分析了含金贫硫化矿选冶流程的发展与变革,提出采用直接电积提金工艺取代炭浆法工艺处理含金贫硫化矿的新设想。
6) direct product space
直积空间
补充资料：直积
设a、b是任意两个集合，在集合a中任意趣一个元素x，在集合b中任意取一个元素y，组成一个有序对（x，y），把这样的有序对作为新的元素，他们的全体组成的集合称为集合a和集合b的直积，记为a×b，即a×b={（x，y）|x∈a且y∈b}。
