Suppose G is a finite group, then QG is a semisimple Q-algera, obviously ZG is a Z-order of QG,we denote the maximal Z-order by ?.If G is not abelian, it is not an easy thing to determine г; if G is an abelian group, then QG is isomorphic to the direct sum of a finite number of number fields, and r is the direct sum of these rings of algebraic integers of those number fields, but which elements of QG belong to r is not clear.
设G是一个有限群,那么QG是一个半单代数,ZG是QG的一个Z-序,设Γ是QG的一个极大Z-序,当G是一个非交换群时,Γ的求解是困难的问题;当G是一个交换群时,QG同构于有限多个数域的直和,Γ相应的就是各数域代数整数环的直和,但Γ具体是QG中那些元素不清楚。

Firstly,the densities of point defects and line defects in terms of the vector orderparameter fields are obtained directly from the definition of topological charges ofdefects(winding numbers of zero points of the vector order parameters),which aremore general than usually considered and will be a development of the works ofdefects done by Halperin and Mazenko.

A clone from each genotype was randomly selected as representative for sequencing. The obtained 16S rDNA gene sequences had a similarity of 87%-100% with those in the GenBank (www. ncbi. nlm. nih. gov), and more than half of them had a similarity lower than 97%, being of new species. Based on phylogenetic analysis, the bacteria in the two soils were classified into 10 groups, with 5 groups in common. The dominant bacterial groups in the two soils differed obviously. In primeval forest soil, the dominant group was Proteobacteria, which had 39 genotypes, occupying 58.0% of all the clones; while in the soil of degraded ecosystem the dominant groups were Acidobacteria and Proteobacteria, which had 19 and 15 genotypes occupying 32.5% and 30.5% of all the clones, respectively. In the soil of degraded ecosystem, Proteobacteria group decreased while Acidobacteria group increased markedly, compared with those in primeval forest soil.

To investigate the methods to effectively and simply assess the CAG repeat size of HD gene which was necessary for gene diagnosis of Huntington disease, the sequence including polymorphic CAG repeat of HD gene was amplified by PCR with TaKaRa LA Taq DNA polymerase and GC buffer. PCR products were analyzed on polyacrylamide gel to distinguish normal alleles from HD alleles. The DNA fragments of affected alleles were recovered from polyacrylamide gel as templets for secondary PCR. The secondary PCR products were cloned into T vector for sequencing analysis to determine CAG repeat size. A total of 20 normal individuals and 3 members from a HD pedigree were included in this study.
