An algebraic construction method for LDPC codes with 8-girth is proposed based on complete residue system.

最后，在分析、研究现有构造方法的基础上，基于代数中的完全剩余系，作者提出了一种代数构造方法，使得LDPC码对应因子图上的围长为8，并采用计算机对其性能进行了仿真，结果表明该码能够取得比较理想的译码性能。

If 〓 is a restricted Lie algebra and 〓-module 〓 isrestricted,then L is a restricted Lie superlagebra.

如果〓是限制李代数，并且〓模〓是限制的，则L是限制李超代数。

The semigroup algebra theory,which has a huge development under interior and exterior double Mathematical conditions form 1950"s to 1960"s,is a new branch of algebra theory.In 1990,R.Biswas gave definition of anti-fuzzy subgroup.In 1995,Shen gave definitions of anti-fuzzy subgroup and normal anti-fiizzy subgroup of group.

半群的代数理论是在数学内部和外部双重条件下，从20世纪50年代到60年代发展起来的一个崭新的代数分支。1990年，Biswas R提出了反Fuzzy子群的定义；1995年沈正维提出了一个群的反Fuzzy子群和正规反Fuzzy子群的定义。

It is proved that the set which all atoms of a BCH algebra are made up is a p semisimple BCI algebra.
