简介：市场过去对大规模WDN系统的偏爱现在转向了100G，2013年上半年40G网络的部署已经开始降温，100G获得了越来越多的认可，成为最主要的技术趋势。2013年第二季度，100G的销售额就已经超过了40G，Ovum预计2012～2018年间，100G都会稳居领先地位。

简介：设G是有限群，为复数域。要想找到所有不可约CG-模，一种方法是把正则CG-模CG进行直和分解，这在G的阶数比较小时不难做到，但当G的阶数比较大时计算起来比较繁琐。对于任意自然数n，本文给出了循环群Cn和二面体群D2。的正则CG-模CG的不可约模的直和分解，和这些不可约模间的同构关系。我们的方法是先构造出不可约的CG-子模，满足直和条件，从而得到正则CG-模CG的不可约模的直和分解。再运用模论知识得到这些不可约模间的同构关系。
