According to the data of the analyses,revealed the population of Cryptomeria fortunei exhibited clump distribution pattern,single-dominant community type,sporadic type population structure and is able to natural regenerate...

柳杉种群呈典型的集群分布，并随个体的增大，由集群分布向随机分布发展的趋势，为间歇型的种群结构。通过对天目山柳杉的起源及其更新类型的探讨表明：天目山柳杉林属天然林与人工林共存状态，并可通过幼苗库进行天然更新，但具有机会性和波动性，需林窗和林内倒木等条件。图3表2参25

Agglomeration can also supply firms with opportunity conditions, appropriability conditions, degree of cumulativeness and knowledge base which are the most important factors to innovate

企业在市场环境、制度环境的影响下，其合作行为、创新能力和竞争优势之间形成了正反馈：合作行为促进了企业的反复学习，企业利用聚集形成的创新条件，加快了集群的创新活动，形成了集群的创新优势，创新活动反过来又促进企业之间的合作

WPA Cracker customers get access to a 400-node computing cluster that employs a custom dictionary, designed specifically for guessing WPA passwords.

WPA破解服务的用户能够使用一个400个节点的计算机集群。这个计算机集群使用一个专门为猜WPA口令设计的一个客户化的字典。

So G = PQ,Q for which q -order cyclic group, P - G, P and G is the Frobenius for the Frobenius group of nuclear.

则G = PQ，其中Q为q阶循环群， P - G，且G是以P为Frobenius核的Frobenius群。

We present linear codes over finite fields with Mannheim weight and prove that those codes can correct one error taken from a cyclic subgroup of the multiplicative group of finite fields, which provide an algebraic approach in coding modulation.

最后讨论了有限域上的Mannheim线性纠错码，证明了当错误取值于有限域乘群的一个循环子群时，面向多维信号的线性分组码可以纠单个错并为码调制提供了一种代数渐进方法。

In this paper, new classes of linear block codes over finite fields of the algebraicinteger ring of quadratic number fields Qd~(1/2 modulo irreducible elements with norm p or p~2 are presented. These codes can correct one error which takes from the cyclic subgroup of the multiplicative group of the finite fields. The results presented in this paper extend the corresponding results of previous papers.

在处理适用于二维信号的线性分组码时，我们考虑类数为1的有理数域二次扩域Qd~(1/2的代数整数环，利用范数为p或p~2的不可约元构造有限域，给出剩余类域的一组完全陪集代表元系，从而构造出一类有限域上的线性分组码，当错误取值于有限域乘法群的一个循环子群时，所得到的适用于二维信号的线性分组码可以纠单个错，推广了文[14-16]的结果。

If each minmal subgroup or cyclic subgroup of order 4 of H is π-quasinormally embedded in G, then G∈F.

如果H的极小子群或4阶循环子群均在G中π-拟正规嵌入，则G∈F。

If every minimal p-subgroup of G is containedin Z, every cyclic subgroup of order 4 of G is conditional c-normal in G, then G isp-nilpotent.Theorem 2.3.9 Let p be a fixed prime.

定理2.3.9对某个固定的素数p，设G的每个极小p-子群包含于Z，4阶循环子群在G中条件c-正规，则G是p-幂零的。

Generally,we often use the notions of transposition and cyclic transformation etc for definit-ing deferminant.

定义行列式时，一般要用到对换、置换等概念，置换群还是有限群的一个重要例子，本文对这些概念反轮换作一些探讨，得到了一些结果。

With the application of concept and method of programme stratigraphy and event stratigraphy,starting with the research for the cycle sediment,where the cyclothem of sequence of the outcropping stratum of mesoproteroxoic and neoproteroxoic era grade may be classificated into four different grade there occur from old to new one in Fangjinshan monutain group,one in Xiajiang group the same as one first stratum,and two in Sinian system involving Ti...

应用层序地层学及事件地层学的概念和方法，从沉积旋回的研究入手，首次在该区出露的中、新元古代地层中划分出 4个不同级别的旋回层，即梵净山群 1个(相当于 1个一级层序)、下江群 1个(相当于 1个一级层序)、震旦系 2个(即铁丝坳组—大塘坡组和南沱组—灯影组，相当于 2个二级层序)。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。
