By sampling from the traffic flow and averaging non-overlapping blocks of size m from the original series, the variance asymptotic characteristic of the averaged series is obtained, from which this method shows that the splitting, assembling and merging process of the convergence mechanism will not change the Hurst parmeter of the traffic if the queue length of assemble buffer has a finite second-order moment.

在分析光突发交换边缘结点汇聚机制的基础上，提出了一种基于方差时间图的分析方法，利用"时间离散"和"尺度聚集"的思想，通过构造不同聚集级别m的聚集序列，分析得出业务流时间聚集序列的方差渐近性，从理论上证明了在组装器队长具有有限二阶矩的条件下，汇聚机制的分解、组装和合并过程不会改变业务流的Hurst参数。

Since the information for the generalized Jordan canonical blocks in the generalized Jordan canonical form can not be easily obtained from the characteristic polynomial and the commutative law does not hold for matrix multiplication,we compute the common form of the power of the generalized Jordan canonical form and get a concise expression for the power of the defective matrix.

考虑到不易从它的特征多项式获得构成广义若当标准型的阶数更小的广义若当块的有关信息，针对矩阵乘法不满足交换率，本文从计算广义若当标准型的幂的一般形式出发，获得实数域上亏损矩阵的幂的一个简洁表示。

By using generalized-weak commutativity mapping, the existence of common fixed point for this class of contractive type mappings is studied in complete metric space, a common fixed point theorem for contractive type mappings is obtained, which largely improve and extend the corresponding results in some references.

通过使用映象的广义弱交换条件，在完备度量空间中研究了更为广泛的一类压缩型映象的公共不动点的存在性，给出了一个新的公共不动点定理，从而在很大程度上改进和推广了现有文献中的一些结果。

Crystallized sulfuric salt of SAM was obtained by centrifuging the precipitant at 3000 rpm after adding six times the volume of absolute methanol to the decolorant liquid with a final step of freezing evaporation.

确定了分离纯化SAM的最优条件是：在pH值5.0时，含SAM浓度为3.0 g/L的上柱液，以6 L/h的流速，过装填D152树脂的离子交换柱(φ50 mm×1500 mm)后以去离子水和醋酸洗脱除杂，再用9 L到15 L浓度为50 mmol/L的硫酸以6 L/h的流速洗脱，可以分离得到纯度较高的SAM粗品。

The latter, who was still by temperament, and a school master by trade, selects a beautiful objects, puts it straight out before him and his readers, and accumulates upon it all the learned imagery of a thousand years: Shakespeare glances at it and says something of his own: it is not our intention to say that, as a describer of the external world, Milton is inferior; in set description we rather think that he was the better.

相反。Milton依然和蔼，和一个校长交换，选择一个漂亮的物体，直接放在他和他的读者面前，积累了上千年的学术心理过程。Shakespeare注视着那物体并说了一些他自己的想法。说那些话并不是我们的意图，与一名外部世界的描述者相比较，Milton是相反的。

A three-dimensional world ocean carbon cycle model with ocean biota pump is developed. In the model, the atmosphere is represented by a well-mixed box of CO 2 , where CO 2 is exchanged with CO 2 from the surface water. The carbon cycle model has been numerically integrated for 1 200 years to a quasi-equilibruium state.

建立了一个带生物泵的三维全球海洋碳循环模式，该模式在海气界面上与一个CO2 充分混合的大气箱进行CO2 交换，模式积分 1 2 0 0年达到准稳定态的海水总CO2 、碱度及溶解氧的浓度、表层新生产力、海气分压差等的分布与实测相接近。

The result will provide afundamental basis for industrial design.Firstly,based on the assumptions that the reaction generating mono-ester was controlled by the solution rate of pentaerythritol,that di-ester conversed to tri-ester rapidly and that all the reverse reactions and side reactions were omitted,the equations of reaction kinetics were obtained.

具体工作如下：(1)基于生成一酯的反应受季戊四醇溶解速率控制、二酯迅速转化为三酯和忽略所有逆反应及其它副反应的假设基础上，建立了酯交换反应的反应动力学方程，获得了不同温度下的动力学常数和速率常数的指前因子及活化能。

It is inspired by the historic traditions of cultural exchange along the ancient trade route, the Silk Road, which connected East and West.

他的灵感来源于连接东西方的古代贸易路线——丝绸之路上所发生的具有重大历史意义的文化传统交换。

After basic exchange came into existence, more complex forms developed beyond a basic barter economy, and new forms of risk manifested.

在最基本的交易出现之后，更为复杂的交易形式在物物交换经济的基础上产生，新的风险形式也应运而生。

In:In this article, the characteristics and function of switchboards and router were briefly introduced, and their respective advantages were elaborated from the view of fast retransmits、Ability to route、Connection、Redundancy connection and Network security.

1引言在当今的网络中交换机和路由器都是不可或缺的重要设备，交换技术的兴起从根本上改变了共享式局域网传送速度和容量限制；路由器在多网段互联中起到了不可替代的作用。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
