The core thought of dendriform topology discovery algorithm is the brother-node guess algorithm, which can obtain the address space scanning by other means.

树状拓扑结构发现算法的核心思想是最小增量发现算法兄弟节点猜测算法，其优点在于采用了非地址空间扫描的手段却达到了地址空间扫描的效果。

The scheme places a few of Regional Mobility Agents to distributedly manage hosts' mobility in region. An algorithm is presented for MH to decide its RMA and regional size in terms of its mobility characteristics and some informed network parameters, which results in minimum signaling cost and packet delivery cost, but does not impose any restrictions on network's topology and RMAs' locations.

该方案在网络中放置多个区域移动代理来实现分布式的域内主机移动管理，并提出一种由主机根据自身的移动特点及获悉的网络参数动态地选择区域移动代理和区域大小的算法，该算法使得主机在域内产生的信令代价和分组传递代价达到最小，且没有对网络拓扑结构和区域移动代理的位置做任何强制性要求。

The diffusion of ethanethiol in MFI and MOR was investigated by Molecular Dynamics.

采用分子动力学方法模拟计算了乙硫醇分子在MFI和MOR两种拓扑结构沸石中的动力学性质，比较了乙硫醇不同负载量和沸石晶格原子刚性和柔性两种状态下乙硫醇分子在沸石孔道中扩散系数的大小。

In this paper, we combined with mobile agent and probability coverage model to supervise the networks topology. In order to keep the performance of network, we will let the excrescent sensor sleep and save the power of the network.

本文主要采用移动Agent技术结合使用概率覆盖模型对移动自组网络拓扑结构进行管理，在保证网络性能的同时，使冗余节点进入睡眠状态，减少网络的能量消耗。

At last, in view of the forenamed problems, this paper lodges the system planning about ERP's implementation, describes the functions of ERP software module, and carries out hardware modeling and network's topological structure.

笔者结合山西风雷机械制造有限责任公司ERP项目的实施，详细地分析了风雷公司的管理现状，提出了所存在的基础管理数据不全，业务流程衔接不畅，预算和财务管理控制不严等问题，并且针对上述问题提出了实施ERP项目的系统规划，描述了ERP系统软件各模块的功能，给出了硬件造型和网络拓扑结构。

Topological structure of the molecular phylogenetic tree, constructed by 16S rRNA gene with Neighbor-Joining method, revealed that all species of Helice from Sesarmidae and two species of Hemigrapsus from Varunidae were clustered into one branch, two species of Sesarma from Sesarmidae were clustered into another one, Grapsus albolineatus from Grapsidae and Plagusia tuberculata from Plagusiidae were formed one absolute branch respectively. The molecular analysis showed that the genus Helice indeed must be considered to be Varunidae, because it formed a monophyletic group with the genus Hemigrapsus yet not the Sesarmidae.

而采用NJ法构建的系统进化树的拓扑结构也显示，所有的厚蟹与属于弓蟹科的肉球近方蟹和绒螯近方蟹聚为一支；属于相手蟹科的2种相手蟹聚为一支；属于方蟹科的白纹方蟹和属于斜纹蟹科的瘤突斜纹蟹又各自成为一支。

The results indicate that the best model for DNA evolution of rbcL sequences in Liliales is GTR+I+G, and the topology of Bayesian tree is similar to those of Maximum parsimonious tree and Neighbor Joining tree, but giving more resolution and higher support values.

结果显示，百合目rbcL基因最适合的DNA进化模型为GTR+I+G，贝叶斯法与距离法和最大简约法构建的系统发育树拓扑结构相似，没有显著差异，但是分辨率和支持率明显比后者高。

Furthermore, the SOD can linearize circular pGEM-4Z DNA that is relaxed by topoisomerase I.

这说明酶在发生作用时要求底物DNA在拓扑结构上是受限的。

Simulation results show that the number of the network topology reconfiguration can be reduced greatly with proposed strategies. Hence the topological stability of the LEO/MEO two-tier satellite networks can be improved with acceptable cost.

仿真结果表明，与原有的策略相比，该文提出的策略能够以可接受的代价提高LEO/MEO双层卫星网络拓扑结构的稳定性。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
