Merging logical topologies is a solution of network topology identification in network tomography technology.

网络拓扑合并是解决网络层析成像技术中大规模网络拓扑判定问题的重要研究方向。

The proposed network topology identification algorithm in this paper requires no support from internal nodes, it infer network internal performance and topology by using end-to-end measurement.

提出的网络拓扑推断算法不需要网络内部节点的协作，通过端到端测量推断网络内部的性能特征和拓扑结构。

Based on the degree distribution and comparison identification, the topology structure of Shenyang automobile network approaches BA(m=2) scale-free network, whose two distinct qualities are growth and preferential attachment.

3通过度分布判定和比较判定得出结论，沈阳汽车产业网络的拓扑结构最趋近于"BA(m=2)无标度网络"，这种网络拓扑模型具备的两个显著特征就是：增长性和择优性。

In the paper, the author did some research on the Graphical Model Platform of MGMS, the subsystem of MGMS. The GMP mainly has four functions as follows. The first aspect is the drawing function of micro-grid power system, including drawing power equipment, selecting power equipment and delete power equipment etc. The second aspect is the function of modifying parameters of power equipment. The third aspect is the function of topology automatic identification of the power system. The last aspect is advanced application function of GMP, including topology analysis and the real-time monitoring of the micro-grid power system which is in operation.

GMP主要要实现以下四个方面的功能：首先是设备绘图功能，包括鼠标绘制设备图元、鼠标选中设备图元、删除设备图元等基本的人机交互绘制微电网接线图功能；其次是修改已建设备的属性；再有是建立与建立的图形系统一致的电力系统网络模型，即对已绘图形的网络拓扑自动识别；最后是在此基础上的高级应用功能，包括电力系统网络拓扑的着色分析和运行数据的实时显示功能。

This is due to malicious attackers to steal, modify the network transmission of information through the Internet posing as legitimate users of illegal access to the remote host, access to stored on the host of confidential information, or take up network resources and prevent other users and so on.

这是由于怀有恶意的攻击者窃者、修改网络上传输的信息，通过网络冒充合法用户非法进入远程主机，获取存储在主机中的机密信息，或者占用网络资源，阻止其他用户使用等。

With growing Internet connectivity, it comes convenience of personal communication and development of social economy as well as growing opportunities for attackers to illicitly access computers over the network.

网络的日益普及在方便人与人之间的交流、推动社会经济发展的同时，也给黑客和恶意攻击者创造了更多的访问网络的机会，结果导致近年来的网络入侵事件的递增，给社会造成了巨大的损害。

In order to measure the passive network's conduction automatically, a network conduction instrumentation based on FPGA technology was designed and implemented according to the design principle of Virtual Instrument. System adopted FPGA technology building a digital flat-top to imitatively produce the high quality sine signal. Under the control of C8051MCU, measurement, calculation and display of the port network's conduction were automatic implementation. Furthermore, the system has the function of frequency step measurement.

摘 要：为了实现对无源端口网络的导纳进行自动测量，根据虚拟仪器设计思想，设计实现了基于FPGA的网络导纳测量仪，系统以FPGA作为数字平台模拟产生优质的正弦信号，在单片机C8051的控制和处理下，自动实现端口网络导纳值的测量、计算、显示，同时具有频率步进测量功能。

Therefore, how to get rid of network fault and improve liability of network system has became imperious question which need to resolve.

因而，如何排除网络故障，提高网络系统的可靠性，确保网络正常运行，已成为一个迫切需要解决的问题。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
