Graphs are often as models for the multiprocessor interconnect networks, in which the vertex set corresponds to processors, and the edge set corresponds to communication links. In this case, some properties of the graphs correspond to the capability of the networks.

多处理机系统的互连网络拓扑通常以图为数学模型，这时图的顶点代表处理机，而一对处理机之间的直接通信联系则用连接这对顶点的边来表示，因此网络拓扑的性能可以通过图的性质和参数来度量。

A software HF channel simulator based on Watterson model was presented according to the characters of multipath, fading, Doppler frequency shift and Doppler frequency spread in HF channel.

In order to reduce the stealing damnify, improve efficiency and management level, we must monitor and manage the notes out of security.

市场前景：通信技术的发展以日新月异的速度进行，各种各样的节点数量越来越多，而且绝大多数都是无人值守场所，因此，出于安全的考虑，必须对此种节点进行监控和管理，以降低盗窃损失、提高效率和管理水平。

According to the practical experience of some field work after earthquakes, this paper discusses some issues about organization and management from 13 aspects, namely, the division of stage in the field work after earthquake, scale of organizing group, organization of headquarters, working deployment, seismic surveilance and analysis, macroseismic survey, social and economic effect, external propagation, connections with local government, documents and communication, guarantee of political thought and rear-...

作者根据多次现场地震工作的实践经验，从现场地震工作的阶段划分、组队规模、指挥部组成、工作总部署、震情监测分析、宏观考察、社会经济影响、对外宣传、与地方政府的联系、文书通信、政治思想保证、后勤保证和现场工作总结等13个方面对现场地震工作的组织、管理进行了讨论。文中指出了各项工作的要点及应注意的事项。

This paper mainly studies the application of distributed control system in rubber sulphuration, and design out a set of small-scale DCS that can collect the temperature in the steam pipeline in real time, calculate equivalent time of sulphuration with different temperatures and communicate with low-computer through RS-485 network to control numbers of sulphuration machines to work.

本文主要对集散控制系统在橡胶硫化领域的应用进行了研究，设计出一套小型集散控制系统。该系统能实时采集硫化蒸汽管道内的温度，计算出不同温度下等效硫化时间，并通过RS-485网络与下位机通信达到控制多台硫化机工作的目的。

There are three problems that should be deliberated when constructing a typical distributed virtual environment: 1 the representation of complex model in virtual environment, usually there are many entities and data in environment that should be recognized carefully. 2 the network communication, update and synchronal information is needed for variable entities are distributed in different computers linked by network. 3 the controlling of participant's behavior.

一是复杂模型的表达，通常这样的系统中包含复杂的较大规模的场景数据以及为数众多的实体，需要对这些实体加以组织；二是网络通信，由于环境中存在诸多可变因素，需要通知其它节点机做相应的刷新和同步，同时，分布的计算单元之间也需要交换消息或数据；三是参与者行为的控制。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
