The thesis based on Yellow River Diversion Project. Through the research of the existing design of the supervising system of Yellow River Diversion Project, this passage pointed out some problems hard to be dealt with as follows:(1) Owing to the dispersion of control points and remote transfers of data, it cost a lot to construct the network of the supervising system and it was hard to implement the construction.(2) The connection mode of network needed to be taken into acount. Once the configuration of network changed or the nodes increased, the supervising system needed to be reconfigured.(3) Owing to the tanglesome physical communication line, the man-made communication error happened frequently.(4) When the communication malfunction occured, it needed various engineers to check and repair the fault.(5) It cost a lot to operate and maintain the supervising system.

本文以世界银行援建项目&Yellow River Diversion Project&(引黄入晋工程，编号：0015-K81062)为背景，在对引黄入晋工程的远程监控系统进行研究分析的过程中，指出了该系统在目前采用的有线光纤和有线电缆通讯技术下难以处理的一些问题：(1)由于监控点分散且传输距离较远，有线光纤和有线电缆的网络建设成本很高，实施困难；(2)需要考虑节点之间的连接形式，一旦网络结构发生变化或节点需要扩充，监控系统便需要调整，耗费大量的人力物力；(3)由于系统庞大，通讯的物理线路较为繁乱，在建设和维护阶段容易出现人为触碰等引起的通讯故障；(4)在出现通讯故障时，需要多方人员配合进行故障检测，不仅耗费人力和物力，且不利于故障排除；(5)运行和维护成本较高，需要很多运行维护人员进行大量繁杂的工作。

The three-ring line in Beijing seems to be a small community of small nodes in major cities, small cities, so that it has been the rapid expansion forgotten, whether it is a natural social environment for the community or the community of life are floating population the surrounding high-rise buildings, bustling city noise out of tune, I lived just a few days, so I can not judge how he formed, but her presence is the first time I came to Beijing to surprise some people, the tension of Beijing has been expanding beyond the three-ring style, and even farther into the tetracyclic rings greater geographical direction, but this community did not catch up with this tide, he just quietly watching the dramatic changes around, and silence in their own small world.

这个位于北京三环线上的小社区似乎是一个大城市中的小节点，小的让它在城市的急速扩张中被人遗忘，无论是社区的自然社会环境还是社区中生活的外来流动人口都与周围的高楼大厦、喧嚣的城市繁华格格不入，我才刚刚生活了几天的时间，所以我无法判断他如何形成，但她的存在还是让我这个第一次来北京的人有些吃惊，北京城的张力已经膨胀式的越过了三环，冲向四环五环乃至更远更大的地理方向，但是这样的社区却没有赶上这样的潮头，他只是默默的关注着周围发生的剧烈变化，而沉默于自己小世界里。

This paper presents a N-R method of acquiring multi-level reasoning production rules automatically based on NN, so as to resolve the bottle neckproblem in building a knowledge - based system-knowledge acquisition. This methodadopts a characteristic NN structure model and corresponding learning algorithm, so thatN -R method can fix the number of hidden nodes dynamically and form new conceptswhich are not defined in the sample set in the course of learning.

Due to the complexity of the cell jitter, the NonSynchronous Tining Recovery methods are currently not mature With the emphasis being given to the Class A CBR traffic, this paper analyzes the performance of the queueing delay and cell jitter at the source node and intermediate nodes, and discusses the Source Timing Recovery at the destination node in ATM networks Firstly, this paper presents a description of the cell jitter of CBR traffic, and gives the definitions of two kinds of cell jitter regarding the Source Timing Recovery for CBR traffic Then, by using exact mathematical models and analysis methods, this paper analyzes the impact of the factors, such as the capacity of the queueing buffer, the randomness, the deterministic nature and the correlation in cell arrivals of the background traffic sources, on the queueing delay and cell jitter performance of the CBR traffic through Statistical Multiplexitng To obtain an insight into the power spectral distribution and look for better schemes for the depression and filtering of the cell jitter, within the analyses we succeed deriving the power spectrum of the cell jitter for CBR traffic Hence, not only the power spectral distribution of the cell jitter can in the frequency domain be qualitatively understood, but also can the rms (root-meansquare) value of the cell jitter be quantitatively obtained so as to more accurately measure the amplitude of the jitter In the end-to-end performance analysis of the queueing delay and cell jitter, we propose a kind of quasi-periodic cell stream model to characterize the jittered CBR traffic, and present an initial queueing analysis of the CBR traffic following such a model at a generic intermediate node Additionally, we briefly discuss the buildout/playout and Source Timing Recovery functions of the destination node Finally, regarding the Source Timing Recovery of CBR traffic, this paper systematically discusses several important principles of the cell jitter filtering and depression reported in the literature, introduces several implementation schemes of the Source Timing Recovery e.

由于信元抖动的复杂性，非同步定时恢复方法目前还很不成熟。本文针对A类CBR业务流在ATM网络源节点和中间节点的排队时延和信元抖动性能，以及在目的节点的源定时恢复问题作了较为全面的研究。首先，文中描述了CBR业务流的信元抖动，并具体地给出了两种与CBR业务源定时恢复有关的信元抖动的定义。然后，采用了精确的数学模型和分析方法，有针对性地分析了业务背景中信元到达的纯随机性、确定性和相关性以及排队缓存器容量等因素对CBR业务流经过统计复用后的排队时延和信元抖动性能的影响。为了了解信元抖动的功率频谱分布和寻求更好的抑制和滤除抖动的方法，在性能分析中，我们成功地完成了CBR业务流信元抖动的功率谱分析，使得不但可以从频域定性地认识信元抖动的能量分布特性，而且还可以定量地求出信元抖动的均方根值(rms：root-mean-square)，以更为准确地衡量抖动的大小。在CBR业务流的多节点端-端排队时延和信元抖动性能分析中，我们提出了一种准周期性(quasi-periodic)信元流模型来描述感染了信元抖动的CBR业务流，并基于这一模型进行了CBR业务流中间节点的初步排队分析。
