查询词典 arithmetic progression

this paper makes the gas remote monitor network as background to do some research on the qos guarantee of the network.qos is a synthesis guide line which can be used to estimate the degree to satisfy with some server,which is a technology to solve the problem of delay and congestion in network.it must integrate multi-qos mechanism to get good qos guarantee in the practical application.three qos models in the ip net application and homologized affective factors are demonstrated.meanwhile,the field of qos protection strategy arrangement in shaanxi coal mine gas network has been picked up as the example.for this situation,the comparison to the different qos models is doing strictly.by combining the tcp congestion control arithmetic with ip congestion control arithmetic,the paper also emphatically describes the corresponded arithmetic model for that.stimulatingly,it is promoted the qos characteristic over-area effectively,which it is based on the original single congestion control.

摘 要：以陕西煤矿瓦斯监测远程联网为背景，研究其联网网络的qos保障策略实现。由于现有的各种qos实现机制无法单独为陕西煤矿瓦斯监测联网网络的qos提供保障，因此在实际应用中必须结合多种机制才能得到较好的qos保障效果。比较了传统ip网络的qos结构体系，通过分析intserv和diffserv两种模型的基本原理、工作方式，并指出其各自的优缺点和网络应用环境，设计了将rsvp协议与diffserv模型相结合来满足瓦斯监测数据传输实时性的要求；针对陕西煤矿瓦斯联网的特性，提出了将tcp拥塞控制算法与ip层拥塞控制算法相结合的算法模型，并且该模型的应用可以在原有单一拥塞控制的基础上有效地提升跨地区网络的qos特性。关键词：服务质量；综合服务模型；区分服务模型；拥塞控制

母线微机保护装置已发展的比较成熟，装置通用的选择故障母线的方法是利用总差动和分差动相配合；文中介绍了利用分差动选择故障母线时的两种算法，分析了利用母联电流方向比较元件选择故障母线的方法，并从瞬时值方面和向量值方面提供了两种算法。

The paper puts forward immunity arithmetic used in distribution network on the basis of analyzing common uncertainty arithmetic and immunity arithmetic theory. It gets an optimizing project for distribution network, in which the equilibrium of load is regarded as target function.

3在分析常见的非确定性算法和进化免疫算法原理的基础上，提出了在配电网络重构中采用免疫算法，并求解以负荷均衡为目标函数的配电网络重构的最优方案，实例表明该方法具有较快的收敛速度和较强的全局搜索能力；同时本文还为实时配电网络重构定义了启动条件，避免在配电网络正常运行时频繁启动网络重构。

The first is what are the fewest points of motion necessary to animal progression, the second why sanguineous animals have four points and not more, but bloodless animals more than four, and generally why some animals are footless, others bipeds, others quadrupeds, others polypods, and why all have an even number of feet, if they have feet at all; why in fine the points on which progression depends are even in number.

首先是运动是什么必要的动物进展最低分，第二个为什么血红的动物有四点意见，而不是多，但不流血的动物超过4，一般为什么一些动物是无足，其他两足动物，其他四足动物，其他polypods ，为什么都有一个偶数的脚，如果他们在所有的脚，为什么在精细点上的进展取决于更是增多。
