PPP挑战握手认证协议(CHAP)，PPP【1】提供了点到点链路传输多协议数据报的标准方法。 在PPP中也定义了一种可扩展的LCP，允许协商认证协议，从而可以在进行网络层 协议传输之前对对端进行认证。 本文定义了一种PPP认证方法，该方法利用随机“挑战”和依据“挑战”和密钥 计算出的加密哈希“应答”来完成认证。 -PPP Challenge Handshake Authentication Protocol (CHAP), PPP [1] provides a point-to-point link multi-protocol data transmission of standard methods. In PPP also defines a scalable LCP to allow consultations authentication protocol, thereby conducting transmission network layer protocol before the end-to-end authentication. This paper defines a PPP authentication methods, The method using random "challenge" and the basis for "challenge" and calculated key encryption Hash "responsive" to complete certification.

太原理工大学硕 士 学 位 论 文 摘 要 网络缓存（Web Caching）把经常访问的网络对象在访问开 销较少的网络节点上存一个副本，当用户再次访问这些对象时， 可以直接从这个开销较少的网络节点上得到满足。从而在有限 的带宽内，达到缩短用户等待时间、提高网络性能和网络可扩 展性的目的，对于提高Internet 访问效率具有重要意义。-Taiyuan University of Technology master"s degree thesis Abstract network cache (Web Caching) frequent visits to the network to visit the object of the less expensive network nodes onto a copy, when users visit these objects, directly from the overhead less network nodes to be met. Thus the limited bandwidth, which can shorten the waiting time for customers, improve network performance and network scalability for the purpose of improving the efficiency of Internet access is of vital significance.

心率指心脏每分钟搏动的次数, 它能够反映心脏的工作状态。正常心率决定于窦房结的节律性, 成人静息时约60～100 次/ min , 平均约75次/ min。心率可因年龄、性别及其他因素而变化。初生儿心率约130 次/ min , 随年龄增长而逐渐减慢, 至青春期乃接近成人的心率。女性心率比男性稍快 运动员心率较慢。成人安静心率超过120 次/ min 者, 为心动过速 低于40 次/ min 者为心动过缓。心率受植物性神经和体液因素调节。-Heart rate means the number of pulse per minute, it can reflect the work of the state of the heart. Normal heart rate determined by the rhythm of the sinoatrial node, resting adult is about 60 ~ 100 times/min, an average of about 75 times/min. Heart rate may be due to age, gender and other factors change. Heart rate of newborn infants of about 130/min, growth has gradually slowed down with age, to adolescence adult heart rate is near. Women slightly faster rate than men athletes slow heart rate. Quiet adult heart rate over 120 times/min, and for the tachycardia less than 40 times/min for bradycardia. Heart rate by the plant regulate neural and humoral factors.

本书使学生掌握传感器的基本原理、结构、用途、输出特性、误差分析及补偿方法、性能指标及优缺点等。-This book so that students master the basic principles of sensors, structure, purpose, output characteristics, error analysis and compensation, performance indicators and the advantages and disadvantages and so on.

1、 生产者―消费者问题是一种同步问题的抽象描述。 2、 计算机系统中的每个进程都可以消费或生产某类资源。当系统中某一进程使用某一资源时，可以看作是消耗，且该进程称为消费者。 3、 而当某个进程释放资源时，则它就相当一个生产者 -one, producer-consumer problem is a problem of synchronization of the abstract description. 2, the computer systems of each process can consumption or production of certain resources. When a process system using a resource, can be seen as expendable, and the process known as consumers. 3, and when a process to release resources, then it is a producer
