因特殊的业务需要，某些电话交流需要在第三方的监视下进行，假定某电话交流由甲乙丙三方发起，丙为监听控制方，当甲开始说话时，丙可以不允许乙听，并且开始录音，当甲说完时，丙确定是否可以让乙听，如可以。给乙放录音，当乙说话时，重复以上操作。-because of special operational needs, some telephone exchanges in the surveillance of third parties under the assumption that a telephone exchange was launched by the tripartite B, and C to monitor the controlling party, began to speak when the A, B C can not listen, and began recording at the end when A and C to determine whether or not they can B listen, if we can. B recordings to release, when the B words, to repeat the operation.

摘 : 通过使用 peer-to-peer(P2P)计算模式在 Internet 物理拓扑基础上建立一个称为 P2P 覆盖网络(P overlay network)的虚拟拓扑结构,有效地建立起一个基于 Internet 的完全分布式自组织网络路由模型 集中式自组织网络路由模型(hierarchical aggregation self-organizing network,简称 HASN).分别描述了 HASN 由模型的构建目标和体系结构,并详细分析了 HASN 采用的基于 P2P 计算模式的分布式命名 路由发现和更 算法 HASN_Scale,并在仿真实验的基础上,对 HASN 路由模型的性能进行了验证. -pick : through the use of peer-to-peer (P2P) computing model in the physical topology based on Internet established as a peer-to-peer network coverage (P overlay network) virtual topology, to establish an Internet-based Distributed completely self-organizing network routing model of a centralized self-organizing network Tongxinluo routing model (hierarchical aggregation self-Organization The driver, network, short HASN). HASN were described by the model of the goals and structure. and HASN detailed analysis of the peer-to-peer computing model based on distributed naming and routing algorithm found HASN _Scale and simulation on the basis of HASN routing model the performance

一个用VC做开发平台，用C语言开发的简单电话查询系统，具有添加记录，修改记录，删除记录，查找记录等功能.能帮助了解文件操作。-a VC with development platform, with C-language development simple telephone inquiry system, with added records, change records, delete records, the records search function. To help understand the operating document.

本程序是在单片机c51的基础上实现的数字钟和秒表的功能设计。此设计可是在时钟的基础上实现调表，也可以在时钟和秒表之间实现相互换，P2.0,P2.1,P2.2用于选择不同的数码管亮；P2.4用于调表，按下进入调表模式；p2.5使所调位加1； P2.6按键调表恢复数字计数或者秒表恢复数字钟；P2.7按键进入秒表状态。
