Charlie and I, it should be emphasized, believe that true trade – that is, the exchange of goods and services with other countries – is enormously beneficial for both us and them. Last year we had $1.15 trillion of such honest-to-God trade and the more of this, the better. But, as noted, our country also purchased an additional $618 billion in goods and services from the rest of the world that was unreciprocated.

当然必须强调的是，查理跟我都相信，真正的贸易，也就是与他国交换货当然必须强调的是，查理跟我都相信，真正的贸易，物与服务的行为，对于彼此都有相当大的益处，物与服务的行为，对于彼此都有相当大的益处，去年光是这类的贸易总额就达1.15兆美元，但除此之外，我们另外又向外国多采购了6，180亿美元兆美元，但除此之外，我们另外又向外国多采购了就达兆美元亿美元的产品与服务，这笔居高不下的数字将引发严重的后果。

The comprehensive survey at present telecommunication industry market, we all know the network telephone has recently experienced the extremely astonishing change in several years, got rid of before was only in a Internet application attached status, now VoIP already has obtained the enterprise as well as the common user user's favour, the gradual substitution originally has used the traditional telephone serves, because VoIP not merely was the new correspondence service project, more importantly to traditional correspondence service vicariousness more and more high, once has opened a gap from here, when the VoIP user are more and more many, at present the traditional telecommunication system the urgent telephone possibly will be the following question which the future VoIP environment will be able to face, Pulls round to move the whole body the question although is unable in the short-term to appear, but this obviously is may foresee.

中文摘要综观目前的电信产业市场，网路电话(Voice over Internet Protocol；VoIP)在最近几年经历了非常惊人的改变，摆脱了以前只是个网际网路应用上的一个附属身份。现在VoIP已经获得了企业以及一般使用者用户的青睐，逐渐的取代了原本所使用的传统电话服务，就因为VoIP不仅仅是新的通信服务项目而已，更重要的是对传统通信服务的替代性越来越高，一旦从这里开了个缺口，当VoIP用户越来越多时，目前传统电信系统之紧急电话将可能是未来VoIP环境会面临到的后续问题，牵一发而动全身的问题虽然无法在短期间出现，但这显然是可以预见的。

The fluctuation of available wireless link bandwidth motivates the study of adaptive multimedia services in wireless/mobile networks This paper focusses on a bandwidth adaptation scheme, which takes the maximum revenue as the objective The optimal bandwidth adaptation algorithm which seeks to achieve maximum revenue is an NP hard problem, because it has to investigate every adaptation case A bandwidth adaptation scheme based on genetic algorithm is proposed, which achieves near optimal total revenue with much less complexity compared to an optimal bandwidth adaptation algorithm Simulation is carried out to compare the algorithm with an optimal bandwidth adaptation algorithm, the results reveal that the genetic algorithm approximates the optimal solution very well

无线链路带宽的快速波动推动了无线/移动网络中对适应的多媒体服务的研究以无线网络系统的利润最大化为目标，研究适应的多媒体应用的带宽适应方案达到利润最大化的最优带宽适应算法是一个NP hard问题提出一个基于遗传算法的带宽适应方案，在算法复杂度大大低于最优算法的同时，获得的利润值近似最优性能分析和实验结果证明了这一结论1 引言因特网和无线/移动通信技术的迅速发展，推动了两者服务的融合无线/移动环境下因特网服务的提供需要解决的一个关键问题是QoS保证提供QoS保证的一个重要技术手段是连接接纳控制 [1] CAC算法的目标是在保证切换连接请求丢弃率满足系

Abstract〕in network environments,information services and core works of university libraries have alternated,while the cataloging of university libraries has changed,which characterizes the socialization of cataloging service,diversification of cataloging objects,and normalization and standardization of cataloging data.catalogers have to perform their new roles such as quality control for cataloging data,cataloging of non-book resources, and building special databases.in order to adapt to the new demand in the library's cataloging,catalogers should transform their roles,improve their special quality,and be active in innovation.

摘 要〕网络环境下，高校图书馆信息服务功能和核心业务的发生转变，编目工作也向编目服务的社会化、编目对象的多元化和编目数据的规范化和标准化等方向发展。编目人员的职能转向书目数据的质量控制、非书资源的编目、特色数据库的建设与信息服务等新的领域。编目人员必须调整专业知识结构，提高业务水平，才能适应网络环境下编目工作的要求。
