To solve the problems in knowledge management system （KMS）, such as information sharing, the ability to extend and re-engineer, and the reusable ability of legacy systems in distributed and heterogeneous environments. This article presents a method based on agent and ontology of designing KMS. This method consists of two agencies. One is knowledge agency with three agents supporting knowledge management process. The other is application agency with three agents supporting knowledge application. In this method, ontology is used to represent the knowledge in knowledge base and the content in the message exchanged among agents. To demonstrate the advantages of this method, experiments have been carried out and the results imply that this method is efficient and effective for small and medium-size enterprises to design KMS.

The Journal of China Universities of Posts and Telecommunications 2000年第4期7卷 62-67页

作者： LI Xiang ming, yue Guang xin, YIN Chang chuan (School of Telecommunication Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, P.R. China) School of Telecommunication Engineering Beijing University of Posts and Telecommunications Beijing 100876 P.R. China

A carrier recovery method of the power spectrum center difference adapting to the mobile channel of the MC CDMA system with serious Doppler shift using double pilots is presented. In the transmitter, two pilots of equal frequency distance to the carrier with one putting on the left position and the other on the right position of the carrier frequency are used. Even if a continuous sine wave is transmitted, the power spectrum is expanded to a Doppler band in the receiver owing to the multi path transmission and the Doppler shift. The pilot spectrum is made to pass through two narrow band filters which are transformed to the base band with local carrier wave in the receiver. The frequency difference between the local carrier and the transmitter carrier is obtained when the difference of the gravity centers of the two pilot spectra is computed.

采用矢量有限元法实现了三维电磁扩散场数值模拟,并成功将其应用在大地电磁的正演研究中.为灵活精确地拟合起伏地形和地下不规则构造,采用由不规则四面体单元组成的非结构化网格,可根据模型设计的需要调整网格的大小.引入了基于二次场理论,将解析的一次场从总场中扣除,直接计算二次场,使得误差仅局限于相对较小的二次场,以提高总场计算精度.常规的节点有限元法不满足电性分界面上法向电场不连续和无源区单元内电流密度无散,违反麦克斯韦方程组.为克服节点有限元法的弊端,使用矢量有限元法求解基于二次电场的偏微分方程.另外,在算法设计中,考虑了磁导率参数的变化,可以模拟磁导率不均匀的模型.通过与COMMEMI模型已发表的结果对比,证明了本文算法的正确性和精确性.为突显非结构网格优势,计算了椭球异常体模型和任意地形模型的MT响应,并详细讨论了地形和磁化效应对三维数值模拟结果的影响.

磁性异常对时间域航空电磁观测数据有明显影响,但关于同时存在电导率和磁导率异常的时域航空电磁三维正演模拟的工作还未见报道。本文发展了考虑磁化效应的频率域电磁三维矢量有限元数值模拟技术,在此基础上,利用时-频转换实现同时考虑地下电导率和磁导率异常的三维时间域航空电磁正演计算,理论模型验证了该算法的准确性和稳定性。结果表明:磁化异常显著增强了时间域航空电磁响应强度,特别是在强磁性环境背景下,时间域航空电磁的响应值在良导体中反而比在高阻体中更小,这个新现象对具有潜在异常磁导率地区的时间域航空电磁数据解释及其应用有重要影响。
