ABSTRACT Over the last few years much attention has been paid to the development of the technologies for Community Antenna Television networks. New technologies that can be used to support data communication service over CATV networks are developed. The new Hybrid Fiber Coaxial technology is spreading out rapidly in CATV networks. The usage of fiber provides large bandwidth and thus enables some new services to be delivered along with television broadcast. The CATV networks are expected to support diverse traffic with various service requirements.

随着新技术的不断发展，人们希望能够利用有线电视网络提供新的业务，HFC技术在有线电视网络中的广泛使用使得有线电视网络的带宽增加，也使得有线电视网络除电视广播外还能够提供其他的服务，这些服务的服务质量要求各不相同，如：数据服务要求低的丢失率，对延时的要求较低；而语音服务可容忍一定的丢失，但对延时、延时抖动有严格的要求，因此需要开发新的协议。

To solve problem of electromagnetic pollution, a Ni-based composite shielding coating has been prepared based on the electromagnetic shielding principle. Nickel and metal fiber are used as composite fillers, and acrylic resin as binder. The coating is designed for use in some community antenna television nets and shielding workshops.

针对日益严重的电磁环境污染问题，根据电磁波屏蔽材料对电磁波作用原理，用镍粉和金属纤维作为复合填料，以丙烯酸树脂作粘结剂，按照涂料制备的方法，制备了一种能屏蔽电磁波的复合涂料。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
