说明：  滚动轴承故障诊断是机械故障检测中一个重要方面。使用小波包分析和包络分析相结合的方法提取轴承微弱振动信号, 克服了传统包络分析方法易丢失信号有效成分的缺点。包络信号的细化谱较好体现了轴承故障信息。(Bearing Fault Diagnosis of mechanical fault detection in an important aspect. The use of wavelet packet analysis and envelope analysis method of combining extracts bearing vibration signal weak to overcome the traditional envelope analysis method easy to lose the signal disadvantage of the active ingredient. Refinement of the envelope signal spectrum better reflects the bearing fault information.)

都市供求信息网分为前后台的设计，前台主要实现信息的显示、搜索与发布功能。其中信息的显示包括列表显示与详细内容显示，而列表显示，又分为首页面的信息列表显示、查看某类别下所有信息的列表显示和搜索结果列表显示；搜索功能主要包括定位搜索和模糊搜索；后台主要实现的功能为信息显示、信息审核、信息删除、付费设置与退出登录，其中的信息显示功能也分为列表显示与详细内容显示。(Urban supply and demand information network is divided into front and back design, front main achievement of the displayed information, search and publishing. Which displays information including a list of displays and display details, but the list is displayed, the information is divided into the home side s display list, a list of all the categories of information under the display and view a list of search results display Search functions include positioning search and fuzzy search the main function of the background information display, information auditing, information deleted, pay setting and exit the registry, which is also divided into the information display function displays detailed contents list display.)

An all-optical regeneration scheme for DQPSK and QPSK signals using phase-sensitive amplifiers (PSAs) is studied and its effectiveness is investigated through numerical simulations. By leveraging the ability of PSAs to provide phase and amplitude regenerative amplification, we show significant simultaneous suppression of both phase and amplitude noises of (D)QPSK signals under optimized conditions. The reduction in the phase noise variance of a noise-corrupted DQPSK signal obtained by one such regenerative amplification can be as large as 5.5 folds, showing its good potential for distributed optical regeneration of (D)QPSK signals.  2008 Elsevier B.V.
