We prove the reducibility of analytic multipliers M_(φ)with a class of finite Blaschke products symbolφon the Sobolev disk algebra R(D).We also describe their nontrivial minimal reducing subspaces.
文摘针对GIL综合管廊施工期间的监控量测问题,提出基于物联网技术的安全监测与预警解决方案,建立远程在线信息化监测和数据处理系统:以自动化测量仪器和岩土类传感器为感知层,实现形变信息的实时采集;以串口通信、GPRS(general packet radio service)和Internet为网络层,实现远程控制和数据传输;以集成化的云平台和应用程序(application,APP)为应用层,实现监测信息的存储、处理、分析、挖掘、共享与发布。工程应用表明,该系统能够实时、可靠、高精度地监控电力隧道,确保综合管廊施工安全。
