The narrow-band PAS system opened in each cities presently and the LMDS broad-band technology in process of test network construction are introduced.

Research on ISAR Multi-target Imaging for Monopulse Narrowband Radar;

Research the Key Technique of the Narrowband Video Conference;

The paper introduces development of narrowband SPA-H weathering steel by adopting the process of "converter-narrowband" instead of "EAF-narrowband".

Adaptive Noise Canceling for Spread Spectrum Systems with Narrow Band Jamming;

Application of hierarchical multi-phase C-V method based on narrow band to MRI image segmentation;

High speed MODEM design for narrow band communication

A New Calibration Method of Narrow-band Radiation Pyrometer;

The possibility of UHF (ultra high frequency) method used in partial discharge detection in GIS is analyzed, and the UHF sensor, simulating passive filter, detecting the method of wide-band and narrow-band are studied, in order to avoid interferes of low-frequency.

In light of the quality problems of skin formation,pitting and so on of Q195 narrow steel strips during cold rolling,based on production practice,follow-up tests on billet surface,macro-examination,strip surface pickling were specially made.
