Based on it, energy coupling grates are designed and fabricated for spin wave (Winter mode) excitation within domain walls, and successful result is obtained in the coupling between electromagnetic field and spin waves.

Based on the two main functions of GIS, the spatial interpolation and the raster overlay(algebra algorithms), a method has been developed to generate types and distribution of surface sediments automatically from results of the in-door grain-size analyses, and the Cao-Fei-Dian coast has been taken as a case .
