The reflection spectra of Al0.5Ga0.5As-AlAs distributed Bragg reflector at different incident angle are calculated by transfer matrix method. The reflection spectra curve of p-polarized and s-polarized plane waves vary with a 'V' shape with the rise of the incident angle and the lowest reflectivity is at 49.8°.

Based on seismic source spectrum solution by multi-station and multi-event coda method, applying Brune seismic source model, we have got the source factors and spectra of 48 small earthquakes occurred before and after the Douhe earthquake of October 6 in 1995. The seismic moments, corner frequencies and stress drops are estimated from the spectra, and their correlation and variation with time before and after the Douhe earthquake are discussed.
