为了实现短双折射光纤环镜(Bi-FLM)应变传感器的在线测量,理论推导得出通过任意连续的2个相邻波谷波长、2个相邻波峰波长及其双折......

This paper shows the presence of noises and technique to reduce these noises during the surface wave analysis. The frequ......

Noise attenuation is necessary before and after stacking in the seismic data processing. We describe the filtering metho......
