J. Cent. South Univ. (2021) 28: 2463-2471 DOI: https://doi.org/10.1007/s11771-021-4739-1 Periodic electromagnetic signals as potential precursor for seismic activity YONG Shan-shan(雍珊珊)1, WANG Xin...-Verlag GmbH Germany, part of Springer Nature 2021 Abstract: Electromagnetic signals may be a promising precursor to seismic activity which has been observed in many case studies in past decades. However......
(Mo-Cu) composites were fabricated by infiltrating liquid copper into molybdenum fibrous preform. By controlling the relative density of molybdenum fibrous preform, the composition of Mo-Cu... on the composition, physical and mechanical properties were investigated. The results indicate that molybdenum fibrous preform obtained by non-woven technology with mould pressing formation has wider range......
