J. Cent. South Univ. (2021) 28: 1843-1856 DOI: https://doi.org/10.1007/s11771-021-4734-6 AE waveform characteristics of rock mass under uniaxial loading based on Hilbert-Huang transform LI Xue-long..., albeit being more distinct at the beginning and at the end of the compaction phase. Since the effective duration of the waveform is short, its resulting energy is small, and so there is a relatively high......
