Abstract:
        Acoustic emission (AE) phenomenon will occur during the production and propagation of internal cracks, and failure in brittle rock. Under uniaxial loading, the complete stress-strain curves and waveform data were obtained. The Welch spectrum estimation and Cubic spline interpolation method were used to analyze the evolution of F, R values (peak frequency, energy percentage) of AE. The results show that F-values are maintained at 100±20kHz, and the peak points of F and R above 25% which can be used as a precursor to rock failure that their waveform are burst-type. The combined analysis of stress and F, R supplies a more accurately method of predicting the occurrence of rock burst. © (2013) Trans Tech Publications, Switzerland.

我的773检索了，可是到现在没有收到论文集，会友们，你们收到了木 有？难道会务组为了省钱不给我们。我们年度考核要查看原文呀，么办呢？
