| Abstract: | In rock mechanics experiment, the source location methods of acoustic emission(AE) is an important aspect of experimental AE research. On the basis of summarizing predecessors' work of experiment facility and location algorithm, the advantages and disadvantages of some location methods were analyzed, which were frequently applied in seismological laboratories, and the possible direction of AE location development in future was pointed out. Finally, the difficulties which must be overcome to improve the precision of AE source location was discussed. |
