声发射（AE）法在岩石监测中的应用 骨折迄今为止还没有成功， 来解释记录的波形 这项实验研究 直接解决的困难，在AE方法，通过使用大 试样（尺寸为0.3 x 0.3 x 0.6米），以减少 反射波，并提供记录相对较长AE的时间 事件 本研究将采用现代处理技术， 量化AE方法应用于监测断裂过程， 岩石化学分析方法 将采用甚高频换能器， 将使用超宽带记录仪记录波形， 高保真度 数字化和处理将在 先进的规模，以确保完整和彻底的分析AE数据。

The application of the acoustic emission (AE) method to monitor rock fractures has thus far not been successful because of the difficulities in interpreting the recorded wave forms. This experimental research directly addresses the difficulties in the AE method by using large specimens (0.3 x 0.3 x 0.6 meters in size) to reduce the effects of reflected waves and to provide time for recording relatively long AE events. Modern processing will be employed in this research to quantify the AE method as applied to monitoring the fracture process in rocks. Very high frequency transducers will be employed and an extremely wide band recorder will be used to record the wave forms with high fidelity. Digitizing and processing will be performed on an advanced scale to ensure complete and thorough analysis of the AE data.
