摘要

实验数据是用在花岗岩试样上施加单轴载荷直至其破裂时所记录的声发射的两个幅频谱来解释的。解释过程基于盘状裂缝模型。这些结果使我们能够分析试样结构参数的变化，以及在记录光谱的时间间隔内的断裂过程。

A Study of Fracture in a Granite Specimen Using Observations of Acoustic Emission

Experimental data were interpreted using two amplitude–frequency spectra of acoustic emission as recorded during the application of a uniaxial load to a granite specimen until it fractured. The interpretation procedure was based on the model of disk-shaped cracks. The results enabled us to analyze the variation in structural parameters in the specimen, as well as the fracture process during intervals between the times when the spectra were recorded.

期刊介绍： Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
