日本地震学家楠懒、勤一郎等人自1979年以来在岩石实验中已经研究出一套声发射定位系统(AE location system)。这一系统的实现使岩石实验在 AE 方面进入了新的阶段。他们利用这一系统进行了一系列重要的研究工作:首先,在单轴压力下解决了 AE 定位问题,从而获得 AE 的震源分布,并把重点放在AE 的时间分布、源机制解和空区形成机制上;其次,在三轴压力下研究波速变化问题,重点 Japanese seismologists Nan Lao, Qin Yi Lang et al. Have developed an AE location system in rock experiments since 1979. The realization of this system has brought rock experiments into a new phase in terms of AE. They used this system to conduct a series of important research work. First, the AE localization problem was solved under uniaxial pressure to obtain the focal distribution of the AE, with a focus on the time distribution of the AE, the solution of the source mechanism and the free space Formation mechanism; Secondly, under the triaxial pressure wave velocity changes, the focus
