摘　　要：高精度岩层应力仪的压磁探头在土层安装后,经8个多月的实验观测,对太原附近仅有的两次有感地震(M_L3.5,M_L4.2),仪器均有明显的前兆反映,出现了幅度达数十千帕的应力速率异常。并在震前成功地预报了这两次地震。The piezomagnetic probe of high-precision rock strata stressometer was mounted in earth strata. Through experimentation and observation in 8 mounths, precusory anomalies of the earthquakes ML 3.5 and ML 4.2 nearby Taiyuan regions were observed. The range of rate of stress change are several thousand Pa. Through analysis, we successfully predicted the two earthquakes.
