| 摘 要： | 根据岩石强度的差异，组合成不同类型的试样，采用不同的加力方式，模拟不同的地震孕震类型，用多功能高频地震勘探仪和光线示波器对比记录各测点的应变变化。实验结果发现，在岩石主破裂前，不同类型试样各点应变都出现趋势性变化；除软包体型试样外，各点应变除趋势性变化外，都出现应变突变。据此提出应变成核概念。

| Abstract: | According to the difference of rock's strength, the different samples are combined. The different force-loading patterns are used to simulate the different seismogenic models. A multi-functional seismic prospecting-meter with high frequency and a ray-oscillometer are used to record for comparison of strain variation in each measuring point. The results discover that the tendency variation of strain appears in different types of samples before the major rupture. Besides the tendency variation in each point, the strain mutation appears except the sample of soft inclusion, based on which the concept of strain nucleation is put forward. |
