| 摘 要： | 为研究地面表层土壤中水分含量变化与震前记录到微震和极微震的关系，进行了声波与表层土壤含水量变化的实验．实验的目的是探讨震前微破裂引起的声波能否改变土壤表层的水分含量，从而建立起遥感图像中的热异常信息与孕震关系．通过实验发现，声波对土壤作用使得原本自然蒸发呈降低趋势的湿度值呈上升趋势，而土壤表面的温度呈下降趋势．

| Abstract: | In order to investigate the relation between the water content changing of surf ace soil and micro-quake recorded before earthquakes, we carried out a simulation e xperiment in laboratory. Its purpose is to explore whether the acousti c wave generated by micro-fracturing before earthquake are able to chang e water content of surface soil, so as to understand the relation between therm al anomaly in the remote sensing image got from the seismogenic area and the coming earthquake. The result of the experi ment shows that when the acoustic wave enters into the surface soil the water content here increases on the background of decreasing because of natural evapor ation. In the meantime, temperature here decreases. |
