| 摘 要： | 本文介绍利用单台小地震资料确定台站所在区域应力场的一种方法以及对于红山地震台和沙城地震台两个区域所获得的结果。 在弹性介质中,如果发生了形状和体积的变化,即应变,则介质内务部分之间将有相互作用力,叫做应力。这种应力一般表示为张量

| Abstract: | A method for determining the stress field of a region from weak earthquake data recorded at a single station located in the same region has been described.The results of applying this method to two regions in Hopeh （河北） Province are given,and some implications of the obtained stress field are discussed. |
