摘要
基于几何映射原理，对两个不同地区之间的“震级距离对”进行等烈度条件下的全对称交换。所得结果，可以直接用于研究地区地震动衰减关系的外推。文中最后给出了一个算例，并对三种不同交换方法的“截止域”迸行了讨论．
Based on the principle of optical image, in this paper, a pair of magnitude-displacement between two regions are full symmetrically transformed under equal conditions of seismic intensity in order that the attenuation function is extended to the study region. Finally, the cut-off domain in the transformed magnitude and displacement is discussed by using of a typical example.
