摘　　要：本文详细研究了一次地震发生后其继发地震的时空免疫性特征、研究结果表明，青海地震的免疫性特征是十分明显的，它对进一步认识地震发生的时空特征有着重要的意义。相邻两次地震的时间间隔，和空间距离ｄ的临界直线关系为ｄ∞τ（－１．０），其迁移速率ｖ的关系为ｖ∞τ（－２．０）。这也是齐夫（ｚｉｐｆ）法则所约定的分维值，十分类似于１／ｆ谱。我们形象的称ｄ∞τ（－１．０）分布是“随机音乐”；ｖ∞τ（－２．０）分布是“布朗音乐”。In this paper,time-space immunity which occured next one after an earthquake occured was detailed studied. The results show that characteristics of immunity of Qinghai earthquakes is remarkable. It has significant to further understsnding seismic time-space teature.Critical direct line relation between time interval τ and space distant d of adjacent is d∞ τ(-1.0), relation between migrate rate v and τ is v∞ τ(-2.0). the fractal dimension value 1.0 is correspond to zipf law, It is similar to 1/f spectrum. We vivid called that d∞τ(-1.0) is“ Random music”,v∞τ(-2.0)is “Brownian musics”.
