【摘要】 根据云南地震目录,尝试用频谱分析法对云南45年期间的地震活动时序特征进行研究.利用震级和能量时间序列特征分析地震活动的平静与活跃期,并通过时间域和频率域的转换,结合云南地震活动的历史背景讨论了云南地震的主要活动周期,并且对云南地震活动的时间特征及未来地震活动可能性进行了探讨.更多还原

【Abstract】 The essay is trying to deal with the data of seismic motion of Yunnan over the recent 45 years using frequency spectrum analysis,on basis of earthquake catalogue of Yunnan.The quiet and active period of seismic motion are studied utilizing sequential characteristics of magnitude and energy,and the primary period of seismic motion here is discussed by conversion of time domain and frequency domain,together with historical background of seismic motion of Yunnan.Then the characteristics and future possibilities of seismic motion of Yunnan are investigated.更多还原
