【摘要】 应用周期 -频度谱方法对黑龙江省数字地震台网资料进行处理 ,给出了矿震、电缆应力释放、震源车作业、火山地震等振动的周期 -频度谱和链波指数 ,并对构造地震和爆破的链波指数进行了讨论。针对港震公司的数字地震记录格式编写了专门的处理程序 ,为数字地震台站开展周期 -频度谱分析提供了有力的工具。更多还原

【Abstract】 The earthquake data of the digital network in Heilongjiang had been researched by period-frequency spectrum, gave period-frequency spectrum and ripple exponent to each typical vibration. The procedure have been edited that deal with the data form by the Gangzhen Co. recording. Hence, we provide a powerful tool that is used to researched period-frequency spectrum.更多还原
