【摘要】 针对大陆地震观测中的连续震颤波,根据其信号特征和观测特点,在准确识别震颤波信号、提高信噪比、缩小信号范围等原则基础上,参考国际上对间歇式震颤的定位方法,对信号的识别、处理及定位方法和技术进行整合、改进,提出对这类信号采用的定位技术和方法流程,并应用该方法对中国大陆地震观测中几个由台风引发的连续震颤波信号进行定位和效果检验。结果表明,这些技术和方法是可行的,其定位结果合理可信。更多还原

【Abstract】 This paper introduces the signal characteristics and the observed characteristics of continuous tremor waves in continent seismic observations.On the basis of identifying and extracting principles of tremor wave signals,improving the signal to noise ratio,reducing the analysis time scale,referencing international intermittent tremor positioning methods,improving the methods of signal identification,processing and positioning methods,we propose technological approaches and processes for positioning these kinds of signals.Further,we apply it to several tremor wave signals caused by typhoons in mainland Chinese seismic observation for positioning and effect testing.Results show that these technological approaches and processes are viable and that the positioning results are reasonable and believable.更多还原
