【摘要】 随着国内外各个仪器厂家不断推出高性能高质量的地震仪器 ,在不断采用各种新技术新方法的同时 ,对过去沿用多年的一些老技术老方法也不断有新的认识 ,模拟滤波器就是其中一例。文章从地震仪器发展史 ,模拟滤波器理论 ,地震反射波原理以及目前各仪器厂家所持观点等几个方面深入探讨了目前地震仪中去掉模拟滤波器的原因。最后针对野外勘探的干扰问题提出几点看法。更多还原

【Abstract】 In order to meet the development of geophysical exploration market and technology, each instrument factories continually make high performance and good quality instruments. One may produce new recognition to old technology and method while using new technology and method, the analog filter for one. The paper deeply inquires into the reason about discarding analog filter from nowaday instruments in respects of seismometer developing history, theory of analog filter, principle of reflecting wave and viewpoint of instrument factories. Finally the paper proposes some views about interfering waves in field exploration.更多还原
