摘　　要：牡丹江台钻孔应变仪自安装以来,受到很强烈的外界干扰,记录情况一直不好,没有取得理想的记录效果,仪器也没有发挥应有的功效。本文用小波方法对钻孔应变记录到的数据进行分析处理,查找原因,并提取有价值的信息,在现有情况下充分利用记录数据,为进一步对地震监测分析做准备。Since the installation of borehole strain has been very strong interference in Mudanjiang station, the record has been poor. And the record does not achieve its desired effect. In this paper, wavelet method was used to analyse the borehole strain records, to extract valuable seismic information, and to make full use of the existin~ case record data for further monitoring and analysing of earthquake.
