模态对滑动─—地震检波器面临的问题
The set-up of a conventional seismometer is a couple of permanent magnet and coil, which has a few troubles such as electromagnetic interference, permanent magnet′s non-linearity, and small dynamic range.
传统地震检波器为“永磁动圈”式电磁检波器,在信号捡取过程中易受电磁干扰,存在非线性、动态范围小等问题。

Several Problems in the Use of Geophone
地震检波器使用中应注意的几个问题
An earthquake with a magnitude of less than 2.0 is so slight that usually only a seismometer can detect it.
小于2.0震级的地震非常轻微，通常只有地震检波器才能探测到。
