本文从地震检波器性能指标和稳定性的要求着手，论述了应用钕铁硼永磁材料对地震检波器性能及稳定性造成的影响和解决应用中存在问题的观点与方法。

As is well known, geologists can measure and locate an earthquake with a seismometer.

众所周知，地质学家能用地震检波器来测量和定位地震发生的等级和位置。

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。

All the above researches are very important to the usage of thelaser Doppler technique in seismic prospecting.The laser Doppler frequency shift of scatters and diffract grating was discusstheoretically.
