In terms of the instrument intensity distribution，first impulse orientation of seismic velocity records，Sg shear wave split characteristics of a serial of near-regional earthquakes and records of strain and helium gas in deep holes nearby epicenter，we discuss two noticeably felt earthquakes of MS4． 0 and MS3． 5 in Baodi County in 2012 and reveal some gestation traits of these earthquakes． Although the magnitudes of 2 earthquakes are a little small，some stress changes may appeare in the crust in seismogenic process，in the form of an accelerated NEE orientation pressure and NNW dilation half a year before main earthquake． These states alleviated after MS3． 5． In the time interval between two earthquakes，the regional underground accumulated stress may not be fully released． The state change of local underground micro-cracks led to record more deep rare gas． After MS3． 5 micro-cracks closed again，the polarization azimuth of seismic quick shear wave returned to the NEE direction． In the near epicenter region，the abnormal characteristics of strain record，seismogram and deep hole liquid had a certain consistence of observation in time and space．
