%X From the repeted gravimetry data of Dianxi Experimental Field from 2005 to 2009,local differential and cumulate gravity change pictures have been obtained.The study results from the data are as follows.1)The dynamic evolvement pictures of gravity field can generally reflect the movement state of the crustal substance before earthquake.Short-term local effect is obviously reflected by the differential dynamic change,while local tectonic movement and fault structure effect by the cumulate dynamic change.2)A p...
