借助地震空区Ｒ－ ｔ图分析原理，以新疆８ 次６ 级以上强震为例，分析研究强震前加、卸载地震的异常分布特征。结果表明：８ 次强震中有６ 次地震，震前在震中周围出现明显的加载地震相对集中分布或加载地震围空异常区，异常区出现于震前１ 年到１ 年半左右，其半径尺度为５０～９０ ｋｍ 。
With the principle of R- t map analysis in the seismic region, taking the eight strong earthquakes above M6.0 in Xinjiang as an example, the anomalous distribution features of earthquakes before and after the strong earthquakes are analyzed and studied. The results show that there are 6 earthquakes in 8 strong earthquakes. Before earthquakes, obvious loading earthquakes occur relatively concentratedly distributed or anomalous areas of the earthquakes are loaded, and anomalous areas appear about 1 year to 1 year and a half before earthquakes. Their radius scales For 50 ~ 90 km.
