The most activearea of the earth surface is plate boundary, where most earthquakes and volcanic distribute on, while the region within the plate is relatively stable.
板块边界是地球表面最活动的地带，绝大多数地震、火山分布于活动带上，而板块内部则是相对稳定的地区。

The first unipolar plate and the second unipolar plate are aligned to dispose the first activearea adjacent the second active area.
第一单极板 和第二单极板对准以邻近第二活性区布置第一活性区。

There is not the contemporary plate-tectonic system in the researching area. However, the active forms of polycycle trough (basin) developed in the area.
