In Cenozoic typical back-arc rift basins are formed in ne China where is the back-arc area of Pacific plate subduction zone.
新生代，东北地区作为太平洋板块俯冲带的弧后地区，形成了典型的弧后裂谷盆地。
The effects of cutting area, contact arc length, the geometry of cutting face, back dip angle of PDC cutter and rock performance on force of PDC cutter breaking rock were simulated experimentally.
试验模拟了切削面积、接触弧长、切削面形状、切削齿后倾角和岩石性能对PDC切削齿破岩受力的影响。
The conversion result shows that the cold asthenosphere sinks in large scale along trenches and ocean-sides and hot asthenosphere rises greatly along the arc-back area.
结果显示，在海沟及其洋侧冷的软流层发生了大规模的沉降，而弧后热的软流层则强烈抬升。
