Therefore, the wave equation pre-stack depth migration, a method starting directly from the rollingsurface, is discussed.
为此,探讨了直接从起伏地表开始的波动方程叠前深度偏移方法。

Damage state: when in the installation and removal of such use to the raceway and the rollingsurface wounds caused by the axial linear.
损伤状态:当在安装和使用这种搬迁到滚道和滚动表面轴向线性造成的创伤。

As chemical precursors stream onto the surface of a rolling metal or plastic substrate, they react with one another to form a network of nanoparticles.
