例文
- Under magnification one can observe many parallel shear planes of tectonic origin.
- Consider a parallel shear flow U ( z ) in the x direction, which varies only in the cross-flow direction z.
- Characteristics of these natural fractures vary by lithology, diagenesis, and structural position, with fracture heights being greater in the more homogeneous formations and bed-parallel shear being best developed on the steep forelimb of the anticline.
