The subjacent and lateral strata previously have been compacted . 下卧层和旁侧层先已压实。
The channel is filled with noncompactible sand, or with sand and gravel . 水道内由不可压实的砂或砂砾物质充填。
This mixture is placed into a suitable mould, compacted, and allowed to harden . 这种拌合料灌入合适的模框中,振捣压实,让它硬化。
Although warped by compaction, there is only slight folding of the sandstone lenses . 虽然由于压实作用而弯曲,但砂岩体褶皱很轻微。
In many sedimentary basins the salinity of the formation water increases with depth or compaction . 在许多沉积盆地中,地层水的含盐量随深度或压实作用而增高。
The road is compacted by the traffic if there is not enough money to allow a road roller to be used . 如果没有足够的资金能够使用压路机,就利用来往车辆进行压实。
Such thickening is due to the relative noncompactibility of the sandstone of the bar as compared with the enclosing shale . 这种增厚是由于砂洲砂岩与其周围的页岩具有不同的不可压实性造成的。
