Cavernous porosity can take the equidimensional form of vugs or follow channels, but the void dimensions are measurable in meters . 溶洞孔隙可呈等尺度的溶孔形态，或者呈溶沟形态，但空间大小是以米度量的。
These canals are frequently excavated through rock, and require tunnels, flumes, syphons, aqueducts and open concrete-lined channels . 这些水渠往往要凿通岩石，并需要地道、引水沟、弯管、渡漕和混凝土水道。
It is probable that local furrows and wider depressions, caused by buckling of the accumulated silicate layers during tectonic movements . 可能有局部沟豁以及宽的坳陷，在构造运动过程中由堆积的硅酸盐层弯曲造成。
The weight of a deltaic pile of sediment may be so great as to depress the earth's crust, thus forming a moat around the depocentre . 三角洲沉积物堆积的重量可以大到使地壳下沉的程度，因此在沉积中心周围形成一条深沟。
Batteries may be constructed with one-piece cover, with double flanged seal channels on the under side, into which sealing compound is poured . 蓄电池可以是整体盖结构的，在盖底边上有一个供灌注封口剂用的凸出的双边封沟。
Women scream after their children for loitering in the gutter, or, worse still, against the husband who comes reeling from the gin shop . 娘儿们看到孩子在污水沟里打滚，更坏的是，看到她们的男人喝得醉醺醺的，在街上摇摇摆摆晃晃走来，于是使尖声叫骂。
The difficult-to-describe flow of gas, with its large deviations from plug flow and the bypassing of solids by bubbles, represents an inefficient contacting system . 气体流动状态难以描述，与活塞流离较大，由于气泡产生而使固体颗粒发生沟流，这些都表示接触效率降低。
