1·The result of evaluation is similar to actual circumstance. This provides the theories for science preventing debris flow and adopting the reasonable measure improvement the debris flow ditches.
评价结果与实际情况基本相符，这为科学防治泥石流和采取合理措施治理泥石流沟提供了理论依据。
2·The existence of the deep ditches on the north side of the under water delta off Subei decides the position fixation of this cold water.
而苏北外海水下三角洲北侧海底深沟的存在决定了这一冷域的位置。
3·Ten soldiers were told off to dig ditches.
十名战士被分派去挖沟。
4·Compared with the simulation result of wastewater-sludge two-phase model, this model is shown to better model the velocities of upper layer and surface layer of oxidation ditches.
通过与污水-污泥两相模型的模拟结果对比发现，采用该模型能够更好的模拟氧化沟上层和表层的流速。
5·Various types of landforms there include mountains, plains, ridges, hills, tablelands, ditches and valleys. The average altitude is above 1,395 meters.
境内地形地貌类型多样，山、川、梁、峁、塬、沟、谷并存，平均海拔1395米。
