1. As the water is pumped out, the vacant space left is compacted by the weight of the earth above. 当水被抽出来时，剩余的空间被上层的泥土填满压实。
2. The more poorly sorted or the more tightly compacted a sediment is, the lower its porosity and permeability. 沉积物分选越差或压实越紧，其孔隙度和渗透率就越低。
3. The slush is compacted by an unknown mechanism, and solid, bubble-free ice is formed from water high in soluble organic substances. 半融雪通过一种未知的物理过程被压实，而固态、无气泡的冰是由富含可溶性有机物的水形成的。
4. Snow falls as hexagonal crystals, but once on the ground, snow is soon transformed into a compacted mass of smaller, rounded grains. 雪以六角形晶体的形式落下，但一旦落到地面，雪很快就会变成一团更小、更圆的颗粒。
5. The influence of stabilizers and soil properties on the strength of stabilized, compacted earth is investigated. 研究了稳定剂和土壤性质对稳定的压实土的强度的影响。
