1·The proportion of empty space in a rock is known as its porosity.
岩石中空隙的比例被称为孔隙度。
2·Sediment sorting and compaction influence permeability and porosity.
沉积物的分选和压实作用影响渗透率和孔隙度。
3·Extraction of water depends on two properties of the aquifer: porosity and permeability.
水的开采取决于含水层的两个性质：孔隙度和渗透性。
4·This pore space is known as porosity and is expressed as a percentage of the total rock volume.
这个孔隙空间被称为孔隙度，用岩石总体积的百分比表示。
5·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。
6·Porosity is important for water-storage capacity, but for water to flow through rocks, the pore spaces must be connected.
孔隙度对地层储水能力尤为重要，但要让水能够从岩石中流出，孔隙之间必须相互连通。
7·With their enormous size and weight, today's farm machines have significant downsides: they compact the soil, reducing porosity and killing beneficial life, meaning crops don't grow so well.
由于庞大的体积和重量，现在的农业机械有显著的缺点：它们会把土壤压实，降低土壤孔隙度，杀死有益的生命，这意味着农作物不会长得太好。
8·The study result was verified by porosity testing.
分析结论通过孔隙率检验得以证实。
9·Welding porosity is the main defect during laser welding.
焊接气孔是粉末冶金材料激光焊接的主要缺陷。
10·The mechanical compaction is the main cause of porosity loss.
压实作用是造成砂岩孔隙度降低的最主要因素。
