孔隙度是指材料内部孔隙体积占总体积的比例,常用于描述岩石、土壤或过滤材料的渗透性。

用法要点

介词用法

porosity 常与介词 of 连用,表示某物的孔隙度;也可与 in 连用,表示在特定材料或环境中的孔隙度。

• porosity of the soil
• high porosity in sandstone
• measure the porosity of a filter

句型搭配

常用句型包括 'have a porosity of...' 表示孔隙度数值,或 'affect/measure porosity' 描述相关动作。

• The rock has a porosity of 20%.
• Temperature can affect the porosity of materials.
• We need to measure the porosity accurately.

语域说明

porosity 是专业术语,主要用于地质学、材料科学、工程和环境科学等学术或技术领域,日常对话中较少使用。

• In geology, porosity is a key property.
• The report discusses soil porosity.
• Industrial applications require low porosity.

基础例句

This sponge has high porosity, so it absorbs water quickly.

这块海绵孔隙度高,因此吸水很快。

The porosity of the soil affects how well plants can grow.

土壤的孔隙度会影响植物生长的好坏。

We tested the porosity of the filter to see if it needs replacement.

我们测试了过滤器的孔隙度,看看是否需要更换。

Low porosity in this clay makes it good for pottery.

这种黏土孔隙度低,适合制作陶器。

高级例句

The study found that porosity significantly influences the hydraulic conductivity of aquifer rocks.

研究发现,孔隙度显著影响含水层岩石的水力传导性。

In petroleum engineering, porosity is a critical parameter for estimating reservoir storage capacity.

在石油工程中,孔隙度是估算储层储存能力的关键参数。

The manufacturer reduced the porosity of the metal alloy to enhance its corrosion resistance.

制造商降低了金属合金的孔隙度,以提高其耐腐蚀性。

常见错误

❌ 错误:The porosity is high in this stone.
✓ 正确:This stone has high porosity.

英语中更常用 'have + porosity' 结构来描述物体的孔隙度,而不是用 'porosity is in',后者听起来不自然。

❌ 错误:We need to check the porous of the filter.
✓ 正确:We need to check the porosity of the filter.

porous 是形容词,意为 '多孔的',而 porosity 是名词,表示 '孔隙度'。这里应该用名词形式来描述属性。

近义词辨析

permeability

permeability 指材料允许流体通过的能力,而 porosity 仅指孔隙体积比例;高孔隙度不一定导致高渗透性,因为孔隙可能不连通。

High porosity does not always mean high permeability; if pores are isolated, fluids cannot flow easily.

porousness

porousness 是 porosity 的同义词,但更口语化且较少使用;porosity 是标准科技术语,在正式语境中更常见。

In scientific papers, 'porosity' is preferred over 'porousness' for precision.
