Porosity
词性及含义
“Porosity” 是一个名词,主要指材料中的孔隙度或空隙的程度。它通常用于描述岩石、土壤、金属等材料的结构特性。虽然“porous”是其形容词形式,但两者的含义并无显著差别,都是与孔隙有关的性质。
词语辨析
在科学和工程领域,“porosity”常用来分析材料的流体渗透性,而“porous”则更强调材料本身的结构特性与用途。
词汇扩充
近义词:permeability, voidness
反义词:density, solidity
词典参考
Collins Dictionary: "Porosity refers to the quality of being porous or having many small holes." 孔隙度是指材料多孔或有很多小孔的特性。
Oxford Dictionary: "Porosity is the ratio of the volume of voids to the total volume of the material." 孔隙度是孔隙体积与材料总体积的比率。
用法
在不同的科学和工程领域中,“porosity”被广泛使用,尤其是地质学、土壤科学和材料工程。
