resistivity
名词(Noun)
1. (物理学) 电阻率
The resistivity of a material is a measure of its ability to resist the flow of electric current.
2. (地质学) 电阻率
Resistivity is a measure of the ability of a rock to conduct an electric current, used in geological surveys to determine the presence of minerals or oil.
形容词(Adjective)
1. 电阻率的
Relating to or denoting resistivity.
词语辨析
Resistivity和resistance是两个相关但不同的概念。Resistivity是一个材料特有的属性,用来描述材料的电阻程度。而resistance是一个物体对电流流动的阻碍程度,取决于物体的形状、长度、横截面积以及材料的电阻率。
