单词 Electrical conductor
释义

Electrical conductor

原声例句
Crash Course 综合篇

So if both N-type and P-type crystals are both electrical conductors, why do we call them semiconductors?

“如果 N 型和 P 型晶体都是导体,那为什么我们叫它半导体?”

当月 CNN 10 学生英语

And those changes generate currents which can damage power grids, satellites, anything that has an electrical conductor involved.

这些变化产生的电流会损坏电网,卫星,任何涉及电导体的东西。

Life Noggin 科普精选(双语)

The first one, the E1 pulse, is a fast, but intense pulse that can quickly induce dangerously high voltages in electrical conductors.

第一种是E1波,它是一种快速而强烈的脉冲,能迅速地在导体中诱发危险的高压。

《分钟地球》趣味科普(精选双语)

In that case, whether you're naked or in costume, your body, unfortunately, happens to be a better electrical conductor than both air and soil, so it provides a great shortcut for traveling current.

在这种情况下,无论你穿没穿衣服,很不幸,你的身体恰巧比空气和土地的导电性更好,这就为流动的电流创造了良好的捷径。

TED演讲(视频版) 2019年4月合集

Again, you take a flexible polymer such as our Ziploc bag, you fill it with an insulating liquid, such as olive oil, and now, instead of the glass plate, you place an electrical conductor on one side of the pouch.

同样,你拿一个柔性聚合物, 比如我们的 Ziploc 袋子,你在里面装满绝缘液体, 比如橄榄油,现在,你把一个电导体放在袋子的一侧, 而不是玻璃板。

导体

导体为能够让电流通过的材料,依其导电性,能够细分为超导体、导体、半导体及绝缘体。在科学及工程上常用利用欧姆来定义某材料的导电程度。它们使电力极容易地通过它们。

当电流在导体内流过时,事实上是因为导体内的自由电荷(在金属中的自由电荷是电子,而在溶液中的自由电荷则为阴、阳产生漂移而造成的,根据材料的不同,自由电荷的漂移方式也不相同:在超导体中,电子几乎不受原子核的干扰而能够快速移动;而在导体内电子的移动受限于该材料所造成的电子海的能阶大小;而在半导体内,电子能够移动是因为电子-空穴效应;而绝缘体则是电子受限于分子所构成的共价键,使得电子要脱离原子是非常困难的事。因此,没有绝对绝缘的绝缘体,只要有足够大的能量就可以使电子得以通过某绝缘体。

Electrical conductor 导体

Overhead conductors carry electric power from generating stations to customers.
A piece of resistive material with electrical contacts on both ends.
Conductor eléctrico de cobre.
Leiter 1. Klasse, Kupferkabel

In physics and electrical engineering, a conductor is an object or type of material that allow the flow of electrical current in one or more directions. A metal wire is a common electrical conductor.

In metals such as copper or aluminum, the mobile charged particles are electrons. Positive charges may also be mobile, such as the cationic electrolyte(s) of a battery, or the mobile protons of the proton conductor of a fuel cell. Insulators are non-conducting materials with few mobile charges that support only insignificant electric currents.
