关键区别-传导与感应
传导和感应的关键区别在于,在传导中,能量是通过使用物质来传递的,而在感应中,不需要任何介质或接触来传递能量。
什么是传导(conduction)?
传导是以热或电的形式传递能量的过程。在热传导中,介质中的原子振动并传递热量,换句话说,热能。在热传导中,介质中的原子通过振动主动传递能量。只要存在温度梯度,热能就在原子间流动。大多数好的热导体是固体。它们紧密堆积的结构有助于固体成为有效的导体。但应注意的是,并非所有固体都是好的导热体。传导是传热的一种方式,热可以通过对流和辐射来传递。记住,我们只加热锅的外部,而不是内部。锅上任何好吃的东西都可以煮熟,因为热量是通过传导从火焰传导到食物上的。
Charge carriers play an important role electric conduction. A potential difference which is bridged by a conductor is also required to implement conduction. Metals are usually good electric conductors since they have delocalized electr*** that can flow and carry the current. Soluti*** such as acids have i*** which are free to employ as charged carriers. Therefore, acidic soluti*** act as electric conductors. Pure water does not conduct electricity, but fresh water can conduct electricity since fresh water contains a **all quantity of i***.
什么是归纳(induction)?
归纳法这一术语通常被称为定向。根据字典,定向是指自己或一个人的想法对周围环境或环境的调整或调整。显然,双方应该参与一个定向过程。同样,在一个诱导过程中,一个必须根据另一个来调整它的质量。
在物理学中,感应分为静电感应和电磁感应。静电感应是一个物体在外部电荷存在时产生的静电电荷的转化。考虑一个中性的金属球体。如果一根带电的棒靠近球体,中性原子就会电离并分裂成两部分。然后相似的电荷会互相排斥,形成如下的电荷几何结构。在这个过程中,杆和球体之间不需要接触。这种分裂纯粹是静电感应的结果。迈克尔·法拉第因为发现了电磁感应而获得了荣誉。电磁感应是由时变磁场引起的。通过改变导体周围的磁场,可以在导体上产生电动势。此过程不需要联系。电动势完全由电磁感应产生。
Electrostatic precipitators actively employ the concept of electrostatic induction to remove particles from industrial soot. The transformer is incorporated as a major component, from power stati*** to home appliances, It is used to increase the voltage as well as decrease the voltage. Power stati*** usually have step-up transformers to increase the voltage and feed to the tran**ission line, then there may be several points in the tran**ission line to step-down the voltage to a safe level to c***ume by home appliances. The most important thing about the transformer is that it has no direct coupling between the input (primary) and output (secondary), but transfers energy from primary to secondary. Relatively new application of electromagnetic induction is the induction cooker. It’s a soot-free, handy kitchen appliance.
传导(conduction)和归纳(induction)的区别
传导和感应的定义
传导:传导是热能通过相邻分子之间的碰撞传递的过程。
感应:感应是电能从一个物体转移到另一个物体而不接触物体的过程。
传导和感应特性
能量转移
传导:传导是利用物质传递能量的一种方式。
感应:感应不需要介质或接触来传递能量。
过程
传导:传导通路断开时,传导停止。
诱导:当双方无限期后退时,诱导停止。
渐变路径
传导:传导是一个端到端的过程。为了使传导发生,应产生电位差或温差。
诱导:诱导不需要梯度路径。
