dielectric音标为:[ˌdaɪəˈlɪktɪk] ,翻译为“电介质”。速记技巧:直接提取词根“dielect”和后缀“ic”组合即可。
Dielectric这个词源自希腊语词根“di”(表示“两个”)和“leikros”(表示“界限”或“间隔”),因此它表示“隔膜”或“绝缘体”。
变化形式:
1. Dielectricity(电介质,绝缘体)
2. Dielectric constant(电介质常数)
相关单词:
1. Conductivity(导电性):这个词表示物体传导电流的能力,与绝缘体相对。
2. Insulator(绝缘体):与绝缘体相对应的词,表示不导电的物质。
3. Resistivity(电阻):表示物体对电流的阻碍程度,与导电性相关。
4. Electrical resistance(电阻器):用于控制电流的设备,与电阻相关联。
5. Electrostatics(静电学):研究带电物体之间相互作用和影响的一门学科,与绝缘体和电荷有关。
6. Dielectric breakdown(电介质击穿):指电介质在电场作用下发生物理变化的现象。
7. Dielectric layer(电介质层):指在某些材料中存在的绝缘层,用于隔离不同区域或防止电流泄漏。
8. Dielectric material(电介质材料):指具有绝缘特性的材料,广泛应用于电子和电气领域。
9. Dielectric function(电介质功能):指物质在电场作用下表现出的性质和行为,与绝缘体和导体的性质有关。
10. Dielectric effect(电介质效应):指某些物质在电场作用下产生的现象或变化,对电路和电子设备有重要影响。

英文小作文:
Dielectric Materials in Electronics
Dielectric materials are essential components in modern electronics, playing a vital role in the operation of capacitors, diodes, and other electronic devices. Dielectric materials allow electricity to flow through them, but only when a voltage is applied, which means they can store energy efficiently. The dielectric constant and dielectric loss of a material determine its performance in these devices. Understanding these properties is crucial for the development of advanced electronic systems.
