网络扩展解释

热离子效应

热离子效应的中文拼音为"rè lí zǐ xiào yìng"。

热离子效应的英文解释是"Thermionic emission"，读作"θɜ:mɪˈɒnɪk ɪˈmɪʃən"。

热离子效应是指在热力学平衡下，高温下的固体中，部分电子获得了能够逃离材料表面束缚的能量而被弹出的现象。这些逃逸的电子称为热离子。

热离子效应在半导体器件中有着广泛的应用。例如，在热电子价位发射器件中，热离子效应被用于发射电子，从而产生电流。

英文用法

Thermionic emission is a phenomenon in which some electrons gain enough energy to escape binding at a material's surface in a thermodynamic equilibrium. These escaped electrons are known as thermions. It has wide applications in semiconductor devices. For example, in a thermionic valve device, thermionic emission is used to emit electrons, thus producing electric current.

英文例句

• The thermionic emission of electrons from metal surfaces is an important process in electron microscopy.
• Thermionic emission was used to produce electronic amplifiers before the development of transistors.
• Thermionic emission is a key process that must be understood in order to develop better semiconductor devices.

英文近义词

• Field emission (场发射): A similar effect caused by the application of a high electric field to a metal or semiconductor.

英文反义词

• Photoelectric emission (光电发射): An effect in which electrons are emitted from a material's surface as a result of incident light

英文单词常用度

根据Google Ngram Viewer的数据，"thermionic emission"这个词在英文书籍中的使用频率逐渐减少，但它在科技和工程领域仍然广泛使用。
