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
