释义 | electron noun[ C ] uk /iˈlek.trɒn/ us /iˈlek.trɑːn/ an extremely small piece of matter with a negative electrical charge电子 Compare neutron proton Electricity - units A, a amp amperage coulomb erg kilowatt lumen megawatt microcoulomb milliampere muon ohm terawatt the Faraday constant volt voltage W, w watt wattage You can also find related words, phrases, and synonyms in the topics: Physics: atoms, molecules & sub-atomic particles An electric spark consists of a rush of electrons across the space between the two terminals. Cathode rays are electrons in rapid motion. The fixing of the wandering electron to a neutral atom creates a negative ion. The principal remedy is heat, because it engenders a higher rate of vibration of the electrons. We have seen that an electric current is really a flow of electrons. electron | American Dictionaryelectron noun[ C ] us/ɪˈlek·trɑn/ physics, chemistry the part of an atom with a negative electrical charge, which moves around the atom's nucleus (= central part) Examples of electronelectron It permits simulation of the coupled dynamics of valence electrons and ionic cores in a molecule or a material. The 13-cm radius outer wall is permitted to emit electrons where the plasma is in contact. Where the plasma is in contact with the outer wall, electron space-chargelimited emission is permitted. The mass of the plume slab is determined by the amount of material ejected from the target when thermalized by the electron beam. It is then essential that such plasmas can be accurately described in their fundamental parameters, namely electron density and temperature. The analysis we present is not restricted to electron-ion plasmas, the result is also valid for electron-positron plasmas. Charged particle acceleration by an intense wake-field excited in plasmas by either laser pulse or relativistic electron bunch. In this process, the energy absorbed by the electrons during the interaction with the laser pulse is converted into both radiation and ion kinetic energy. We observe that the value of the transverse emittance of the electron beam is a crucial parameter for the production of monochromatic radiation. These results are useful for description of electron-beam propagation in the solar corona, which is a source of sporadic radiation. The purpose of this paper is to study the original direction of the radiation excited by electron cyclotron maser instability or the beam-plasma instability. If the free electron remains free after the collision, we speak of a free-free collision. Evidence of enhanced effective hot electron temperatures in ultraintense laser-solid interactions due to reflexing. Suppression of the potential well prevents the free electrons from recombination and, thus, no high-energy photon can be emitted. These electrons may then be scattered into the chamber volume.
