释义 | ion noun[ C ] physics, chemistry specializeduk /ˈaɪ.ɒn/ us /ˈaɪ.ɑːn/ an atom or small group of atoms that has an electrical charge because it has added or lost one or more electrons离子 See also Physics: atoms, molecules & sub-atomic particles acceptor alpha particle anti-radical antilepton antimatter antineutrino beta decay beta particle hadron Higgs boson interatomic interelectronic interionic monatomic multi-molecular multiparticle muon neutrino positron relative atomic mass Related wordionic -ion suffix uk / -ən/ us / -ən/(also-ation); (also-ition) added to verbs to form nouns showing action or condition: (加在动词后构成名词表示“行为,状态”) obsession着魔 restoration恢复 repetition重复 Linguistics: morphology & parts of words -athon affix affixation agglutinate agglutinative analytic contraction interfix ism libfix monomorphemic monosyllabic morpheme morphological suffix syllabify synthetic that'd that'll that's ion | American Dictionaryion noun[ C ] us/ˈɑɪˌɑn, -ən/ physics, chemistry an atom that has a positive or negative electrical charge as the result of adding or taking away an electron Examples of ionion The plume density is about 7.7 10 20 ions 0m 3. Entry and exit of ions into the simulation region can be represented as a first-order process. Here, cos represents the radial dispacement of the passing ion. The maximum position of the bremsstrahlung radiation cross-section gets closer to the target ion with increasing nonideal-plasma parameter. 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. Characteristics of ion emission from plasma produced by high-energy short-wavelength (438 nm) laser radiation. In order to define a radius for the ion one needs a constant value for the radius of the water. A force that exists only between charged molecules (ions) or surfaces. Current studies are being carried out to determine the pharmacology, ion dependence and molecular basis for larval tegumental serotonin transporters. One of the challenges facing simulation studies is to relate the molecular structures of channel components to the physiological properties of ion channels. Analytic model for studying heavy ion imploded cylindrical targets. It is thus mostly used for the simulation of lower-intensity ion-beam experiments. 12. Thus, there are more differences of principle rather than similarities in the processes of emission of ions and electrons from plasma. This result demonstrates that the ion energy increment due to the application of the magnetic field is not dependent on the ion charge state. Correlation's between fast ion collector signals and spectral line shapes of target ions has been established. These examples are from corpora and from sources on the web.
