Definition of quadrupole in English:

quadrupole

noun ˈkwɒdrʊpəʊlˈkwɑdrəˌpoʊl

Physics

1A distribution of electric charge or magnetization consisting of four equal monopoles, or two equal dipoles, arranged close together with alternating polarity and operating as a unit.
〔物理〕四极
as modifier the quadrupole moment
Example sentencesExamples
- The deuterium quadrupole echo spectra of the two samples are presented in Fig.7.
- Lowering the temperature appears to substantially shorten the quadrupole echo decay time of the prominent doublet component.
- Motions that change the quadrupole interaction while an echo is being formed contribute to echo decay.
- For this protein, representation of its electrostatic properties by a quadrupole moment seems more appropriate.
- The two populations differ in their averaged quadrupole splitting and in their 2 H chemical shift values.
- Such simulations can, however, display rapid small amplitude motions that modulate the quadrupole interaction about its average.
1. 1.1 A device using a quadrupole arrangement directed at one point to focus beams of subatomic particles.
  四极聚向设备
  Example sentencesExamples
  The plot in Fig.2 has a striking qualitative similarity to the observed NMR quadrupole splittings.
  In Q-Tof mass spectrometers ions are focused by a radio frequency lens before transmission to the quadrupole.
  We have used a microfabricated planar quadrupole as a test bed for evaluating DEP-based traps, using polystyrene beads as a model for cells.
