Definition of dipole in English:

dipole

noun ˈdʌɪpəʊlˈdaɪˌpoʊl

1Physics
A pair of equal and oppositely charged or magnetized poles separated by a distance.
〔物理〕偶极子
Example sentencesExamples
- Underwater mountains, which are usually volcanic, often have magnetic dipoles.
- Interaction between the in-plane components of the headgroup dipoles is attractive and decays as the inverse sixth power of distance.
- Dielectric constants of nonpolar solvents arise from induced dipoles.
- The succeeding positive slope arises due to the orientation of the headgroup dipoles.
- Dielectric constants of polar solvents are dominated by reorientation of their permanent dipoles.
1. 1.1Chemistry A molecule in which a concentration of positive electric charge is separated from a concentration of negative charge.
  〔化〕偶极
  Example sentencesExamples
  The longer the peptide, the less important is the effect of the helical dipole.
  The relative magnitudes of the molecular dipoles can be explained by the relative electronegativity differences of the atoms forming the bonds.
  If there is a separation of charge in an bond, it possesses a dipole.
  In this way, temporary dipoles are propagated through a liquid or solid.
  Van der Waals forces are the attractive forces of one transient dipole for another.
2An aerial consisting of a horizontal metal rod with a connecting wire at its centre.
偶极天线
Example sentencesExamples
- Marsis features three long antenna booms - a dipole and monopole - that broadcast very long wavelength radio waves toward the planet.
- These methods allow engineers to fabricate many different types of planar IR antennas, including dipoles, spirals, and patches.
- One of the simplest feeds for a microwave antenna is the dipole.
- The loss of the helical spring antenna is approximately 10 dB compared to a half-wave dipole.
- By this time, Dad and I had replaced the old dipole with a short Yagi array, horizontally polarized of course, and screwed to one of the crossbeams in the attic, so now we had three channels with excellent reception.

dipolar

adjective

Almost certainly it involves the strongly dipolar properties of the interfacial tryptophans that are present in both the [beta] 6.3 and [arrow up] [arrow down] [beta] 7.2 structures.
Example sentencesExamples
- The major difficulty with 19 F NMR in an anisotropic medium such as bicelles is the expected large residual dipolar coupling, which limits the length of the gradient encoding period.
- A small part of this spectral shift probably resulted from dipolar interaction with the AOT polar headgroup.
- This expression was summed over a Gaussian distribution of dipolar couplings corresponding to a distribution of isolated 13 C- 19 F spin pairs.
- The spatial proximities between labels are determined by heteronuclear dipolar couplings, which are measured by rotational-echo double resonance (Gullion and Schaefer, 1989 ab).
