英语词汇dipole的翻译、用法及例句-MX2U.com英汉词典

dipole

noun [ C ] uk/ˈdaɪ.pəʊl/ us/ˈdaɪ.poʊl/

(IN SCIENCE)

physics specialized偶极子

two poles that have opposite and equal electrical charge or magnetic force, with a space between them

Geomagnetic South Pole represents the axis of the Earth's magnetic dipole. 地磁南极代表地球磁偶极子的轴。

chemistry specialized偶极子

a molecule with an area of negative charge and an area of positive charge that are separated

Many molecules (such as those of water) are electric dipoles, meaning that they have a partial positive charge at one end and a partial negative charge at the other. 许多分子（例如水分子）都是电偶极子，也就是说分子的一端含部分正电荷，另一端含部分负电荷。

By Maxwell's time, it was clear that the electromagnetic field was the means by which electrical charges and magnetic dipoles act on each other at a distance.
If the dipolarity of the generator in the power system is lost, mechanical energy has to be fed into the shaft of the generators to restore the dipole.
The centre of positive charge does not coincide with the centre of negative charge; we say that the bond is polar or that it has a dipole.
The bent molecule H2O has a dipole, but the linear CO2 (O=C=O) does not.

(FOR RADIO)

(also dipole antenna)偶极子天线

a simple type of radio aerial (= a structure that receives or sends out radio signals) that is shaped like the letter T

With most FM radio stations today, a vertical dipole gives as much signal as a horizontal one. 对如今大多数的调频广播电台来说，垂直偶极子天线和水平偶极子天线发出的信号的强度是一样的。

The world's first radio astronomer, he presided over a field of dipoles (antennas) 3,500 feet in diameter while continuing his private research.
I use a 440mHz transmitter radio with a 6.5" horizontal dipole antenna.
