A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
〔物理〕电场
Example sentencesExamples
Electricity flowing in a conductor (a wire) generates both a magnetic field and an electric field.
Switching off the electric field allows the ions to drop onto the silicon, where they bond to the surface in this pattern.
The electrons ejected in the direction of the electric field polarization of the laser light pulse are detected.
The laser's strong electric field forces a pair of electrons from a two-atom molecule, leaving two lone ions behind.
The ability of the sensor to completely transfer charge depends on the electric field strength between regions.
Electrically charged particles have electric fields around them as a result of their charge.
Since it is the electric field which causes the motion of charged particles, there can be no current inside the shell either.
These electrons accelerate in the electric field of the wake.
In a strong electric field, free electrons can be accelerated onto its inner surface.
Likewise, Faraday thought that electric fields somehow manipulated charged particles with ghostly hands.
The relationships between changing magnetic and electric fields are summarized in the well-known Maxwell's equations.
Ferroelectric materials can create an electric field the way iron magnets create a magnetic field.
This charge-shift couples with an electric field within a cell membrane, resulting in electrochromism.
The positively and negatively charged ions cause an electric field to form.
This lattice can trap the neutral atoms in potential wells because the electric fields of the lasers induce a dipole moment in the atom.
At the end of the trap, electric fields focus the ions into the heart of an electrostatic mirror.
Because the particles are electrically charged, electric fields can be used to accelerate them, just as the gravitational field accelerates a falling apple.
An electric field propagates and repels electrons on the opposite plate making it positively charged.
In this state, any tiny protrusions in the charge front focus the electric field around them.
X rays emerge when the electrons, accelerated by a strong electric field, slam into a tungsten target.
