Definition of Brownian motion in English:

Brownian motion

nounˌbraʊnɪən ˈməʊʃ(ə)nˌbraʊniən ˈmoʊʃən

mass nounPhysics

The erratic random movement of microscopic particles in a fluid, as a result of continuous bombardment from molecules of the surrounding medium.
〔物理〕布朗运动
Example sentencesExamples
- The voltage signal produced by the photodiode is calibrated in force units using the power spectrum of Brownian motion.
- The amplitude of the displacements of unattached beads diminishes with a constant slope of - 2, as expected for Brownian motion in a viscous medium (sugar water).
- Second, he explained the jittery dance of microscopic particles - Brownian motion - as the buffets of surrounding atoms.
- Filaments of the cytoskeleton are so thin they can be pushed around by the random movements, or so-called Brownian motion, of other, neighboring molecules.
- This does not occur in practice, since random forces such as Brownian motion perturb the cell's trajectory.

Origin

Late 19th century: named after Robert Brown (1773–1858), the Scottish botanist who first observed the motion.
