Game physics engines scale back the simulation by avoiding such things as Brownian motion, which in turn minimizes the processing complexities of the simulation.

游戏物理引擎通过避免诸如布朗运动这样的东西来缩减仿真，进而最小化仿真的处理复杂性。

The idea is that share prices follow some gentle random walk away from an equilibrium, rather like motes of dust jiggling around in Brownian motion.

其想法在于，股票价格遵循偏离均衡的相当温和的随机漫步（random walk）原则，颇似布朗运动（Brownian motion）[5]中四处轻摆的花粉微粒[6]。

Brownian motion has been widely popular in many purely scientific fields, such as physics, economics, communications theory, biology, management science and mathematical statistics.

布朗运动及其本位主义已广泛地出现在许多纯科学领域中，如物理，经济，通信理论，生物，管理科学与数理统计等。

He says financial models built on Brownian motion have done a great deal of good.

Similarly, it appears that the limits to our threshold of hearing may actually be Brownian motion.

Brownian motion works best with truly random things, like little bits of pollen that bounce around with no rhyme or reason.
