ЧТО ОЗНАЧАЕТ СЛОВО DIFFUSION
диффузия
Диффузия - это чистое движение вещества из области высокой концентрации в область с низкой концентрацией. Это также называется движением вещества с градиентом концентрации. Градиент - это изменение значения величины с изменением другой переменной. Например, изменение концентрации на расстоянии называется градиентом концентрации, изменение давления на расстоянии называется градиентом давления, а изменение температуры на расстоянии называется градиентом температуры. Слово «диффузия» происходит от латинского слова «diffundere», что означает «распространяться». Отличительной особенностью диффузии является то, что она приводит к перемешиванию или массовому транспорту, не требуя массового движения. Таким образом, диффузию не следует путать с конвекцией или адвекцией, которые являются другими явлениями переноса, которые используют объемное движение для перемещения частиц из одного места в другое.
Значение слова diffusion в словаре английский языка
Первое определение диффузии в словаре - это действие или процесс распространения или распространения; дисперсия. Другим определением диффузии является многословие. Диффузия - также случайное тепловое движение атомов, молекул, кластеров атомов и т. Д. В газах, жидкостях и некоторых твердых телах.

The widespread diffusion of nuclear weapons would make many nations able, and in some cases also create the pressure, to aggravate an on-going crisis, or even touch off a war between two other powers for purposes of their own.
