ЧТО ОЗНАЧАЕТ СЛОВО EQUIPARTITION
Теорема об эквивалентности
В классической статистической механике теорема о равнораспространении является общей формулой, связывающей температуру системы со средними энергиями. Теорема равнораспределения также известна как закон равнораспределения, равнораспределение энергии или просто равнораспределение. Первоначальная идея равнораспределения заключалась в том, что в тепловом равновесии энергия распределяется поровну между всеми ее различными формами; например, средняя кинетическая энергия на степень свободы в поступательном движении молекулы должна быть равна величине ее вращательных движений. Теорема равнораспределения дает количественные прогнозы. Как и теорема вириала, она дает общую среднюю кинетическую и потенциальную энергии для системы при заданной температуре, из которой можно вычислить теплоемкость системы. Однако равнораспределение также дает средние значения отдельных компонентов энергии, такие как кинетическая энергия конкретной частицы или потенциальная энергия одной пружины.
Значение слова equipartition в словаре английский языка
Определение равнораспределения в словаре - это равное деление энергии системы в тепловом равновесии между различными степенями свободы. Этот принцип предполагался точным в классической физике, но квантовая теория показывает, что это справедливо только в некоторых частных случаях.
